Weekend Cascades Snowfall

Active weather continues to produce hazardous coastal conditions through this weekend. A series of storms will bring gusty south winds and hazardous seas Thursday through Sunday. These storms will be accompanied by multiple long period W to NW swells of 15-22 feet from Thursday afternoon through Sunday, resulting in hazardous breaking waves of 20-28 feet in the surf zone. There will be a high risk for sneaker waves during any brief lulls between periods of high surf. Waves could wash over rocks/jetties and into normally dry areas. Beach erosion is possible. Please use extra caution if you plan to visit the beaches this weekend.

Plenty of afternoon sunshine is in store for this week, though with cloudy mornings to start in some West Side Valleys. Mornings will be on the chilly side as well with afternoon temperatures warming to a few degrees above normal through Thursday. Afternoon temperatures trend cooler for Friday and Saturday as the pattern transitions to cool, wet and windy. A front will move onshore Friday, bringing widespread rainfall and high elevation snow. Snow levels will hover around 6000-7000 ft on Friday, lowering to around 4500 ft late Saturday into Sunday.

A pattern change will bring active weather starting on Friday and continuing through the weekend could create a number of dangerous conditions across northern California and southern Oregon. Gusty winds in coastal areas, in the Shasta Valley, and east of the Cascades could lift and carry light objects or push high profile vehicles. Moderate to heavy rainfall may lower visibilities or create urban ponding. Snowfall over the Cascades will make hazardous travel conditions. Freezing temperatures east of the Cascades will refreeze water on surfaces and could affect infrastructure, plants, and animals.

Decreasing snow levels and constant precipitation will bring accumulating snowfall over the Cascades through the weekend. While snow showers could start early Saturday morning, rates pick up in the afternoon and continue at about 0.5 inches per hour through Sunday. This could bring 12 to 18 inches of snowfall through the weekend. These amounts pose a number of threats to anyone traveling over the Cascades through the weekend. Slush or accumulated snow can make travel along highways dangerous, and snow over terrain can add another risk to offroad travel. Freezing temperatures overnight can freeze water or wet snow and create slippery conditions. Please take the proper preventative actions if travel is necessary.
