After warm and wild winds, weather will cool for Southern California
Cooler temperatures will start to return and Santa Ana winds will back off Tuesday as a weather system that rushed air from the desert to the ocean begins to fade, forecasters said Monday.
The northeasterly winds “should continue to weaken — it will be a little breezy Tuesday morning, but not nearly as strong as Monday, and by Tuesday afternoon it should be over with,” said National Weather Service meteorologist Stefanie Sullivan of the agency’s San Diego office.
For the Los Angeles area, winds will remain strong Tuesday morning, but also recede as the day goes on, said meteorologist Lisa Phillips of the NWS’s Los Angeles-Oxnard office.
High wind warnings issued for areas of Southern California were demoted to advisories by Monday afternoon, and the last of those will end Tuesday morning.
Monday morning, the winds were responsible for pushing over a trailer and leaving the truck towing it facing the wrong way on the southbound 15 Freeway north of Duncan Canyon Road, the California Highway Patrol confirmed.

No injuries were reported from the 8:41 a.m. incident just south of the San Bernardino Mountains foothills and northeast of Rancho Cucamonga.
Moving into Southern California will be a weak low pressure system from the north that will bring cooler temperatures, but not much moisture, because it will follow an “inside slider” pattern. That moves mostly over land rather than water, and doesn’t bring a lot of moisture with it, Phillips said.
If there is any precipitation in the coming days, it will be confined Thursday in Los Angeles County to possible snow in the mountains and rain for the Santa Clarita and San Fernando valleys, Phillips said, with no rain expected for the Los Angeles metro area.
For the Inland and Orange County areas, there may be a slight chance of showers on Thursday, Sullivan said, along with the return of a marine cloud layer Wednesday that will push farther inland as the week moves along.
Monday temperatures reached the mid-to-high 70s in many areas, and even the low ’80s in Orange County, the NWS said.
“Monday was the warmest day for the system — it will be a little cooler Tuesday and significantly cooler Wednesday,” Phillips said.
On Tuesday, the high forecast for Los Angeles is 77, but the Wednesday high will be 67; for Santa Ana the high will be 74 Tuesday and 65 Wednesday; San Bernardino and Riverside both will have highs of 74 Tuesday and 64 on Wednesday.
