Heavy Snow in City and Borough of Yakutat, Alaska

Periodic snow showers fell over Yakutat during the evening of the 14th, then rates increased and became steady after about 1am AKDT on the 15th. Visibility periodically fell to a quarter mile through the morning with around 7 inches of snowfall accumulation measured by 1pm when snow let up.

A trough of low pressure and mid level vorticity, plus cold air advection over the Gulf of Alaska caused a band of snow showers to set up along the NE gulf coast on Saturday 3/14. Intermittent snow showers occurred from Yakutat to Sitka, but showers moved out of Sitka and Pelican/Elfin Cove while rates picked up at Yakutat through the early morning hours of Sunday the 15th. A winter weather advisory was upgraded to a warning as visibility dropped to a quarter mile.
