Powerful winds lashed portions of the Southland Monday, while sailors confronted rough seas and high surf and strong rip currents created perilous conditions for swimmers and surfers.

The Antelope Valley was receiving the brunt of the wind, and a wind advisory will be in force for the area until 8 p.m. A high wind warning denotes an expectation of 58-mph winds or gusts.

Northwest winds of between 25 and 40 mph are expected through the afternoon, with gusts up to 65 mph possible, according to the National Weather Service.

“Winds this strong may down trees and power lines and cause property damage,” according to an NWS statement.

Additionally, “strong winds can make driving difficult, especially for drivers of high-profile vehicles and vehicles towing trailers. Blowing sand and dust will cause visibility to lower to near zero at times.”

Somewhat tamer but sill potentially destructive winds are expected outside the Antelope Valley.

A wind advisory will be in effect until 10 a.m. Tuesday in the San Gabriel mountains in both Los Angeles and Ventura counties. Northwest winds of 20 to 30 mph will sweep mountain areas, accompanied by 50-mph gusts, according to the NWS.

Winds of 20-30 mph are expected, along with 40 mph gusts, on Santa Catalina Island, in beach cities, metropolitan Los Angeles, downtown L.A. and the Hollywood Hills, according to forecasters, and a wind advisory will be in effect in those areas until 9 Monday night.

In the Santa Clarita and San Fernando valleys, northwest winds of between 15 and 25 mph are expected, along with 40 mph gusts. A wind advisory will be in force from noon Monday until 3 a.m. Tuesday in the Santa Clarita Valley and from 3.p.m. Monday until 3 a.m. Tuesday in the San Fernando Valley.

In Orange County, where winds of between 15 and 25 mph are expected, along with gusts of between 35 and 40 mph, a wind advisory will be in effect from noon until 9 p.m.

Off the coast, mariners will confront rough seas, according to the NWS. A gale warning will be in force off Santa Catalina until 9 tonight, and until 5 a.m. Tuesday in other sectors.

The ocean off Catalina is expected to experience west winds of between 20 and 30 knots, along with 40-knot gusts, forecasters said, adding that combined seas of 11 to 14 feet are possible.

“Operating a vessel in gale conditions requires experience and properly equipped vessel,” according to the NWS. “It is highly recommended that mariners without the proper experience seek safe harbor prior to the onset of gale conditions.”

Also in effect Monday was a high surf advisory, which will be in force until 5 a.m. Tuesday in Los Angeles, Ventura and Santa Barbara counties. Forecasters warned of surf of between four and seven feet, with sets of nine feet along the Palos Verdes Peninsula.

“Large waves and strong rip currents will make swimming and rock jetties dangerous,” an NWS statement said. “If caught in a rip current, swim parallel to shore until you are free… Always swim near a lifeguard.”

Temperatures, meanwhile, will be higher Tuesday — around five degrees in some communities — but revert to Monday’s levels on Wednesday and Thursday, “as a weak weather system moves through the region with a slight chance of showers,” according to the NWS. But warmer weather is predicted for next weekend.
