Presently, the skies are blue and winds are expected to keep the remaining major Yolla Bolly and Lime Complex wildfires genrated smoke out of Lake County through Tuesday.

Residual smoke can be expected to remain throughout all areas of Northern California, including Lake County until the numerous lightning caused wildfires are out. All fires are presently dispersing smoke to a higher height and diluting more during transport, partially mitigating any transport of smoke from distant fires.

Lake County's Air Quality expected to be Moderate to Unhealthy for Sensitive Group through the Weekend

Air Quality in Lake County has Degraded from Smoke Intrusions
(Joint Public Information Release of the Health Department and AQMD)

RELEASE UPDATE of July 25th, 2008 @ 16:30

Smoke from Northern California wildfires continues to impact Lake County. Using the Federal Air Quality Index (AQI) for particulate matter, Lake County’s air quality is expected to be in the moderate range for a 24 hour average. Although the 24 hour average may be moderate trending to unhealthy for sensitive groups, mid-day to early evening conditions have been in the unhealthy for sensitive groups to unhealthy range. Conditions are expected to improve slightly for Saturday into Sunday with West to Northwest winds developing. North to Northwest winds will bring smoke back into the basin and could cause unhealthy conditions to develop.

Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous in young children, the elderly, individuals with heart conditions or chronic lung disease such as asthma, bronchitis and other respiratory conditions.

Lake County Public Health Officer Dr. Karen Tait advises area residents to be
cautious. “Variable weather conditions and ongoing fire activity may result in localized areas of reduced air quality, which could pose health risks to people with underlying health conditions. Since we can’t always predict when and where ‘pockets’ of poorer air quality may occur, it is prudent to be careful until conditions stabilize.”

Individuals with asthma, bronchitis, emphysema and other lung or heart diseases should carefully adhere to their medical treatment plans and maintain at least a five-day supply of supply of prescribed medications. They should limit outdoor activity and unnecessary physical exertion. Drinking plenty of water to avoid drying of the airways is generally recommended, unless restricted for medical reasons.

Dust masks are not protective against the most harmful pollutants caused by wildfire smoke that drifts to nearby areas. They are useful in filtering out the larger particles and ash that are encountered in burn areas and should be considered when recovering property or cleaning areas that have burned. Air purifying respirators, such as N-95 filtering face pieces, may be effective in reducing harmful particulate matter, but also increase the work of breathing, can lead to physiologic stress, and are not recommended for the general public in Lake County. Their use should be limited to individual circumstances requiring additional protection in personnel trained and familiar with the proper fitting and use of these devices.

Mechanical air filtering units with HEPA filters, can be useful. It is important that the size and the air flow of the unit be matched to the indoor space it is intended to treat. There are a variety of other devices marketed to purify air that should be avoided, as they might be ineffective under wildfire circumstances and some can actually worsen the air quality by producing ozone.

The Yolla Bolly complex, Lime complex and numerous other wildfires continue to burn in Northern California resulting in smoke, haze and degraded air quality, though progress has been made on these federal land wildfires. The Soda complex wildfire is 95% contained as of July 24th and currently is a minor impact for the county. West to Northeast winds have transported smoke to the Lake County Air Basin with conditions expected to remain unchanged through the weekend. Unhealthy air quality conditions may develop and persist should winds shift to a more northerly flow. Residual smoke can be expected to remain throughout all areas of Northern California, including Lake County, until the wildfires are completely contained.

Lake County’s air has improved this week. Though our normal blue skies are sometimes missing, no exceed of a health-based State or Federal Air Quality Standard has occurred this week and no exceed is expected through July 22nd. Lake County experienced increased smoke impacts on Saturday, but only reaching 59% of the Air Quality Standard. Today so far has been good and is expected to continue through the day. Using the Federal Air Quality Index (AQI) for particulate matter, Lake County’s air quality is expected to be in the good to moderate range. The AQI for particulate is expected to remain well below 101 where an unhealthy alert is given.

