TRABUCO CANYON, CA — A low pressure system developing over Arizona Monday on Tuesday caused a high pressure system to drive gusting winds into Orange County, the National Weather Service said. Those winds are slated to keep gusting through Tuesday afternoon.
Areas affected by the highest gusts include Irvine and Mission Viejo, according to the NWS, who issued a wind advisory from 6 a.m. through 1 p.m. Tuesday.
"Winds are expected to blow with gusts from 55 to 60 miles per hour at times in the mountains, and 20 to 30 miles per hour in the coastal plain area, with local gusts from 45 to 50 miles per hour," they said.
Watch out for minor tree damage and possible travel delays, due to cross winds and debris blowing across the roads, they added.
Winds make travel difficult, especially for high profile vehicles.
"Watch out for falling palm fronds, and use extra caution while driving," the NWS said.
A warming trend got underway Tuesday in the Southland, where temperatures are expected to rise by several degrees.
The higher temperatures are the result of warm gusty winds, which will sweep the region through Tuesday morning, and a ridge of high pressure from the Pacific, which will shift to the east later this week, said National Weather Service meteorologist Kathy Hoxsie.
Wind advisories will be in effect until noon in the L.A. coastal zone, which consists of County beach cities, metropolitan Los Angeles, and the Hollywood Hills; the San Fernando, Santa Clarita and San Gabriel valleys; the San Gabriel and Santa Monica mountains; and until 1 p.m. in coastal and inland Orange County. Winds of 15-25 mph were expected, along with 35-mph gusts.
The NWS forecast sunny skies Tuesday in Orange County Tuesday, along with highs of 70 in Newport Beach, 74 in Laguna Beach and San Clemente; 76 in Yorba Linda; 77 in Anaheim, Irvine and Mission Viejo; and 79 in Fullerton.
Orange County temperatures are up to six degrees higher than Monday and will begin declining along the coast Wednesday while dropping or rising minimally in inland areas. A drop of 3-5 degrees is expected Saturday.
Sunny skies were also forecast in Los Angeles County and San Gabriel Valley, with highs of 59 degrees on Mount Wilson; 67 in Avalon; 68 in Palmdale and Lancaster; 71 in Saugus; 72 at LAX; 74 in Burbank; and 76 in Downtown L.A., Long Beach, Pasadena, San Gabriel and Woodland Hills.
By Thursday, Downtown will have a high of 78, Burbank 80 and Woodland Hills 82. A cooling trend will begin in L.A. County on Friday with a decline of a few degrees. By Sunday, L.A. County highs will range mostly from the mid 60s to the low 70s.
