Seattle Breaking Its Single Day Rainfall Record Is Kind Of A Big Deal

Unless you were born under a rock, you know Seattle sees its fair share of rainy days. On average the city sees roughly 150 days of rain each year, which is more than any city east of the Rockies.

So when they break their single day rainfall record you take notice. The new record broke the previous by only .01″. The new record is 1.20″ of rain in a single day. If that precip were to fall as snow at 30°F, it would roughly amount to 1-2 feet of new snow (*depending on density).

The previous record of 1.19″ was set in 1958.

All this moisture is also set to impact the mountains where Mount Baker and Mount Rainier should both see over 10 FEET of new snow near their summits.
