Red flag warnings denoting a high risk of wildfire and excessive heat warnings outlining significant health risks were in effect in the Southland and scheduled to expire Wednesday evening, but wind advisories were rescinded hours before they were due to run out.
The red flag warnings were scheduled to be in effect everywhere in Los Angeles County, except for the Antelope Valley, and parts of Ventura County until 6 p.m.
The wind advisories were to expire at 2 p.m. but were called off shortly after 9 a.m., with the National Weather Service reporting that the winds had weakened, although gusts of up to 45 miles per hour remain possible in the mountains.
The excessive heat warnings, which were due to expire at 8 p.m. Tuesday, are now scheduled to remain in force until 8 Wednesday evening.
“The very high temperatures create a dangerous situation in which heat illnesses are possible,” warned a National Weather Service statement. Temperatures inside vehicles, even if the windows are partially open, can quickly rise to life-threatening levels.
The NWS forecast sunny skies Wednesday and highs of 85 on Mount Wilson; 87 in Palmdale; 88 in Lancaster; 90 in Avalon; 95 at LAX; 98 in Long Beach; 100 in Downtown L.A., San Gabriel, Burbank and Woodland Hills; and 101 in Pasadena.
