Smoke Outlook 7/29-7/30; Air quality improving, but smoke not gone over central Interior

While recent weather conditions have decreased smoke in most areas, warmer weather and persistent drought may cause an increase in fire activity over the next few days. Light haze may also develop over Juneau from fires in Canada, but air quality will remain good there.

North (Fairbanks, Denali National Park, Upper Yukon)

Map shows multiple active fires in central Alaska around Fairbanks and North Pole, and poor air quality in For Yukon.

Fire

Drought conditions persist across the central interior, despite recent precipitation. With warmer, drier weather expected over the next few days, fire activity could pick up across the zone. Fires remain active in the Upper Yukon Valley where little precipitation has been received.

Smoke

The Tanana Valley is expected to have good air quality today. Fairbanks and North Pole may see very light haze tomorrow. Air quality is expected to be good in Denali National Park today and tomorrow. In the Yukon Flats, light variable winds are expected today. Air quality will be poorest in the vicinity of the active Chalkyitsik Complex fires. While air quality has generally improved in Fort Yukon, it is still expected to be moderate to unhealthy at times as variable winds carry the smoke in and out of that community. If you begin to notice health effects from smoke, you are encouraged to follow the “actions to protect yourself” listed below.

South (Anchorage, Kenai Peninsula, Cooper Landing)

Fire

Fire activity on the Swan Lake Fire is minimal, due to widespread rain over the fire this past week. Drought conditions are still high in parts of the Kenai Peninsula and the Mat-Su Valley, and with several days of warm, dry weather, the possibility exists that fire activity could pick up.

Smoke

There are no expected smoke impacts in this area from the Swan Lake Fire or from fires to the north.

Copper River and Juneau

Models show that there is a possibility of light haze in Juneau from fires in Canada, but overall, air quality should be good.
