A flood watch is in effect through Monday for Western Washington. There is also a wind advisory for the Coast and central Puget Sound region. Forecasters are saying “excessive rainfall for late September” is expected this weekend with total amounts of 4 to 8 inches (up to 10 inches in some areas) predicted in the mountain. The heaviest rain is expected on the southwest facing slopes. This amount of rain will drive some rivers near or slightly above flood stage. The Skokomish River is “most likely” to experience minor flooding this weekend. The Skokomish is expected to reach about 15.5 feet Saturday night, then drop under 15 feet before rising again to near 16 feet Sunday night. However, the latest predictions show the River should NOT reach the 16.5 foot flood stage before beginning to recede.
The heavy rain could also result in minor urban and small stream flooding. Storm drains should be checked to ensure they are not clogged with debris. And ponding on area roadways is also a possibility. There is 100% chance of rain through Sunday night with the rain tapering off through next week.
Gusty south winds upt to 50 MPH are also possible through Sunday night mostly on the Coast. But winds this strong can snap small tree branches, topple small or shallow rooted trees and cause local power outages.
