Air Quality Management District warns of possible wildfire smoke impacts through Sunday
Air Pollution Control Officer Doug Gearhart said the smoke and haze visible around Lake County has so far remained outside of the populated areas of the Lake County air basin.
However, winds are expected to start shifting which could result in smoke from the Walbridge fire in Sonoma County, the LNU Lightning Complex in Lake, Napa, Yolo and Solano counties, and the August Complex in the Mendocino National Forest settling into the Lake County air basin.
All areas of Lake County may experience periods of “moderate” to “unhealthy” conditions primarily starting Saturday, depending on the wind, Gearhart said.
Gearhart said regional wind patterns are forecast to start moderate changes beginning overnight into Saturday. This forecast is based on the latest weather, monitoring, fire activity information and will be updated as necessary.
The district is actively monitoring the smoke impacts throughout the county. Go to www.lcaqmd.net and follow the link to “Current Air Quality Index at: purpleair.com” for current particulate levels around the county.
Current particulate levels in Lake County are in the range from “good” to “moderate.” Should particulate levels reach “unhealthy” levels, everyone needs to take steps to protect themselves from exposure, said Gearhart.
Concentrations of smoke may vary depending upon location, weather, and distance from the fire. Smoke from wildfires and structure fires contain harmful chemicals that can affect your health. Smoke can cause eye and throat irritation, coughing, and difficulty breathing.
People who are at greatest risk of experiencing symptoms due to smoke include: those with respiratory disease (such as asthma), those with heart disease, young children, and older adults.
These sensitive populations should stay indoors and avoid prolonged activity. All others should limit prolonged or heavy activity and time spent outdoors. Even healthy adults can be affected by smoke. Seek medical help if you have symptoms that worsen or become severe.
Follow these general precautions to protect your health during a smoke event:
• Minimize or stop outdoor activities, especially exercise.
• Stay indoors with windows and doors closed as much as possible.
• Do not run fans that bring smoky outdoor air inside – examples include swamp coolers, whole-house fans, and fresh air ventilation systems.
• Run your air-conditioner only if it does not bring smoke in from the outdoors. Change the standard air conditioner filter to a medium or high-efficiency filter. If available, use the “recirculate” or “recycle” setting on the unit.
• Do not smoke, fry food, or do other things that will create indoor air pollution.
If you have lung disease (including asthma) or heart disease, closely monitor your health and contact your doctor if you have symptoms that worsen.
Consider leaving the area until smoke conditions improve if you have repeated coughing, shortness of breath, difficulty breathing, wheezing, chest tightness or pain, palpitations, nausea, unusual fatigue, lightheadedness.
“While we know that this is an added burden for everyone who has been dealing with the risks from COVID for all of these months, we definitely encourage folks to pay attention to the air quality and to take steps to protect themselves and their families,” said Lake County Public Health Officer Dr. Gary Pace.
Updated guidance from the CDC is available on reducing wildfire smoke exposure given COVID-19 considerations.
