system later Monday will result in heavy rain at times over the
area. Total precipitation amounts in the mountains will range from 3
to 5 inches, with locally heavier amounts possible in the mountain.
Snow levels will rise above 7000 feet, will result in snow melt at
low to mid elevations.

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.
