Friday, August 22, 2014 - Air Quality Report - Klamath Fires

Air Quality Summary Report                                                                                        
Friday, August 22, 2014

Prepared by: Ryan Bauer, Kelly Palmer, and Ron Sherron        

Yesterday Northerly afternoon and evening winds combined with dry conditions lead to increased fire activity, particularly on the Frying Pan fire. Heavy smoke production only lightly affected Happy Camp until up-canyon winds pushed smoke into town after 9am. Scott Valley and Yreka were impacted in the evening as smoke that had been held aloft during the day settled into downwind valleys. Impacts were seen as far south as Redding by this morning.
Today Stronger northerly winds and low humidity will result in continued active burning and smoke production on the Frying Pan, Falkstein, Man, and Whites fires. The resulting smoke column may shelter and moderate other fires in the area. Early morning smoke impacts occurred in Scott Valley and Yreka as a result of overnight smoke settling.  Gusty northerly afternoon winds should disperse smoke impacting valleys and drainages. Winds begin to shift from northwesterly to northeasterly this evening, and may create areas of patchy smoke impacts to communities in the Klamath and Trinity River drainages possibly reaching coastal communities by early morning. 
Tomorrow   Clear skies, continued warming and drying through the weekend may lead to continued active fire behavior.  Light winds will allow diurnal patterns to dominate and smoke impacts may become increased in valley locations.  Models suggest that as high pressure develops over the area the potential for valley pooling of smoke and stronger inversions will increase during early morning hours.

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
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. Thanks a bunch for these reports! The air quality ratings and predictions are most helpful in dealing with this situation. (I am an elderly person with a heart condition living in Sawyers Bar and smoke is my major concern with these fires.) Foster Boone
