Storm Watch: Flooding, snow cause road closures through Sacramento, Sierra regions

A Winter Storm Warning began Friday night and will continue through early Monday. A Flood Advisory was issued Saturday morning and remained in place until 9:30 p.m.

CALIFORNIA, USA — Scattered rain and snow showers are forecast to continue through Sunday. Snow in the mountains will continue to fall and officials are discouraging unnecessary mountain travel.

Forecasts say some cities could see minor flooding in low-lying and poor drainage areas. Ponding on some roadways and in parking lots is likely. Officials advise drivers to never go through floodwaters.

Rain and snow returned to Northern California this weekend. A Winter Storm Warning began Friday night at 10 p.m. and will continue through early Monday morning at 4 a.m.

In the Valley, heavy rain is expected through at least the early afternoon with heavy snow and travel delays expected in the Sierra. One to two inches of rain in the Valley is forecasted and more in some spots. 

As much as 2-6 feet of snow could fall in the Sierra with localized higher amounts. Blowing snow will significantly reduce visibility in the Sierra, creating even more dangerous driving conditions.

Wind gusts up to 50 mph are expected in the Valley and will cause debris to move around. Winds could be strong enough for tree limbs and some trees to break.

Road Conditions

Snow in the mountains Saturday will impact commute times as roads will be slick. Drivers on I-80 or US-50 should be prepared for chain controls in the Sierra. Officials are expecting conditions to continue to get worse overnight. Drivers on I-5 and in the Valley should increase the following distance and reduce speeds to account for rain.

Interstate 80

Caltrans advises not to travel on I-80 unless absolutely necessary.

  • Both directions from Drum Forebay to Truckee: Chain controls are in effect for all vehicles except four-wheel/all-wheel drive or with snow tires on all wheels, according to Caltrans.
  • Interstate 80, Nevada state line: I-80 westbound from the state line is closed and eastbound at Colfax, according to Caltrans. Only Truckee residents are allowed to and from Reno at this time and there is no estimated time of reopening.

Highway 50

  • Meyers to Kyburz closed: Roads are being temporarily closed for avalanche control, according to Caltrans. There is currently no estimated time of reopening.
  • Twin Bridges to Meyers: Chain controls are in effect for all vehicles except four-wheel/all-wheel drive or with snow tires on all wheels, according to Caltrans.

State Route 88

  • SR-88 is closed from Caron Pass to Red Lake: The road has been closed due to zero-visibility and there is no estimated time of reopening, according to Caltrans.