The Mendocino Lighting Complex fire was fully contained Thursday evening but numerous wildfires continue to burn in Northern California resulting in some smoke, haze and degraded air quality, though substantial progress has been made on these wildfires. West to Northeast winds could transport some smoke to the Lake County Air Basin but conditions are expected to improve from moderate on Saturday to good by Sunday. Continued West to Southwest winds have kept smoke to the North of Lake County, but wind directions do shift resulting in the return of some smoke. Some confined valleys in the Northern part of the county may continue to experience periods of localized moderate impacts as smoke settles into those locations, but most of Lake County should return to the good range as more westerly winds develop. Residual smoke can be expected to remain throughout all areas of Northern California, including Lake County, until the wildfires are completely contained.

Lake County’s Air Quality expected to remain in the Good to Moderate Range Through Friday July 18th - RELEASE UPDATE: July 17, 2008

Contact:  Douglas Gearhart, Deputy APCO or Warren Massie, AQT 263-7000

Lake County’s air has improved this week. Though our normal blue skies are sometimes missing, no exceed of a health-based State or Federal Air Quality Standard has occurred this week and no exceed is expected on July 18th. Using the Federal Air Quality Index (AQI) for particulate matter, Lake County’s air quality is expected to be in the good to moderate range. The AQI for particulate is expected to remain well below 101 where an unhealthy alert is given.

Numerous wild fires continue to burn in Northern California resulting in some smoke, haze and degraded air quality, though substantial progress has been made on these wildfires. West to Northeast winds could transport some smoke to the Lake County Air Basin but any impact is expected to be minor. Continued West to Southwest winds have kept smoke to the North of Lake County , but wind direction could shift resulting in the return of some smoke. Residual smoke can be expected to remain, though at a reduced level, throughout all areas of Northern California, including Lake County until the wildfires are out.

UNHEALTHY FOR SENSITIVE GROUPS ALERT Continues for Friday July 11, 2008

Air Quality in Lake County has Degraded from Smoke Intrusions - Caution is Urged
(Joint Public Information Release of the Health Department and AQMD)

RELEASE UPDATE of July 9th Release: July 10, 2008 @ 16:00

CONTACTS:

Dr. KarenTait, Health Officer @ 263-1090   Bob Reynolds or Doug Gearhart @ 263-7000
Lake County Health Department                   Lake County Air Quality Management District

Wildfires continue to burn in Northern California and result in smoke, haze and degraded air quality. Because of the weather patterns and control of many of the fires most of Lake County has experienced improved air quality in the past week. July 10th is estimated to exceed the Federal and State health based particulate standard for ultrafine particulate by 175%,  The standards are designed to protect sensitive groups of the population.  The prediction for tomorrow is for some improvement, but for a continued "UNHEALTHY FOR SENSITIVE INDIVIDUALS ALERT " in Lake County, given the present degraded air quality and expected meterology.

Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous for sensitive individual including young children, the elderly, individuals with heart conditions or chronic lung disease such as asthma, bronchitis and other respiratory conditions.  The heat can make the stress worse, especially during physical activities.

Even though local hospitals report no unusual increases in illness likely to be related to poor air quality, Lake County health officials recommend taking simple precautions in order to stay healthy. Lake County Public Health Officer Dr. Karen Tait advises residents near the fires be prepared. Individuals with asthma, bronchitis, emphysema and other lung or heart diseases should make sure that they have at least a five-day supply of any prescribed medications. Individuals with asthma should carefully follow their asthma management plans. Anyone, regardless of known health conditions, should seek medical attention if they experience unusual symptoms of chest pain, chest tightness, or shortness of breath. Sensitive individuals should be prepared to stay indoors, avoid vigorous physical activity and use the "recirculation" function on the air conditioner if available. Strong consideration should be given to moving planned outdoor events to an indoor location or rescheduling them, especially if they involve sports or similar activities. Lake County Public Health Officer, Dr. Karen Tait, notes that many of the same people who have been advised to take precautions related to recent reductions in air quality from wildfire activity are also susceptible to heat-related illness and should take special care. It is important to stay hydrated, drink adequate water to ensure you do.

