The National Weather Service in San Diego has issued a Winter Storm Warning for snow and blowing snow, which is in effect from 4 a.m. Monday to 4 a.m. Tuesday. The Winter Storm Watch is no longer in effect.

A strong storm system will bring periods of moderate to heavy snow and gusty winds to the mountains of San Bernardino and Riverside counties from early Monday morning through Tuesday morning. Snow levels will rise to around 6000 feet during the day Monday and then lower to between 4000 and 4500 feet behind the front by Monday night. Snowfall accumulations of 1 to 2 feet are expected above 6000 feet in the San Bernardino and Riverside county mountains with local accumulations to 3 feet possible in the San Bernardino Mountains.

Local wind gusts in excess 45 miles per hour (mph) will cause blowing and drifting snow.

The combination of dense fog and blowing snow will reduce visibilities to less than one-quarter mile, making travel in the mountains hazardous.
