Smoke Outlook for 7/22 – 7/23: cooler temperatures and higher humidity countered by strong winds

Gusting winds resulted in active fire behavior in the Upper Yukon Zone, but cooler temperatures allowed firefighters to make progress on other fires which produced less smoke.

Fire

Fire activity in the East Central Interior could increase with higher temperatures and drier conditions. Other parts of the state, including the Galena Zone and Upper Yukon Valley, continue to have hot dry conditions with intense fire activity.

Smoke

Fairbanks and North Pole can expect good to moderate air quality, with some smoke being transported in from surrounding areas. In areas with large, active fires such as the Upper Yukon Valley and the Galena Zone there may be smoke at unhealthy levels. Blue Sky computer modeling indicates good to moderate air quality in Denali National Park today.

Swan Lake Fire is approximately 102,027 acres in size (reduction in size due to more accurate mapping) with 50% of the planned objectives accomplished. Weather was not favorable for active fire yesterday, shifting winds could bring more activity today, though nothing notable is anticipated.


Smoke
Cooper Landing saw some relief yesterday, though the sensor reading shown below may not represent in town conditions. Anchorage experienced moderate air quality all day, this should improve once remaining smoke mixes out. Northwest winds are anticipated to bring smoke into Cooper Landing and possibly Seward.
