Big Wind AK

The winds over the weekend were certainly a nuisance. They made for sensitive wind slabs with whomphing and shooting cracks. Fortunately we managed the terrain well. Since the weekend the winds have picked up dramatically with insane gusts recorded at local weather stations. The winds have finally died down, but I expect people to find an entire new level of wind hammered.

Thompson Pass recorded a wind gust of 152 mph on November 16th at 1:21 AM. This weather station is on the road (not a ridge) and is 26 miles out of Valdez at 2,800'.

Not to be outdone, the Site Summit weather station above Arctic Valley just north of Anchorage had some impressive gusts of their own. This station sits on a ridge/mini summit at 3,924'.
