Saturday, August 30, 2014 Wildfire Air Quality Summary for the Klamath Region

Air Quality Summary Report                                                             
Prepared by:  Andrea Nick (USDA-FS) and Willie Begay(USDA-FS)

Yesterday Winds pushed smoke to the northeast throughout the day causing high levels of smoke throughout the Scott and Shasta Valleys, with some impacts in Macdoel and beyond.  Communities located to the west of the fires such as those in the Trinity River drainage, and lower Klamath River drainage had limited smoke impacts. However, Seiad Valley and Happy Camp had an afternoon spike in smoke concentrations greater than the previous day.

Today Smoke will be pushed to the southeast and by mid-afternoon smoke impacts could reach Weaverville and Redding. Today’s conditions will be similar to yesterday.

Tomorrow A shift in wind direction is predicted.   A mostly northerly flow will push the smoke to the southward and westward.  This will cause the lower Klamath River drainage, Salmon River drainage to see an increase in smoke.  Scott Valley will retain smoke but the Shasta Valley should see improvements in air quality.

Air Quality Index
Potential Health Impacts
Actions to Reduce Smoke Exposure
Good
Air quality is satisfactory and poses little or no health risk
None
Moderate
Air quality is acceptable for most.  There may be moderate health concern for a very small number of individuals.
Sensitive individuals such as those with heart or lung disease, infants, children, pregnant women, or older adults should limit time spend outdoors and avoid strenuous outdoor activities.
Unhealthy for Sensitive Groups (USG)
Members of sensitive groups may experience health effects.  The general public is not likely to be affected.
Everyone should avoid prolonged exposure to smoke.  Sensitive individuals such as those with heart or lung disease, infants, children, pregnant women, or older adults should minimize exposure by staying inside where air is cleaner.  
Unhealthy
Everyone may begin to experience health effects.  These effects may be more serious for sensitive people.
Everyone should limit time spent outdoors and choose non-strenuous indoor activities.  Sensitive individuals such as those with heart or lung disease, infants, children, pregnant women, or older adults should stay indoors where air is clean.
Very Unhealthy
Triggers a health alert meaning everyone may experience more serious health effects
Everyone should limit time spent outdoors and preferably stay indoors where air is clean.   Staying indoors is especially important for sensitive individuals such as those with heart or lung disease, infants, children, pregnant women, or older adults.
Hazardous
Triggers health warnings of emergency conditions.  Everyone is very likely to be affected by serious health effects.
Everyone should avoid all outdoor activity.  Relief from smoke is best accomplished by leaving for cleaner air.  Alternately, remain indoors  where air is clean.

  1. I live in Tennant, CA. I have been living with wildfire smoke for a full month now (those damn west winds) and let me tell you when your town is smothered in wild fire smoke the air inside the house, as claimed by the air quality index, IS NOT CLEAN. Every breath I take in is smoke because the air outside is smoke. My chest feels like it is caving in and I spent the whole time inside my house. The air quality inside a structure is directly correlated to the air outside. It makes no sense that the air would be different inside the house unless one is using some kind of futuristic technology to transmute smoke into oxygenated, breathable air! It is ridiculous to state the air will be clean inside the home. In Tennant, we have been at the Hazardous level of smoke, believe me.
