Winter Weather in Susitna Valley, Alaska

The Alaska Department of Transportation reported 18 inches of new snowfall that had fallen overnight near milepost 121 of the Parks Highway (northwest of Talkeetna) on the morning of 4/12. A spotter in Amber Lake also reported 10.5 inches of new snowfall during the same time frame.

Southerly flow moving into the Susitna Valley with an upper level trough helped support enough upslope enhancement into terrain with the background forcing and lift to generate moderate to heavy snowfall rates across northern parts of the region from the evening of 4/11 to the morning of 4/12. The highest new snowfall amounts of up to 1.5 feet were focused along the Parks Highway north of Talkeetna.
