Smoke outlook for 7/23 – 7/24: unhealthy air in some areas as smoke returns across Alaska

Map showing North Alaska fires and smoke impacts to Fairbanks, North Pole, and Fort Yukon on July 23, 2019.
Smoke from wildfires moderately impacting Fairbanks and North Pole, with unhealthy impacts to Fort Yukon.

Heavier smoke returns to the Upper Yukon Valley and will primarily be moving south and west today, both from the large complex fires, as well as from the fires closer to Fairbanks and Denali.

Some local areas will experience unhealthy conditions, especially in the mornings, including including Rampart, Fort Yukon, and parts of Denali National Park. Air quality in Fairbanks, North Pole, Denali National Park, and Anchorage will be moderate overall.

Residents and visitors should take appropriate steps to protect themselves in areas where they are being impacted by smoke.

North (Fairbanks and surrounding cities, Denali National Park)


Fire behavior in the Upper Yukon Valley is expected to remain active with continued high temperatures and dry conditions. Weather in the east central zone is also warmer and drier, but fire activity has moderated somewhat there.

With calmer wind conditions expected, there will be heavier smoke concentrations across the zone, especially in the morning. Air quality will moderate as the smoke becomes more widely dispersed as light variable winds. Fairbanks and North Pole can expect moderate to USG air quality , with smoke more concentrated in the morning and moving in again overnight. Blue Sky widespread smoke in Denali National Park over the next couple of days. Air quality is expected to be moderate, with periods of USG or even unhealthy in localized areas there as well.

Smoke from the Swan Lake Fire is drifting north, while air quality in Seward remains good.


Swan Lake Fire is approximately 102,227 acres in size with 72% of the planned objectives accomplished. The fire was active on the eastern flank yesterday in Mystery Creek drainage. Clearer and warmer conditions today could result in increased fire behavior. Showers possible overnight could lesser fire behavior tomorrow.


Cooper Landing has and will continue to experience smoke, heavier on the western side of the community. Anchorage experienced moderate air quality all day yesterday, this is expected to continue.
