A cold Pacific storm system is heading into Southern California and is expected to bring rain today to the Inland Empire with possible heavy snowfall in the local mountains.
The slow-moving storm is expected to arrive Monday and "bring the return of wintry weather to Southern California," according to the National Weather Service.
Showers and possible thunderstorms are expected to make Inland Empire freeways soggy for commuters making their return trips home.
A winter storm warning will be in effect for the mountains as moderate snow, to heavy at times, is anticipated today through Tuesday. Snow levels are expected to drop to between 4,000 and 4,500 feet today. Snow amounts may range from 12-20 inches.
Mountain travelers are warned that visibility could be reduced later today to a quarter-mile or less in heavy snow and fog. Beware of possible road closures, and chains may be required in heavy snowfalls.
The greatest snowfall amounts will be across the eastern San Bernardino mountains and southward across Mount San Jacinto, in Riverside County.
