Winter Storm — Eastern Chichagof Island, Alaska

2017-03-02 to 2017-03-03 · Eastern Chichagof Island, Alaska

Event narrative

There were 8.8 inches of new snowfall in 6 hours. This is quite a high rate. Snowfall lingered into 3/3 but not at that rate. Impact was snow removal for Hoonah and Tenakee Springs. Storm total at Tenakee was 10 inches.

Wider weather episode

Arctic high pressure persisted over the Yukon on the night of 3/1 as a storm force low moved northward into the eastern Gulf of Alaska. This set up warm moist air overrunning the colder air at the surface causing heavy snowfall to the Northern Panhandle almost immediately following a previous snow dump 2/28-3/1. No damage was reported, but again the impact was snow removal on top of a large snowpack.
