* 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, Clallam, Grays Harbor, Jefferson, Kitsap, Mason, Skagit and Whatcom. In west central Washington, King, Lewis, Pierce, Snohomish and Thurston. * WHEN...From 10 AM PST this morning through Thursday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Area creeks and streams are running high and could flood with more heavy rain. * ADDITIONAL DETAILS... - A series of weather systems this week will bring another round of significant rainfall to western Washington through Wednesday. Preliminary liquid totals of 2 to 6 inches, locally higher in some spots, will cause additional sharp rises to area rivers. Urban and small stream flooding remains possible for areas with poor drainage. Very saturated soils will maintain increased risk for potential landslides and debris flows off of burn scars. - Http://www.weather.gov/safety/flood
