Anchorage sets new records with unusual weather
The September storm that brought rain and snow to Southcentral Alaska is one for the record books.
Things got interesting on Tuesday, Sept. 29, when a strong storm system dropped 1.56 inches of rain in Anchorage. This beat the old daily record of 1.21 inches set in 1961.
Area flood advisories were issued for the Anchorage area and the Susitna Valley. Many streets and low-lying areas experienced standing water and flooding. In total, Anchorage recorded 7.7 inches of precipitation for September, which accounts for half of the total precipitation so far in 2015. This makes September 2015 the wettest on record for Anchorage.
Wet snow began mixing in with the rain in most areas of the Anchorage bowl by Tuesday afternoon, and Anchorage recorded its first official snowfall of the season by 10 p.m. To be considered the “official” first snowfall, 0.1 inches of snow must be recorded at the National Weather Service office in Anchorage at Sand Lake.
Most of the snow, however, fell in the early morning hours of Wednesday, Sept. 30. Snowfall totals for the event ranged from 2-5 inches in the bowl, with amounts of 6-8 inches recorded on the hillside. In the Matanuska and Susitna Valleys, totals between 1-3 inches were recorded.
The September snowfall is sixth earliest on record for Anchorage. Snowfall totals were also higher than usual — Anchorage doesn’t usually receive 1 inch of snowfall until around Oct. 22.
