MARYSVILLE – Another weather system delivering snow to the Sierra and rain to the valley is expected this week, according to the National Weather Service.
Arriving Monday night, a wet weather system is expected to deliver another 12-18 inches of snow at Donner Pass on Interstate 80, and 8-12 inches at Echo Summit on U.S. Highway 50. Snow levels will begin at 5,000-6,000 feet before dropping to 4,000-4,500 feet by Tuesday. Sierra travel is anticipated to be most impacted Tuesday with caution advised when traveling in the mountains.
The valley and foothill areas are also expected to see more rain between Monday and Wednesday this week: 1-2 inches in Chico, 0.5-1 inch in Sacramento and 2-3 inches in Grass Valley. Motorists are advised to be alert for slick roads or roadway ponding.
Caltrans reminds drivers to winterize vehicles by ensuring tires are properly inflated and have good tread, and to stock up with water, blankets, snacks, a flashlight and a full tank of gas before mountain travel. Further tips for safe winter driving and information about chain controls can be found at dot.ca.gov/travel/winter-driving-tips.
Motorists also are reminded to carry traction-control devices in their vehicles as permitted highway chain installers do not sell traction devices. Periods of chain control are anticipated during both storms with posted speed limits of 30 mph on Interstate 80 and 25 mph on U.S. Highway 50 during chain-enforcement periods.
