Across the Northwest (including Washington & Oregon):
Already battered by back-to-back atmospheric rivers, the Northwest has experienced very heavy rain and snow. More is on the way. Another powerful storm system is set to slam into the region by Saturday morning, bringing very heavy rain, mountain snow, and gusty south winds. This weather is expected to persist through Monday before diminishing. A small break is expected with more mild conditions followed after before another active period.
Cities to be Impacted:
WA: Seattle, Bellingham, Spokane and Yakima.
OR: Portland, Bend, and Eugene.
Forecast Details:
A powerful system is expected to arrive by Saturday around noon. This system is forecast to bring another round of heavy rain, mountain snow, and gusty winds. Rainfall is projected to be around 1 inch north of Seattle and 2-4 inches along the coast from Washington down through Oregon. Although these totals are lower than those from our previous back-to-back storm systems, it won’t take much to cause flooding, including river flooding and other issues across the area. Rivers are expected to potentially rise again, reaching action stage, especially with the combination of mixed precipitation in the mountains. There is also a risk of freezing rain due to the lower snow levels in the mountains. The front is anticipated to move out of the area by Monday, but lingering showers are expected due to the amount of moisture in the air.
Approximate Rainfall Totals:
Main risk: heavy rain leading to flooding, heavy snow and mixed precipitation across the mountains and gusty winds.
Stay tuned for more updates.
