ESFSEW A series of atmospheric rivers will provide rounds of increasingly impactful rainfall starting on Friday and continuing through early next week. Snow levels will remain around 5000 to 6000 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.
The Whitewater River run begins upstream of the Diversion Dam (Rm 1) and flows for a total of 10.6 miles until it reaches the confluence with the Skagit River in the state of Washington.