Dust masks are not protective against the most harmful pollutants caused by wildfire smoke that drifts to nearby areas. They are useful in filtering out the ash and larger particles that are encountered in burn areas and should be considered when recovering property or cleaning areas that have burned. Air purifying respirators, such as N-95 filtering face pieces, may be effective in reducing harmful particulate matter, but also increase the work of breathing, can lead to physiologic stress, and are not recommended as a general protective measure. Their use should be limited to individual circumstances requiring addition protection (http://bepreparedcalifornia.ca gov/EPO/BeInformed /NaturalDisasters/Wildfires/CleanupFireAsh.htm), preferably in personnel trained and familiar with the proper fitting and use of these devices.

The UNHEALTHY FOR SENSITIVE INDIVIDUALS DAY results from smoke transported by winds. Presently the Mendocino Complex is the primary source of smoke but other fires including the Butte Complex have a potential to also cause significant degradation. The Soda Complex in the MNF continues to burn and is contributing smoke with northerly winds.  Good progress has been made in containing this complex of fires. Northerly winds will bring smoke into the Clear Lake basin from this and several other larger fires burning north of Lake County.

Residual haze and particulate from the many ongoing wildfires can be expected to continue throughout areas of Northern California, including Lake County until the numerous fires are out.

Wildfires continue to burn in Northern California and result in smoke, haze and degraded air quality. Because of the weather patterns and control of many of the fires most of Lake County has experienced improved air quality in the past week. July 9 is estimated to be near the allowed  Federal health based particulate standard for ultrafine particulate, designed to protect sensitive groups of the population.  The prediction for tomorrow given EXPECTED wind conditions and levels of particulate and ozone presently in the air is for conditions to continue and recommendation for an "UNHEALTHY FOR SENSITIVE INDIVIDUALS ALERT " in Lake County.

Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous for sensitive individual including young children, the elderly, individuals with heart conditions or chronic lung disease such as asthma, bronchitis and other respiratory conditions.  The heat can make the stress worse, especially during physical activities.

The UNHELATHY FOR SENSITIVE INDIVIDUALS DAY results from smoke transported by winds. Presently the Butte Complex is the primary source, but with changing wind directions, the Mendocino Complex will be the primary source of smoke. Currently the smoke is being transported to sea within a circulation cell, and may return back over Northern California in a wide band of smoke filled air which if combined with new smoke as it passes over ongoing fires could cause significant deterioration of our air quality. The smoke and sunlight cause chemical reactions in the air that further reduces visibility by forming secondary particles in addition to those already in the smoke. These particles draw the moisture out of the air, growing in number and size, making the haze even worse. 

The third wildfire complex of concern is the Soda Complex burning in the MNF.  Good progress has been made in containing this complex of fires. Northerly winds, which are predicted, will bring smoke into the Clear Lake basin from this and several other larger fires burning north of Lake County. Several wildfires exist to east of Lake County in the Sierra foothills and presently are contributing to degraded air quality in Lake County.

Residual haze and particulate from the many ongoing wildfires can be expected to continue throughout areas of Northern California, including Lake County until the numerous fires are out.

UNHEALTHY FOR SENSITIVE INDIVIDUALS ALERT on Wednesday July 9, 2008

Air Quality in Lake County has Degraded from Smoke Intrusions


Caution is Urged ON Wednesday July 9, 2008

Lake County Health Department                   Lake County Air Quality Management District


Numerous, wildfires continue to burn in Northern California and result in smoke, haze and degraded air quality. Because of the weather patterns and control of the Wild and Walker fires most of Lake County has experienced improved air quality. While values have ranged between 32% to 71% of allowed State and Federal health based particulate standards for small respirable particulate and the ultrafine, inhalable, particulate, designed to protect sensitive groups of the population.  The prediction for tomorrow given EXPECTED wind conditions and levels of particulate and ozone presently in the air, is that tomorrow will be an “UNHEALTHY FOR SENSITIVE INDIVIDUALS ALERT ” in Lake County.

