Southern California is starting the week with fresh cold and the return of Santa Ana winds.
Fresh chilly air is sinking into Southern California in the wake of the storm that started the weekend with some rain and low-elevation snow.
The Grapevine section of Interstate 5 was among the lower elevations that had snow on Saturday. Enough snow fell that officials closed this section of the interstate, according to California's Department of Transportation.
Temperatures in Downtown Los Angeles dropped below 40 on Sunday night, making for the city's lowest temperature since February.
Temperatures barely climbed to 60 degrees on Monday, nearly 10 degrees below normal.
Monday was sunnier than the previous weekend days, but the gusty Santa Ana winds will start howling in the mountains and through the passes and canyons that surround Los Angeles.
Before the winds develop, it could turn cold enough for patchy frost in the valleys.
A moderate Santa Ana wind event will unfold through Tuesday morning with gusts of 50 to 60 mph expected in the populated areas. Stronger gusts will whip the mountains.
Such gusts could lead to power outages and tree damage. The winds also threaten to overturn high-profile vehicles, including those traveling on the I-5's Grapevine section and I-15's Cajon Pass.
The winds will help prevent temperatures from plummeting overnight on Monday, but the same cannot be said for places that are sheltered from the wind--such as Downtown Los Angeles.
On Monday night, Los Angeles will approach the daily record low of 36 F from 1951. Frost is possible in the city's colder wind-sheltered suburbs.
