Powder Snow at Anchorage

January 2018

Snowfalls of six inches or more are not unusual during the winter in Anchorage: in the past decade, nearly two dozen days had that much snow. However, the 6.8" of snow that fell on January 23 was unusual because it melted down to only 0.18" of water, having a snow to liquid ratio of 38 to 1, a far cry from the often used (but often inappropriate) 10 to 1 rule of thumb. This ratio is among the highest of record for big snowfalls in Anchorage, effectively equaling the ratio of 7.8" of snow that melted down to 0.20" water on February 28, 2009.
