A strong frontal system will move across the area Tuesday night

rainfall to western Washington and possible flooding.
* WHAT...Flooding caused by excessive rainfall is possible.
* WHERE...Portions of northwest and west central Washington,
including the following counties, in northwest Washington, Grays
Harbor and Mason. In west central Washington, King, Lewis, Pierce
and Thurston.
* WHEN...From late tonight through Thursday afternoon.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
* ADDITIONAL DETAILS...
- A rising snow level, moderate to heavy rain, and to a lesser
degree low- to mid-elevation snowmelt will potentially
produce enough runoff to cause minor flooding of some streams
and rivers. The Olympics and Cascades could see 3 to 5 inches
of rain. The snow level will rise Wednesday to 4500 feet.
Based on the degree of snow level changes, it's relation to
precipitation, and the amount of precipitation and snowmelt
makes for a fair amount of uncertainty on what, if any,
rivers will flood. The exception is the Skokomish River which
is highly likely to exceed flood stage and possibly Moderate
Flood.