 

Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous for sensitive individual including young children, the elderly, individuals with heart conditions or chronic lung disease such as asthma, bronchitis and other respiratory conditions.  The heat can make the stress worse, especially if exercising hard.

 

Even though local hospitals report no unusual increases in illness likely to be related to poor air quality, Lake County health officials recommend taking simple precautions in order to stay healthy. Lake County Public Health Officer Dr. Karen Tait advises residents near the fires be prepared. Individuals with asthma, bronchitis, emphysema and other lung or heart diseases should make sure that they have at least a five-day supply of any prescribed medications. Individuals with asthma shouldcarefully follow their asthma management plans. Anyone, regardless of known health conditions, should seek medical attention if they experience unusual symptoms of chest pain, chest tightness, or shortness of breath. Sensitive individuals should be prepared to stay indoors, avoid vigorous physical activity and check for a "recirculation" function on the air conditioner.  If smoke is present, it will be easier to breathe indoors if air is recirculating instead of drawing smokey air from outdoors. Strong consideration should be given to moving planned outdoor events to an indoor location or rescheduling them, especially if they involve sports or similar activities. Lake County Public Health Officer, Dr. Karen Tait, notes that many of the same people who have been advised to take precautions related to recent reductions in air quality from wildfire activity are also susceptible to heat-related illness and take special care. Be sure to stay hydrated.

 

Dust masks are not protective against the most harmful pollutants caused by wildfire smoke that drifts to nearby areas. They are useful in filtering out the ash and larger particles that are encountered in burn areas and should be considered when recovering property or cleaning areas that have burned.

The UNHELATHY FOR SENSITIVE INDIVIDUALS DAY results from smoke transported by winds. Presently the Mendocino Lightning Complex and the Butte Complex are the primary source. At DIFFERENT times smoke can be transported to sea within a circulation cell, and then return back over Northern California in a wide band of smoke filled air and combine with new smoke as it passes over ongoing fires. The smoke and sunlight cause chemical reactions in the air that further reduces visibility by forming secondary particles in addition to those already in the smoke. These particles draw the moisture out of the air, growing in number and size, making the haze even worse. 

 

The other wildfires of primary concern are the Soda Complex burning in the MNF, and good progress has been made in containing this complex of fires. Northerly winds, should they occur, will bring smoke into the Clear Lake basin from this and several other larger fires burning north of Lake County. Several wildfires exist to east of Lake County in the Sierra foothills and presently are contributing to degraded air quality in Lake County.

 

Residual haze and particulate from the many ongoing wildfires can be expected to continue throughout areas of Northern California, including Lake County until the numerous fires are out.

Lake County’s Air Quality Continues in the Good to Moderate Range Despite Smoke From Fires
RELEASE UPDATE: July7, 2008 @ 16:15

Contact:  Robert Reynolds, APCO & Douglas Gearhart, Deputy APCO263-7000

Lake County’s air has greatly improved from the initial heavy smoke of the numerous wildfires continuing through today. Though our normal blue skies are often missing, no exceed of a health based State or Federal Air Quality Standard has occurred for over a week. Levels have only reached 71% of any air standard limit, to include the PM 2.5 standard at the highest, since June 29th.

Using the Federal Air Quality Index (AQI) for particulate matter, Lake County’s air quality is classified as good to moderate, though many would not agree the air is good. The highest AQI for particulate was 70, which is considered moderate and is below the health warning for sensitive individuals, which start at a score of 101.

The numerous, lightning-strike caused fires continue to burn in Northern California and results in smoke, haze and degraded air quality, though substantial progress being made by the fire agencies is also lowering smoke levels for more distant locations. In areas of Northern California, adjacent to wildfires, Unhealthy and Very Unhealthy warnings are continuing.

The prevailing West to Northwest winds have not pushed as much smoke into Lake County in recent days as would be expected, and continues to be a concern. The Mendocino Lightning Complex, Mendocino National Forest wildfires, as well as numerous other fires continue to burn, and though progress has been made these wildfires will transport smoke to the Lake County Air Basin with West to Northeast winds.

