Atmospheric river impacting northern, central California
A winter storm warning as well as a flood watch have been issued for parts of northern and central California, closing numerous roads throughout the region.
Heavy mountain snow and rain at lower elevations is the result of a prolonged atmospheric river event, the National Weather Service in Sacramento said.
The National Weather Service is forecasting rain and/or snow for parts of northern and central California through Friday, Feb. 7. As much as 6 inches of precipitation was in that forecast.
Traffic information from California and across the country can be found on this Land Line resources page.
Additionally, in Mendocino County, U.S. Highway 101 was temporarily down to one lane of traffic due to a landslide.
Avalanches are also a concern in the Greater Lake Tahoe area, where the National Weather Service in Reno has issued winter storm and avalanche watches through Wednesday morning, Feb. 5. Travel throughout the Sierra Nevada mountains is expected to be impossible later this week.
The state’s chain laws were in place as of Tuesday morning, Feb. 4, with Caltrans advising against mountain travel.
