ESFSEW A series of strong and wet Pacific storm systems will track through western Washington next week with sharp rises on the rivers flowing off the Olympics and Cascades. There is little break between each system. As a result, several rivers are forecast to reach Action Stage with Minor flooding possible, especially by Wednesday or Thursday. Flooding extent will depend on rainfall rates, temperatures, snow levels, and total rainfall with each of these weather systems next week. Please monitor the latest river forecasts from the National Weather Service for additional information.
