Heavy Snow — Eastern Chichagof Island, Alaska

2023-02-24 to 2023-02-25 · Eastern Chichagof Island, Alaska

Event narrative

Hoonah COOP measured a storm total of 9.1 inches with most of that falling in the latter 12 hours of the long duration event. Snow was dry and blowing around, which may have reduced the overall total.

Wider weather episode

Low pressure lingered over the NE gulf with an associated front causing very light, dry snow to fall for over 12 hours. A wave formed along the front causing rates to pick up to warning level rates for another 12 or more hours, particularly on the northeast side of the low as it started tracking SE along the outer coast late on the 24th and into the 25th. The dry consistency of the snow lead to blowing snow and drifting as the front moved across the southern panhandle.
