How to Read Our Snow Data Above
Snowfall amounts for 12hr (overnight), 24hr, and 48hr timeframes are based on measurements taken at 5am daily. 24hr and 48hr snow totals are cumulative, so whatever fell in the last 24 is built into the 48. Between 5pm and 5am our weather data is automatically updated based on telemetry data from Northwest Weather and Avalanche Center and represents our overnight totals. The "Since 5am" snowfall amount is based on manual measurements taken periodically throughout the day.

As of April 5th, the top of Alpental has received 610" of snowfall. The first significant snowfall of the season up there was 9" on November 2nd. It's interesting to note that normally we see several substantial storms in April that help carry the lower mountain thru into early May, while this year we have seen only two snow events which delivered less than an inch.
Always remember to check the WSDOT for information about summer construction over Snoqualmie Pass and how that may impact your travel plans.
