March 2026 was exceptionally sunny over most of the Alaska, Yukon Territory and NWT in ERA5 reanalysis courtesy @[email protected]. For much of central Alaska there was more sunshine than in any March since 1979. Graphic courtesy @[email protected]. #akwx #ytwx #ntwx #Climate

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

The 2025 wildfire season is about done in Alaska and the Yukon Territory, but is still going in the NWT. Seasonal review for northern North America wildfire now posted in the latest from the Alaska and Arctic Climate newsletter. #akwx #ytwx #ntwx #Canada alaskaclimate.substack.com/p/summer-202...

Northern North America wildfire area burned updated to Sunday. Area burned is higher than last year at this point in the season. Alaska has burned about 42 percent more area, Yukon Territory about 17 percent more and the Northwest Territories about 4 percent more. #akwx #ytwx #ntwx #Wildfire2025

Lightning sparked wildfires in the Northwest Territories: "…including one wildfire – named EV014 – some 40 km north of Inuvik, about as far north on the territorial mainland as such a fire has ever been recorded." #ntwx #Canada #Wildfire2025 cabinradio.ca/245848/news/...

Wildfire area burned in northern North America is ahead of this time in 2024. Largest increase is in the Yukon Territory. However, the last days of June 2024 saw rapid wildfire growth in Alaska and the YT, so this will look different at the end of the month. #akwx #ytwx #ntwx #Wildfire #Arctic

Wildfire area burned in northern North America is ahead of this time last sumner. Percentage-wise the biggest increase is in the Yukon Territory. However, in 2024 the last days of June saw rapid growth in wildfires in Alaska and the YT, so this will look different once June 2025 is complete. #akwx #ytwx #ntwx #Wildfire #Arctic

Alaska and vicinity comparison of April 15 snowpack snow water equivalent against same date last year. Much lower SWE southwest Alaska and lower Mackenzie valley. Much higher in the central Interior. Data from ERA5. #snow #Spring2025 #akwx #ytwx #ntwx @climatologist49.bsky.social
