Weather forecasters issued a "freeze watch" on Saturday for high-desert areas as sub-freezing temperatures grip Southern California.
Temperatures were expected to drop as low as 23 degrees for possibly up to six hours overnight Saturday and into Sunday morning, forecasters said.
Meanwhile, in Wrightwood, the Mountain High ski resort was making its own snow in preparation for a Sunday opening. Snowboarders and skiers were already in line for season passes Saturday.
The frigid temps and wind gusts up to 55 mph in the Antelope Valley prompted officials to urge residents to bring pets and plants inside their homes and urged motorists in high-profile vehicles to drive with caution.
Temperatures in the L.A. area and vicinity were expected to reach the low to mid 60s with night-time temperatures dropping to the 40s.
Highs on Sunday are expected to be in the mid 60s to lower 70s and lows will be in the mid 40s to lower 50s.
There's a slight chance of rain and possibly up to an inch of snow possible, mainly on the northern slopes at elevation levels between 3,500 to 4,000 feet, forecasters said.
High temperatures in the mountains will range from the upper 40s and 50s at low elevations to the lower to mid 30s at higher elevations.
Officials were warning residents of high rip currents and waves up to 5 feet on some west-facing beaches.
