08/08/14 Idaho DEQ Smoke Forecast

Updated 1000 MDT Friday, August 8, 2014

Valid through Noon MDT Monday, August 11, 2014

Smoke Outlook

Most of Idaho has maintained Good levels of air quality except for north Idaho, which is currently experiencing Moderate conditions this morning due to the fires burning in Washington, Oregon, California, and the Clearwater Basin.  Even with periods of Moderate, the 24hr AQI was in the Good category except for parts of the Idaho Panhandle and Clearwater Basin.

A cut-off low will settle over California, steering warm southerly winds into Idaho this weekend.  A Rex block is forecast to develop over the Pacific Northwest by Sunday which will further increase temperatures.  These conditions will favor extreme fire behavior and therefore, produce more smoke on Sunday and Monday.  Today, there is a threat of thunderstorms across the Clearwater and Southeast and Eastern Highlands.  Any storms that do develop will be weak as the locations of favorable shear and moisture are not together.

Smoke impacts today will be similar to yesterday and confined mostly to light smoke across the northern part of state, north of the Salmon River.  Primary sources will continue to be fires burning in California, Oregon, and Washington.  Fires across the Clearwater will continue to create locally smoky and hazy conditions.  Light smoke and haze should be expected through the weekend with a chance for increasing smoke Sunday into Monday.

Smoke forecasts are dependent on predicted fire growth and weather.  If conditions change unexpectedly, impacts could occur.  When visibility starts to go below 5 miles, sensitive groups should minimize outdoor activities.  Everyone else should minimize prolonged or physical activity outdoors.  Refer to the Smoke and Health Tab on the Idaho Smoke Information Blog for additional health information. 

Your eyes are your best tools to determine if it’s safe to be outside.  Even if you smell smoke, the air quality may still be good.
