Rain to Give Way to Gusty Winds

Periods of light rain forecast Tuesday morning. Winds will increase through the day, peaking in strength in the evening and diminishing overnight.

High winds generated by a cold front out of the Gulf of Alaska will buffet the Southland Tuesday, mixing with snow and ice to make driving through such areas as The Grapevine "especially hazardous," forecasters said.

Light rain fell this morning, but the exiting storm's salient element will be the winds that will rise in its wake, with National Weather Service meteorologists forecasting gusts of 65 mph across the Interstate 5 corridor, up to 50 mph in the Antelope Valley and the Santa Monica Mountains Recreational Area, and 45 mph in the San Fernando and Santa Clarita valleys.

The most powerful gusts will occur this afternoon, tonight and overnight, according to NWS forecasters.

The snow level will drop to around 3,000 feet tonight, and snow showers are possible over The Grapevine.

"Snow, ice and gusty winds will make traveling through that area especially hazardous," according to an NWS advisory. "Winds are expected to peak Tuesday night before weakening on Wednesday."

Along with 65-mph gusts, sustained northwest winds of between 25 and 40 mph will sweep through the San Gabriels until early Wednesday, according to NWS forecasters.

A high wind warning denoting winds of at least 40 mph or gusting to 58 mph will be in effect from 4 p.m. today until 7 a.m. Wednesday in the San Gabriel Mountains in Los Angeles and Ventura counties. A less serious wind advisory, indicating that 35 mph or greater are expected, will be in force from noon today until midnight in the Antelope Valley, from 4 p.m. today until 7 a.m. Wednesday in the Santa Mountains Recreational Area and the Santa Clarita Valley, and from 6 tonight until 7 a.m. Wednesday in the San Fernando Valley.

The NWS forecast highs today of 40 on Mount Wilson; 49 in Palmdale; 50 in Lancaster; 53 in Avalon and Saugus; 57 in Burbank; 58 in Pasadena and San Gabriel; 59 in Anaheim and Woodland Hills; 60 in Long Beach and at LAX; 61 in downtown L.A.; and 62 in Newport Beach.

Wednesday's highs will be nearly identical, though under sunny skies. Clear weather is expected Wednesday through late Friday, when another relatively weak weather system will approach the region, according to the NWS.

But as of today, no rain was in the forecast until Sunday.
