Prolonged Atmospheric River Will Impact the Northwest Early this Week

A weather system in the Pacific Northwest will produce rain throughout the day, before a potent atmospheric river produces a prolonged round of heavy rainfall, widespread urban and river flooding, and high elevation snow to the region Monday through Wednesday. Showers and thunderstorms may produce isolated damaging winds, a brief tornado, and locally heavy rainfall across parts of Florida today. Read More >

Rainfall will continue through early this week with steadiest rainfall Monday night to Wednesday and across primarily NW sections of the forecast area. Coos and Douglas counties will be affected the most, but also Curry County. Since river levels are running very low for this time of year, the risk of flooding is very low, but there could be some ponding of water on roadways, especially north of North Bend.
Gusty winds are expected east of the Cascades in Oregon Monday night through Tuesday evening. Winds of 20-30 mph are expected with gusts up to 50 mph. Travel will be difficult, especially for high profile vehicles. Be sure to secure loose objects on you property.
