A cold air mass behind a storm that has coursed though the Southland will generate frigid temperatures Tuesday morning, night and again Wednesday morning.
The warning applies to areas of Los Angeles, Ventura, Santa Barbara and San Luis Obispo County.
A freeze warning, which indicates impending temperatures of 29 and 32 degrees for two or more consecutive hours and is a small notch less serious than a hard-freeze warning, will be in effect until 9 a.m. in the Santa Monica Recreation Area.
A frost advisory will be in effect until 9 a.m. in the San Fernando and Santa Clarita valleys. Frost can damage plants and harm pets, just like more serious categories of cold-weather warnings.
No cold-weather warnings were in effect in the Antelope Valley this morning despite highs of 30. The warnings for the Antelope Valley are stopped after the first two in one year because the area is almost always frigid at this time of the year.
On Monday, the region also coped with strong winds, but the last L.A County wind advisory expired at 10 p.m. Monday. The storm, which was largely dry, had escaped to imperial County by early this morning.
Powerful wind gusts were recorded in Los Angeles County Monday, including 51 miles per hour at Lake Palmdale in the Antelope Valley, 49 mph in Warm Springs in the San Gabriel Mountains, 48 mph in parts of metropolitan Los Angeles, 43 mph at Whittier Hills in the San Gabriel Valley, and 42 mph in Glendale in the San Fernando Valley.