Residual smoke remains present at a reduced level from the many fires and is likely to continue throughout all areas of Northern California, including Lake County until the wildfires are out.

Lake County’s air has greatly improved from the heavy smoke of last week starting with a weather change on Saturday afternoon continuing through today. Though our normal blue skies are often missing, no exceed of a health based State or Federal Air Quality Standard has occurred this week. Levels have only reached 70% of any air standard limit, to include the PM 2.5 standard at the highest.

The highest AQI for particulate was 70, which is considered moderate and is below the health warning for sensitive individuals, which start at a score of 101.

The numerous, lightning-strike caused fires continue to burn in Northern California and results in smoke, haze and degraded air quality, though substantial progress is being made by the fire agencies. In areas of Northern California, adjacent to wildfires, Unhealthy and Very Unhealthy warnings are continuing. Some areas have even issued Hazardous Advisories, the highest advisory level.

The Southwest winds instead of the prevailing West to Northwest winds are credited with the continued improved air quality conditions in Lake County. They are expected through July 4th. The Mendocino Lightning Complex, Mendocino National Forest wildfires, as well as numerous other fires continue to burn, and though progress has been made these wildfires will transport smoke to the Lake County Air Basin with West to Northeast winds.

Residual smoke remains present at a reduced level from the many fires and is likely to continue throughout areas of Northern California, including Lake County until the wildfires are out.

Reduced Smoke Results in Good Air Quality in Lake County
Caution is Still Urged
(Joint Public Information Release of the Health Department and AQMD)

RELEASE DATE: July1, 2008 @ 16:00

Dr. KarenTait, Health Officer @ 263-1090   Bob Reynolds or Doug Gearhart @ 263-7000
Lake County Health Department                   Lake County Air Quality Management District

Numerous, lightning-strike caused fires continue to burn in Northern California and result in smoke, haze and degraded air quality. Because of the weather patterns and control of the Wild and Walker fires most of Lake County has experienced improved
healthful air beginning Saturday afternoon. Many areas of Northern California remain
under health warnings for air quality. Values have ranged between 32% to 71% of of allowed State and Federal health based particulate standards, designed to protect sensitive groups of the population, for small respirable particulate and the ultrafine, inhalable, particulate. In recent days the ozone levels have remained below 86% of the State Standard and less than 65% of the Federal Standard. Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous in young children, the elderly, individuals with heart conditions or chroniclung disease such as asthma, bronchitis and other respiratory conditions.


In spite of improvements in local air quality over the past few days, Lake County Public Health Officer Dr. Karen Tait advises area residents to be cautious in resuming normal activities. “Variable weather conditions and ongoing fire activity may result in localized areas of reduced air quality, which could still pose health risks to people with underlying health conditions. Since we can’t always predict when and where ‘pockets’ of poorer air quality may occur, it is prudent to be careful until conditions stabilize.” Individuals with asthma, bronchitis, emphysema and other lung or heart diseases should carefully adhere to their medical treatment plans and maintain at least a five-day supply of prescribed medications. They should limit outdoor activity and unnecessary physical exertion. Air conditioning that recirculates indoor air should be used, when available. Drinking plenty of water to avoid drying of the airways is recommended, unless restricted for medical reasons.

Dust masks are not protective against the most harmful pollutants caused by wildfire smoke that drifts to nearby areas. They are useful in filtering out the ash and larger particles that are encountered in burn areas and should be considered when recovering property or cleaning areas that have burned. Air purifying respirators, such as N-95 filtering face pieces, may be effective in reducing harmful particulate matter, but also increase the work of breathing, can lead to physiologic stress, and are not recommended as a general protective measure. Their use should be limited to individual circumstances requiring addition protection (http://bepreparedcalifornia.ca gov/EPO/BeInformed /NaturalDisasters/Wildfires/CleanupFireAsh.htm), preferably in personnel trained and familiar with the proper fitting and use of these devices.

