A strong frontal system will move across south-central British
Columbia Tuesday night through Wednesday night bringing another
round of moderate to heavy rainfall to western Washington. Storm
total rainfall amounts of 3 to 5 inches are possible across the
Olympics and Cascades with 2 to 3 inches possible across the
lowlands. Snow levels will briefly rise from below 1000 feet on
Tuesday to just above 4000 feet on Wednesday, which will contribute
to greater runoff and snowmelt contributions, particularly over the
Olympics and central Cascades. This will lead to rapid rises in
river and streams across southwestern Washington, especially through
the Skokomish, Chehalis, Skookumchuck, and Newaukum River basins. At
this time, the Skokomish River near Potlatch is the only river
forecast to enter flood stage, though there is a 35% chance for the
Newaukum River near Chehalis to enter flood stage Thursday morning.
