...THREAT OF RIVER FLOODING ACROSS WESTERN WASHINGTON NEXT WEEK...

A series of atmospheric rivers will provide rounds of increasingly
impactful rainfall starting today and continuing through next week.
Snow levels will fluctuate around 4500 to 6500 feet. Expect rising
rivers with potential for flooding especially for rivers flowing off
the Olympics and Cascades. Urban flooding and landslides are also
possible throughout this period as the soil conditions remain wet.