The improved air quality is a direct result of the progress in controlling the wildfires and the sustained Southerly transport winds. Presently the Mendocino Lightning Complex, is the primary air quality concern for Lake County as winds may shift back to the prevailing west to northwest. The complex is located Northwest of Ukiah, consists of 123 fires with 43 active fires and 37,700 acres burned, it is still only 38% contained. Smoke can be trapped in the cooler marine air layer and transported inland with poor dispersion, causing elevated smoke impacts. At times smoke can be transported to sea within a circulation cell, and then return back over Northern California in a wide band of smoke filled air. The smoke and sunlight cause chemical reactions in the air that further reduces visibility by forming secondary particles in addition to those already in the smoke. These particles draw the moisture out of the air, growing in number and size,making the haze even worse.

The other wildfires of primary concern is the Soda Complex burning in the MNF, and good progress has been made in containing this complex of fires. Northerly winds, should they occur, will bring smoke into the Clear Lake basin from this and several other larger fires burning north of Lake County. Several wildfires exist to east of Lake County in the Sierra foothills and may cause degraded air quality in Lake County.

Residual haze and particulate from the many ongoing wildfires can be expected tocontinue throughout areas of Northern California,   including Lake County until thenumerous fires are out.

Lake County’s Air Quality Back in Attainment with all State and Federal Air Quality Standards.

Lake County’s air quality continues to improve from the heavy wildfire smoke of last week. The Southwest winds instead of the prevailing West to Northwest are credited with the present improved air quality conditions. Air pollution levels have dropped below all health based air quality standards since Sunday, although residual smoke remains in some areas. South to Southwest winds are expected to continue through tomorrow. Numerous, lightning-strike caused fires continue to burn in northern California and result in smoke, haze and degraded air quality in other areas of northern California. Many of the wildfires have grown to thousands of acres and smaller fires remain numerous. The Walker fire in eastern Lake County is reported 100% contained, which is great news for Lake County. The Soda Complex Fire burning in northern Lake County within the Menodcino National Forest has grown to 4,150 acres and is near 60% contained.The Mendocino Lightning Complex, Northwest of Ukiah, remains the most likely to impact Lake County’s air, especially if prevailing transport winds return. The over 123 fires have grown to 37,200 acres burned, with 54 active fires which are now 38% contained. These fires have been the primary source of smoke entering the Lake County air basin during last week. The Mendocino National Forest fires could transport smoke back to the Clear Lake basin with a north wind.

Residual haze and particulate from these many fires can be expected to continue throughout areas of Northern California, including Lake County until the numerous wildfires are out.

Lake County gets a Reprieve from Heavy Smoke of Numerous Wildfires
(Public Information Release of the AQMD)

RELEASE DATE:June 29, 2008 12:33:44 PM PDT

Contact: Doug Gearhart or Cheri Kendrick @ 263-7000; Lake County Air Quality Management District

Lake County got a reprieve from the heavy smoke of the last week starting with a weather change on Saturday afternoon continuing into Sunday afternoon. No health based exceeds occurred, though residual smoke remains, and by Sunday midday even the visibility was nearing the State standard. Numerous, lightning-strike caused fires continue to burn in northern California and result in smoke, haze and degraded air quality. In other areas of northern California, adjacent fires have caused unhealthy and very unhealthy warnings. In Butte County hazardous warnings have been issued as standards have been exceeded by a factor of over 800%. Many of the wildfires have grown to thousands of acres and smaller fires remain numerous. The Walker fire in eastern Lake County is reported 100% contained at 14,500 acres, which is great news for Lake County. The Mendocino Lightning Complex, Northwest of Ukiah, remains the most likely to impact Lake County’s air, especially if prevailing transport winds return. The over 100 fires have grown to 35,700 acres burned, with 60 active fires which are only 5% contained. These fires have been the primary source of smoke entering Lake County basin during last week. The Southwest winds instead of the prevailing West to Northwest are credited with the present improved air quality conditions. In the Mendocino Forest two large lightning caused complexes continue to burn and will transport smoke to the Clear Lake basin with a north wind.

Residual haze and particulate from these many fires can be expected to continue throughout areas of Northern California, including Lake County until the numerous wildfires are out.

