A Winter Storm Warning remains in effect until 10 p.m. for the central Puget Sound region Monday as lowland areas saw significant accumulation during the day. 

Few schools in Western Washington decided to stay open Monday. Around 100,000 power customers in Western Washington lost power. Dozens of flights at Sea-Tac Airport were canceled due to icing concerns.

Lowland snow continued to fall Monday morning, but the steady snow tapered to rain/snow showers in the afternoon and evening. There was only minor additional accumulation.

WATCH: Snow a factor on the roads

The good news is the bulk of the accumulating snow is done, although some weak convergence may continue to give the Central Sound some additional light snow.

The bad news is the roads will be left wet overnight and are likely to freeze, leading to an icy Tuesday morning commute.



Pass conditions: Make sure you check pass conditions before venturing into the mountains. Both directions of Interstate 90 over Snoqualmie Pass were closed for most of the morning and have since reopened. The Cascades will likely see an additional 3-6 inches overnight. Traction requirements vary at the other passes, with some requiring chains. Check: Pass Reports

The precipitation will dry out Tuesday, giving way to more rain Wednesday.
