Smoke Outlook for 7/20 – 7/21: Weather moderating in many areas, diminished levels of smoke anticipated

Temperature is moderating in many areas of Alaska including the Upper Yukon Zone. Wind gusts up to 30 mph in the Upper Yukon Zone is expected for today and will have an impact to fire activity. Smoke is forecasted to be in the unhealthy range once again, and residents are advised to take any steps necessary if health issues exist.

As weather moderates, fire activity is diminishing as well. Forecasted levels of smoke in various communities including the Kenai Peninsula, Juneau, and cities surrounding Fairbanks is expected to be less.

Fire

Swan Lake Fire is approximately 102,212 acres in size with 50% of the planned objectives accomplished. Fire was not as active as anticipated yesterday with precipitation falling on many active portions of the perimeter. Mild-moderate fire behavior is expected today depending on how far marine air makes it inland.

Smoke

Smoke production was not as much as anticipated yesterday, as the fire was less active than presumed. Less smoke impact is expected today as well. The western Kenai Peninsula experienced smoke from fires west of the Cook Inlet yesterday, which could happen again today.

Copper River and Juneau

Modeling shows smoke moving north this morning from the Copper River area fires, then shifting into the valley mid-afternoon. Smoke is expected to settle in thick overnight under a valley inversion, then mix out mid-day Sunday. Juneau should not be impacted by smoke.
