October is the fastest warming month over much of the Arctic due to the loss of autumn sea ice, and that's driving changes in precipitation and snow. I take a look at these changes in the latest edition of the Alaska and Arctic Climate Newsletter.

High temperatures in and around Alaska on Saturday. Most areas near to a bit cooler than normal except for parts of the North Slope and Southeast. Still warm in the southern Yukon and NW British Columbia. #akwx #weather

Arctic sea ice is melting rapidly, as happens this time of year. Details in my latest Alaska and Arctic Climate newsletter. #akwx #Arctic #SeaIce #Climate

I muted the word "convention" for a week and my blood pressure is much better for it.

The sea ice extent in the Chukchi Sea remains quite high for this point in the season, about 15 percent above the 1991-2020 median. Open water path now in place Bering Strait to Pt Barrow but northeast Chukotka coast remains iced in. Based on NSIDC data, extent is the highest for July 13th since 2000. Some open water starting to show up along the Alaska Beaufort Sea coast. #akwx #Arctic #SeaIce

High temperatures in and around Alaska on Thursday. The same weather pattern bringing cooler temperatures and rain to northern Alaska is responsible for the exceptionally mild weather in the Aleutians. #akwx #weather

May 2024 temperature departures from 1991-2020 normal around the Arctic show a coherent pattern with three main areas of above normal temperatures and three areas of below normal. The warmth in the Nordic Arctic and parts of Canada was notable, while SW Greenland and the western Russian Arctic were notably cool. For the #Arctic overall (land & sea poleward of 60ºN), the May average temperature was 0.4ºC above normal but the coolest May since 2018. #Climate #Canada #Spring2024 @Climatologist49

Arctic 12-month running temperatures as the difference from the 1951-80 average, updated through April 2024. The 10-year smoothed average shows the long term trend, the 2-year average captures some of the short term variability. OISSTv2.1 courtesy of NOAA/PSL/ESRL

And there it is: green-up on West Chena Ridge in Fairbanks, four days earlier than the 50 year median, and first "earlier than median" green-up since 2019. #akwx #ClimateDiary #Alaska #Spring2024 #Phenology

Here's an oldie but a goodie from @Climatologist49: for North America the time of the earliest sunset of the year. The effects of time zones are obvious.

Terrible situation in Wrangell, #Alaska from landslides due to heavy rain. KSTK radio reporting:
"An undisclosed number of people are missing after a “massive” landslide destroyed at least two houses…about 11 miles outside of Wrangell late Monday night…initial measurements show the slide…stretches from the uplands to the saltwater."

There were also landslides on Prince of Wales Island blocking roads.

How "over the top" is this year's #wildfire season across #Canada? The 13.7 million hectares burned (thus far) is seven times the 1980-22 median and is 56 percent higher than the previous highest seasonal total (1989)! That's WAAAY over the top.
