Santa Ana winds to bring cooler weather to Inland regions, higher temperatures along coasts – Daily News

0

Dry Santa Ana winds forecast to whip through portions of Orange, Los Angeles, Riverside and San Bernardino counties beginning  Monday, Dec. 16, will bring cooler-than-average temperatures to Inland regions, but warmer weather along the coasts at the start of the week.

Weather patterns were predicted to shift overnight Sunday, resulting in powerful offshore gusts over the following two days, the National Weather Service reported. Gusts could hit 55 mph, prompting authorities to issue a high wind advisory effective between 10 a.m. Monday and 10 p.m. Tuesday in Orange, San Bernardino, Riverside and San Diego counties.

During that time, similar conditions were expected in wind-prone areas of Los Angeles and Ventura counties.

Authorities asked people to be on the lookout for downed power lines and urged motorists, especially those driving high-profile vehicles that might possibly tip over, to drive cautiously.

The strongest winds will be confined to the Cajon Pass in San Bernardino County, the San Gorgonio pass in Riverside County and the Interstate 8 corridor in San Diego County on Monday.  By Tuesday, gusts should approach 50 mph in areas west of the Santa Ana Mountains like Irvine; and northern portions of Los Angeles County like Simi Valley and Santa Clarita.

Skies should remain clear, but the offshore weather system developing at the start of the week will bring temperatures 2 to 5 degrees cooler than average for this time of year to Inland portions of Southern California, NWS meteorologist James Brotherton said. By Tuesday, highs are expected to reach 62 degrees in Van Nuys, 64 degrees in Rancho Cucamonga, 68 degrees in Whittier and 69 degrees in Anaheim.

Los Angeles County Public Health officials urged some residents to prepare for extreme cold Sunday evening, with low temperatures in mountain areas expected to stay within the 40s Monday and Tuesday. People in Santa Clarita and the Antelope Valley were advised to stay indoors, dress in layers and remember to take their pets inside overnight.

However, a return of Santa Ana winds typically brings warmer weather to Southern California beaches, Brotherton said.

Forecasts for the start of the week predict temperatures 3 to 8 degrees hotter than average along the coasts. Highs should reach 63 degrees in Malibu, 64 degrees in Newport Beach, 66 degrees in Long Beach and 70 degrees in San Juan Capistrano.

Moving forward, weather patterns are expected to shift again Wednesday, and a period of warm temperatures with low humidity is expected to persist from Thursday through Saturday. Then a cooling trend is forecast to form along with cloudier skies on the following Sunday and Monday.
