Blizzard in Yukon Delta, Alaska

A low pressure center around 940 mb tracked slowly east across the central Bering Sea on the 17th through 19th. The associated occluded front moved over the Yukon Delta late on the 18th and 19th. In advance of the front blizzard conditions likely occurred at Marshall for about 4 hours during the afternoon of the 18th, where the visibility dropped to one-quarter mile or less, likely due to blowing snow, with winds speeds 40 to 45 mph. Other reporting stations showed slightly lower wind speeds and visibilities were not as severely reduced.
