Heavy Snow in Petersburg Borough, Alaska

COOP station at the Petersburg Airport measured 6 inches of snow had fallen by 9pm on the 24th and another 8 inches by 830am on the 25th with snow continuing to fall. Another trained spotter in the area had around 12 inches storm total.

Low pressure lingered over the NE gulf with an associated front causing very light, dry snow to fall for over 12 hours. A wave formed along the front causing rates to pick up to warning level rates for another 12 or more hours, particularly on the northeast side of the low as it started tracking SE along the outer coast late on the 24th and into the 25th. The dry consistency of the snow lead to blowing snow and drifting as the front moved across the southern panhandle.
