Active Weather Pattern Continues for the Northwestern U.S.

A series of Pacific storm systems will bring periods of locally heavy rain, gusty winds, and mountain snow to portions of Washington and Oregon for the next couple days. In addition, much of the northwestern U.S. and Intermountain West will experience strong winds from these storm systems, particularly in Sierra Nevada, Great Basin, and the northern Rockies/High Plains.

Gusty southeast winds are expected to occur across portions of southern Oregon and northern California Saturday and Sunday. These winds will become strong along the coast, north-south oriented valleys west of the Cascades, the Shasta Valley, and the East Side. Travel on Interstate 5 as well as highways, 31, 39, 97, 101, 140, and 395 could become difficult—particularly for high profile vehicles. Remember to slow down and use extra caution when driving. Additionally, there may be isolated cases of downed trees or power lines. Loose objects may be blown away or damaged due to the winds. More information can be found on our detailed weather and hazards viewer.
The next system will be arriving to the Pacific Northwest this weekend. Although confidence is low on exact precipitation amounts, we are expecting precipitation most of the weekend. It will start out as rain, but change to snow over some of the higher passes on Sunday evening and night. This could bring accumulating snow to the higher passes like Siskiyou Summit at the CA/OR border and also near Black Butte Summit near Mount Shasta City. Stay tuned for more details regarding that storm! When driving in ice and snow, take it slow! Make sure to carry chains, food, water, blankets, flashlights, medications, and a fully charged phone when traveling.
