Air quality update on Tuesday 19 August 2014

Air quality remains Good in much of the state, with moderate air in parts of the Columbia basin. Wildfires are smoldering but few are producing large plumes. Last week’s unusually large dumping of rain was a game changer.

West- northwest winds will kick up as a dry cold front passes through eastern Washington today before turning southwest and subsiding somewhat by Wednesday evening. Though this can literally fan the flames, temperatures are not expected to rise too high and aid fire growth all that much. Smoke impacts from fires outside Washington is likely to be low. We should continue to see Good to Moderate air quality through the rest of the work week.

Check out the latest webcam image at Pasayten Wilderness vs. that 24 hours ago. Noticeably less haze.

Wildfire smoke forecasts will become less frequent as conditions improve.
