Rain will remain to the north of Los Angeles Monday, but clouds are expeced to roll in during the evening before rain and snow arrive Tuesday.
Winter weather advisories are in effect for much of Southern California. Winter storm warnings are in effect for Los Angeles, Riverside, Ventura and San Bernardino counties.
"It looks like the rain showers will intensify as we continue through Tuesday afternoon," said NBC4 forecaster Elita Loresca. "We have a chance for snow flurries in the Inland Empire. Snow will be heavy at times in mountain communities."
High wind warnings are in effect for Riverside and San Bernardino counties.
Snow might fall at elevations as low as 2,000 feet, Loresca added. The forecast prompted officials to close roads in Angeles National Forest, effective overnight Tuesday.
- Angeles Forest Highway from Aliso Canyon Road to Angeles Crest Highway (SR-2)
- Big Tujunga Canyon Road from Angeles Forest Highway to Vogel Flats
- Upper Big Tujunga Canyon Road from Angeles Forest Highway to Angeles Crest Highway (SR-2)
The closures will remain in effect until the storm moves out of the region and roads have been inspected, according to county officials.
High temperatures will reach the mid-50s in metro LA, valley areas and the coast Tuesday. Highs in the mid-30s are forecast for mountain areas.
