Smoke from Northern Fires Impacting Del Norte, Humboldt, and Trinity
[Lightning] activity has started numerous fires throughout Oregon and Northern California. Two of these fires are producing smoke that could impacting our area. The Natchez fire started in Oregon and fire activity has moved into Northern California near the border. The Hendrix fire is near Ashland, Oregon is also active due to conditions and terrain.
The current weather forecast indicates that North East winds may cause the smoke from these fires to pool along the river drainages, impacting northern interior portions of Del Norte, Humboldt, and Trinity Counties. Air quality along the coast is expected to remain “Good” to “Moderate”. Interior areas can expect air quality conditions of “Moderate” to “Unhealthy for Sensitive Groups” with the potential for increased smoke along the river drainages.
Particulate Matter (PM2.5) monitors are presently in Crescent City, Weitchpec, Hoopa, Weaverville, and Eureka. Fire information can be found at http://inciweb.nwcg.gov/ or at www.calfire.ca.gov. Current weather information can be found at www.wrh.noaa.gov.
Health Information for Smoke Impacts
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.
If you can see, taste, or feel smoke, contact your local health department and/or primary healthcare provider. This is especially important if you have health concerns, are elderly, are pregnant, or have a child in your care.
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 “re-circulate” 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.
