Caltrans is alerting motorists that the National Weather Service has issued a Winter Storm Watch in the Northern California area for Wednesday through Friday. The storm is forecast to include heavy valley rains, high winds and up to 12 inches of snowfall at the higher elevations, including Donner and Echo Summit passes.

As winter driving conditions develop, chain controls on Interstate 80 over Donner Summit and on U.S. Highway 50 over Echo Summit should be anticipated. High winds may create white-out, low visibility conditions over the summits. Heavy rains in valley and foothill areas will result in wet, slippery surfaces and potential roadway flooding.

Caltransa snow removal crews will be working throughout the storm on summit passes and impacted Caltrans roadways. Caltrans permitted and trained chain installers on I-80 can be identified by a reflective sign with their bib number. Valley area crews will be monitoring roadway drainage systems and motorists are advised that detours resulting from flooded roadways should be anticipated.

Severe weather may slow motorists, resulting in roadway congestion. Wet and slippery roadways reduce tire traction, especially at high vehicle speeds. Hydroplaning can result in loss of driver control. Motorists are encouraged to slow down and observe the following winter driving tips, which can also be found at
