Hydrologic Outlook issued February 20 at 3:09PM PST by NWS Seattle WA
ESFSEW
A series of storms will begin to impact western Washington on Friday and continue through Tuesday. The next storm on Saturday will have heavy rain at times as will a third storm right on its heels Sunday.
Precipitation amounts could be 3 to 8 inches storm total with snow levels rising above 6000 feet. With moderate temperatures now and warmer temperatures to come, this will also result in a some snow melt at low to mid elevations. These factors will combine to result in a potential for river flooding. At this time the most likely flood severity will be minor flooding. There is also a Flood Watch out for Mason County, including the potential for moderate flooding on the Skokomish River.
The most likely areas for river flooding will be for rivers flowing off of the central and southern Washington Cascades, the Olympics, and in southwest Washington. Urban and small stream nuisance flooding and rainfall-induced shallow landslides will also be possible.
Please monitor the latest river forecasts from the National Weather Service for additional information.
