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.
