ESFSEW
A series of storm systems will spread moderate to heavy rainfall
across Western Washington through early next week. Rainfall will be
heaviest across the Olympic Peninsula, with total rainfall amounts
of two to five inches expected. The snow levels will generally
remain near 2500 or 3000 feet, which may limit runoff. This amount
of prolonged rainfall has the potential to push the Skokomish River
into flood stage by Monday evening.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
