Hydrologic Outlook issued February 21 at 11:55AM 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 5 inches storm total with
locally heavier amounts, and snow levels rising above 7000 feet.
With moderate temperatures now and warmer temperatures to come, this
will also result in some snow melt at low to mid elevations. These
factors will combine to result in a potential for river flooding.

The most likely areas for river flooding will be for rivers flowing
off of the Cascades and Olympics. 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.
