Red flag warnings and high wind advisories remained in effect Tuesday across much of Southern California, as weather conditions prompted fire agencies to increase staffing in high-risk areas.
In the coastal, valley and mountain areas of Los Angeles and Ventura counties, a red flag warning was extended through 8 p.m. Wednesday due to gusty winds and low relative humidity, according to the National Weather Service.
Portions of the two counties were experiencing Santa Anas that prompted the Weather Service to issue a high-wind advisory until 3 p.m. Tuesday. Gusts of up to 40 mph were expected for the coast and most valleys, with 45- to 50-mph winds in the Santa Clarita Valley and the Santa Monica Mountains.
Drivers – especially those of vehicles towing trailers — were urged to use extra caution and be prepared for sudden crosswinds, particularly on Interstate 5 and Highway 14.
A red flag warning was also issued until 8 p.m. Wednesday for Orange County, the Inland Empire, and the mountain areas of San Bernardino and Riverside counties, the Weather Service said.
A wind advisory was in effect until 4 p.m. Wednesday along the Orange County Coast, with a heat advisory until 6 p.m. Thursday in the same area.
The hazardous fire conditions resulted in closure of multiple roads in L.A. County.
In Glendora, the U.S. Forest Service shut down Glendora Mountain Road between Big Dulton Canyon Road and Glendora Ridge Road through at least Wednesday. Glendora Ridge was closed between Mount Baldy Road and Glendora Mountain Road through Tuesday, the Forest Service said.
Meanwhile, the Angeles National Forest was staffed 24 hours a day with 23 fire engines, six patrols, 5 water tanks, the agency said on Twitter.
With temperatures expected to reach triple digits in come areas, the L.A. County Dire Department tweeted out a list of local cooling centers.
County officials urged residents to take precautions to protect themselves from the sun and heat, including:
- Avoid the sun between 10 a.m. and 3 p.m., when the burning rays are strongest,
- Set air conditioners between 75 degrees and 80 degrees, or take a cool shower twice a day,
- Check on elderly neighbors, family and friends who do not have air conditioning,
- Drink plenty of fluids and avoid alcohol,
- Reduce physical activity, and
- Use a sunscreen with a sun protection factor of at least 15 if exposure to the sun is necessary.
