Snow began late on February 28th and became heavy through the following morning with periodic gusts of around 30mph. A change to rain happened in the late morning. A trained spotter south of Wrangell measured 6 inches of dense snow.

Wider weather episode

A strong low pressure developed over the northern Gulf of Alaska bringing significant moisture to Southeast Alaska. Cold air entrenched over the region at low levels ahead of the event allowed for significant snow to fall across the area in two major pulses. The first being along the warm front, with a period of blizzard conditions over Juneau, and the second pulse occurred as the cold front moved across the region.
