ESFSEW
A late season atmospheric river will bring moderate to heavy
precipitation from Sunday afternoon through Tuesday across all of
western Washington. Heavy rainfall rates are possible over the
southwest Olympics, and the Cascades. Total rainfall amounts will
range from 1 to 2 inches in the lowlands, and 2 to 4 inches in the
mountains. Snow levels above 5000 feet will result in most
precipitation falling as rain. This will result in rivers running
unusually high, with the Skagit, Snohomish, Skykomish, White, and
Skokomish Rivers potentially over action stage. The Snoqualmie River
potentially will reach minor flood stage. This may impact any use of
the river flood planes that are normally dry this time of year.
Rivers will crest sometime between Sunday and Tuesday.
The next update will be provided Friday afternoon.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
