A Winter Storm Warning is in effect for the Cascades of Whatcom, Skagit, Snohomish and King counties through midnight tonight. Heavy snow in the Cascades could add to travel times. Forecasters are predicting 1 to 2 feet of new snow, with the heaviest amounts from Mount Baker to Stevens Pass.
The National Weather Services in Seattle and Portland have also issued a Coastal Flood Advisory for the central and south Washington coast in Grays Harbor and Pacific counties from noon until 4 pm this afternoon.
In both cases, the predicted high tide today will add to the tidal anomaly created by atmospheric pressure and wind, and be about 2 and a half inches above the value where flooding begins.
Minor tidal overflow may produce some flooding along the shoreline. Waves up to 10 feet breaking on beaches could carry debris like logs further inland.
Overflow flooding for the South Washington coast is most likely to occur in low-lying areas near bays and sloughs, highways 6 and 101, and in the towns of Raymond and South Beach.
