Caltrans is alerting motorists about a late season storm in the Sacramento Valley and the Sierra Nevada that is expected to create some travel delays for the weekend.

The National Weather Service has issued a Winter Weather Advisory from 11 a.m. Saturday to 8 a.m. Sunday for areas above 5,000 feet.

Snow accumulation is forecast between 4 to 8 inches with localized amounts up to 1 foot over the highest peaks.

The heaviest snowfall is expected Saturday afternoon and evening with wind gusts up to 50 miles per hour.

Motorists should be prepared for travel delays, slippery roads, periods of reduced visibility and chain controls.

If motorists travel during the storm, Caltrans advises to have a full tank of gas or full electric charge and pack extra supplies in the event of an emergency or if traffic is held for an extended period of time. Those supplies should include snacks, water, blankets, and a flashlight.

In the Sacramento Valley, rain amounts are forecast between 0.5 and 1.5 inches. The highest amounts are anticipated near Chico, Marysville and into the foothills. Motorists should be prepared for periods of slick travel conditions.
