Event narrative

Thompson Pass received 20 inches of new snow. Snow accumulated at a rate of 2 per hour between 10 am and 2:30 pm.

Wider weather episode

A low pressure system moving southeastward off the Kamchatka Peninsula rapidly intensified over the Bering Sea, reaching a central pressure of 944 mb by the time it crossed the Aleutian Islands. This system had a second, equally strong, low center that developed in its wake, continuing stormy conditions across the Aleutians as the first low moved onshore. The two low pressure systems brought widespread blizzards and high winds to the Aleutians, the Southwest Mainland, and Southcentral Alaska.
