For anyone venturing into the Turnagain area mountains, wind slab avalanches are what to watch for. Despite the strong northwesterly winds during the last 24 hours, which did a number around Turnagain Arm, there is still plenty of loose snow available to blow around. This can be attested to by the lack of wind damage above 3300ft on Tincan today. The wind slabs I did see were at the mid elevations, very stiff and cracking just around my feet. However, they were sitting on faceted snow and though I didn’t find any in the few starting zones I was able to get to, I’d keep a look out for them. Winds are forecast to continue over the weekend from the north and northeast. Below is a picture of the mid elevation wind damage:
This past week most of Alaska’s wet weather has been just to our north. The temperatures did climb mid-week, up to 32F at 2,500′, but are on their way back down to the teens now. The last 24 hour winds have been moderate to strong from the northwest. These should continue to be moderate with strong gusts from the north and east for the next several days or more. This will do a good job of ushering in the cold temperatures that are on tap. Our next chance for snow is not in the foreseeable future.
The National Weather Service in Anchorage has done a great job at summing up the weather for next week:
