LOS ANGELES (CNS) – Strong and potentially damaging winds will lash away at mountain and valley areas of Los Angeles County as well as San Bernardino County today and Tuesday morning, according to the National Weather Service.
Following a dry cold front, the winds will pick up this afternoon and blow in a west-to-northwest direction, then strengthen as they turn northerly tonight and Tuesday morning, said an NWS statement.
A wind advisory will be in effect from noon today to 6 a.m. Tuesday in the Los Angeles County portion of the San Gabriel Mountains, where winds of between 20 and 30 miles per hour gusting to 45 mph will blow this afternoon before increasing tonight to between 25 and 40 mph with 60-mph gusts, warned an NWS statement.
The wind advisory will be replaced tonight with a more serious high wind warning, said the NWS, adding that the strongest winds lashing the mountains will be in the Interstate 5 Corridor.
A wind advisory is issued in anticipation of winds or gusts of 35 mph. A high wind warning signifies an expectation of 58-mph winds or gusts.
“Winds this strong may down trees and power lines, causing property damage or power outages,” said the NWS statement. “Cross winds can make driving difficult, especially for drivers of high-profile vehicles and vehicles towing trailers.”
Such strong winds could seriously impede visibility by churning up dust and sand, warned the statement, which also urged residents to “be prepared to secure all loose outdoor furniture in advance of the onset of strong winds.”
A wind advisory will also go into effect at noon in the Santa Clarita Valley, where it will expire at 6 p.m. and be replaced with a high wind warning lasting until Tuesday morning. In the Antelope Valley, the wind advisory will end at 9 p.m., and no high wind advisory was immediately anticipated.
In the Inland Empire, a wind advisory will be in effect from 10 p.m. today through 2 a.m. Tuesday, with areas affected including local foothills as well as the cities of San Bernardino, Fontana and Corona.
NWS forecasters said winds of 15-25 mph gusting to 35 mph are expected in the Santa Clarita Valley this afternoon, strengthening to between 25 and 35 mph with 60-mph gusts tonight into Tuesday morning. In the Antelope Valley, the wind is expected to blow at between 25 and 35 mph this afternoon, gusting to 50 mph.
Along the coast, a small craft advisory will be in effect until 11 this morning, and a gale watch will be in force from this morning through Tuesday morning. The NWS forecast northwest winds of between 20 and 30 knots and seas of up to 10 to 13 feet.
