A strong frontal system will move across the area today and into tonight, bringing a round of moderate to heavy rainfall to western Washington and possible flooding. * WHAT...Flooding caused by excessive rainfall continues to be 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...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. - http://www.weather.gov/safety/flood
