Southern California residents can expect sunny skies, warm temperatures and a high-wind advisory in place until late Sunday afternoon, according to forecasters.

The high-wind warning will be in effect from 10 p.m. Saturday until about 4 p.m. Sunday for mountain areas in Los Angeles and Ventura counties. Northeast winds of 25 to 40 mph are expected with Santa Ana gusts of up to about 60 mph, said David Sweet, a weather service meteorologist in Oxnard.

The strong winds could blow down power lines, small trees and weakened branches.

During this same period, a wind advisory for northeast winds of 15 to 30 mph with gusts to between 35 and 50 mph will be in effect for the valleys and coastal areas of Los Angeles and Ventura counties, Sweet said.

The strongest Santa Anas will be found in the higher elevations of Ventura and Los Angeles counties, as well as in the Santa Monica Mountains, according to AccuWeather.com.

Similarly, on-shore winds will blow dust around along the Orange County coast and in mountains and foothills. Temperatures there will hover around 70 degrees, with the Inland Empire experiencing the mid-60s, said James Thomas, a meteorologist with the National Weather Service in San Diego.

Across San Diego County and portions of the Inland Empire, strong northeast winds are expected to persist until Monday morning, with gusts exceeding 55 mph affecting travel on Interstate 15 and California 91. Interstate 10 will also be affected through the San Gorgonio Pass.

Anthony Sagliani, an AccuWeather.com meteorologist, said the Santa Anas should subside by Tuesday morning across most areas. Temperatures are expected to warm significantly throughout the week, with some spots reaching highs near the 80-degree mark by Friday.
