Up to 162″ of snow (13.5-feet) is currently forecast to fall on 14,411-foot Mt. Rainer in Washington state in the next 3 days. That huge snowfall total is due to an atmospheric river that will be “slamming” into Washington this weekend.

“A pair of frontal systems with a significant tap of Pacific moisture will move through western Washington this weekend. They will bring heavy rain at times with the mountains receiving 4 to 8 inches of precipitation with locally higher amounts possible near Mount Rainier. Snow levels will remain high through Saturday before falling on Sunday as a cool upper level trough digs into the region. In addition to the precipitation, windy conditions at times are expected for much of the region.” – NOAA Seattle, WA
If you live in Washington, please be careful this weekend. NOAA has issued a flood watch as up to 8″ of rain are forecast for the next 3 days. Stay away from rivers and streams.
