...THREAT OF RIVER AND URBAN FLOODING SUNDAY THROUGH WEDNESDAY NEXT
WEEK ACROSS WESTERN WASHINGTON...
An period of active weather returns to Western Washington Thursday
and continues into next week as a series of frontal systems are
poised to move across the Pacific Northwest. Snow levels start off
between 1500 and 2000 feet on Thursday but rise closer to 6000 to
7000 feet by Sunday as deeper moisture advects over the region in
association with an atmospheric river. Total rainfall amounts
through Wednesday from these systems of several inches over the
lowlands to upwards of 10 inches or more in the Cascades and
Olympics will lead to rapid rises on rivers, especially combined
with melting as snow levels rise Sunday into the first half of next
week. River flooding will be possible on more susceptible rivers
such as the Skokomish River in Mason County, but may also include
other rivers in the Olympic and Cascade basins. Urban and nuisance
flooding may also occur during periods of higher rainfall rates,
especially Sunday into next week.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