 

Smoke From Numerous Wildfires Continue to Cause Air Quality Standard Exceeds in Lake County
(Joint Public Information Release of the Health Department and AQMD)

RELEASE DATE:June 27, 2008


CONTACTS:

Dr. KarenTait, Health Officer @ 263-1090   Bob Reynolds or Doug Gearhart @ 263-7000
Lake County Health Department                   Lake County Air Quality Management District

Numerous, lightning-strike caused fires continue to burn in northern California and result in smoke, haze and degraded air quality that continue to exceed State and Federal health standards for particulate throughout northern California, including Lake County on Thursday and Friday. Many of the wildfires have grown to thousands of acres and smaller fires are numerous. The Walker fire in eastern Lake County has grown to 14,500 acres and is 70% contained. The Mendocino Lightning Complex, Northwest of Ukiah, consists of 121 fires with 72 active fires and 27,000 acres burned, it is still only 5% contained, and it has been the primary source of smoke entering Lake County the last two days. Saturday may result in a weather break that will improve air quality, at least temporarily, as air from the Southwest instead of the prevailing West to Northwest are predicted.


Air Monitoring data continues to show violations of health based standards to include the small respirable particulate State Ambient Air Quality Standard and the Federal ultrafine, inhalable, particulate air standard which was exceeded by up to 277%. The levels would be characterized as moderate to unhealthy air quality. The ozone levels have approached but not exceeded the state Standard and remain less than 75% of the Federal Standard.


Smokey conditions can cause irritation of the eyes, nose and air passages, which can be hazardous in young children, the elderly, individuals with heart conditions or chronic lung disease such as asthma, bronchitis and other respiratory conditions.
Even though local hospitals report no unusual increases in illness likely to be related to poor air quality, Lake County health officials recommend taking simple precautions in order to stay healthy. Because of the uncertainty of fire conditions, Lake County Public Health Officer Dr. Karen Tait advises residents near the fires to be prepared. Individuals with asthma, bronchitis, emphysema and other lung or heart diseases should make sure that they have at least a five-day supply of any prescribed medications. Individuals with asthma should
carefully follow their asthma management plans. Anyone, regardless of known health conditions, should seek medical attention if they experience unusual symptoms of chest pain, chest tightness, or shortness of breath. Residents who live near the affected areas should be prepared to stay indoors, avoid vigorous physical activity and check for a "recirculation" function on the air conditioner.
If smoke is present, it will be easier to breathe indoors if air is recirculating instead of drawing smokey air from outdoors. Strong consideration should be given to moving planned outdoor events to an indoor location or rescheduling them, especially if they
involve sports or similar activities.


The continued poor air quality is a direct result of these dispersed, numerous wildfires within the California Coastal Mountains. Smoke is trapped in the cooler marine air layer and transported inland, causing the smoke impacts. At times smoke can be transported to sea within a circulation cell, and then return back over northern California in a wide band of smoke filled air. The smoke and sunlight cause chemical reactions in the air that further reduces visibility by forming secondary particles in addition to those
already in the smoke. These particles draw the moisture out of the air, growing in number and size, making the haze even worse.

Residual haze and particulate from these fires can be expected to continue throughout
areas of Northern California, including Lake County until the numerous fires are out.


Lake County Citizens and Visitors are asked to refrain from personal fireworks use!

(Joint Public Information Release: Lake County Fire Chiefs Association and Air Quality Management District)

RELEASE DATE:June 25, 2008

The Lake County Fire Chiefs Association and Lake County Air Quality Management District is pleading with the public to refrain from use of personal fireworks this year in order to lower the fire hazard for us all. Enjoy the larger fireworks shows that are conducted in a fire safe manner, over the lake and far from personal exposure to individuals. Firework sales and use are legal only within the City of Lakeport, sales or USE IS ILLEGAL IN ALL OTHER AREAS OF LAKE COUNTY AND THE CITY OF CLEARLAKE. The resource demand of fire agencies is depleted, any additional wildfires, even if they are small, will overburden fire fighters and further degrade our air quality. Thank you for your support and cooperation.
