Smoke from (mainly) Northwest Territory, Canada wildfires will overspread most of the Yukon Territory and the eastern half of mainland Alaska today (Thursday) as winds aloft remain east to northeasterly. Graphic shows the forecast "Vertically Integrated Smoke" (how much smoke is in the air) for 4pm AKDT Thursday. @Climatologist49 @BakerRL75

Spring river break-up on the big rivers in Alaska and the Yukon Territory is under way. A little later than usual and so far, no major problems, though there's still a long way to go. Details and the climate context of this year’s break-up in the latest post from the Alaska and Arctic Climate newsletter. @Climatologist49

Seems unimportant in this moment, but if keeping up with environmental conditions in the North can bring you a calmer few minutes, here's an update on the status of the Arctic and Alaska and vicinity snowpack as of mid-January. @Climatologist49

Alaska and vicinity snowpack snow water equivalent as of mid-January is quite low relative to the 1991-2020 median over much of Southcentral and west/southwest Alaska. Exceptions though in the Kuskokwim delta and upper Bristol Bay. Southern Yukon Territory and northern British Columbia well above normal snowpack for this point in the season.

Wildfire area burned in the Northwest Territories, Canada has nearly doubled in the past two weeks, with more than 1.33 million hectares (3.30 million acres) burned in 2025. Although wildfire as been minimal in the Yukon Territory and Alaska this month, the northern North American total area burned is now nearly twice the 1988 to 2024 median and on par with 2022 and 2024. @Climatologist49

Smoke from wildfires evident in the available PM2.5 air quality reports in Alaska and the Yukon Territory Monday morning. AQI is significantly improved in the Fairbanks area but remains poor at Coldfoot and undoubtably much of the rest of the northern Interior. Unhealthy air quality in the Yukon is a combo of both local fires and transport from Alaska fires. Graphic courtesy PurpleAir. @anisian @Climatologist49

Sunday morning and wildfire smoke is degrading air quality though much of central and northern Interior Alaska, though obviously the lack of observations is an issue. Some of the smoke has worked up the Yukon River valley into the Yukon Territory, with reduced air quality at Dawson. Graphic courtesy PurpleAir. @anisian @Climatologist49
