Rain to the rescue: Smoke in Vancouver and the Weekend Outlook

Smoke from the Camp Creek Fire is funneling into the Vancouver area this morning. Air quality monitors in Vancouver observed elevated concentrations of PM2.5 starting around 3am. Air quality should improve today with the rain, but the pattern may repeat itself tomorrow morning. The Southwest Clean Air Agency has issued an Air Pollution Advisory for Clark County today through tomorrow afternoon due to intermittent unhealthy smoke impacts.

As for the upcoming weekend, recent rain has moderated smoke production from local fires, and more rain is coming thanks to a new frontal system. Colder temperatures and more moisture bode well for decreasing fire potential from any new lightning starts. Check out the forecasted total precipitation for the region through Sunday evening:

Forecasted winds from the north Friday and into Saturday will transport Canadian smoke down into Okanogan Valley. The area may observe intermittent moderate air quality. Smoke from the Airplane Lake Fire is also causing moderate to unhealthy air quality in the Lake Wenatchee area, which may continue through the weekend before more rain arrives on Sunday. Other than that, minimal smoke impacts are expected throughout the state this weekend. For areas close to fires, check out the smoke outlooks tab for updates. Enjoy the (mostly) good air quality!
