Heat Advisory Issued for Southland


LOS ANGELES (CNS) - A heat advisory denoting an illness-inducing combination of high heat and high humidity will be in effect until tonight in L.A. and Orange counties.

The advisory will be in effect from 10 this morning until 8 tonight in both counties. During that time, temperatures of 85 to 95 degrees will prevail in coastal areas of L.A and Ventura counties and will rise to between 95 and 105 slightly inland in the valleys and mountains while Orange County experiences temperatures of 81 to 88, although the humidity will make it feel like it's 89 to 96, according to the National Weather Service.

“Dehydration, heat cramps and heat exhaustion are possible. If you have to be outside, drink plenty of fluids and stay out of the sun as much as possible,” advised the NWS station in San Diego, which monitors the weather in Orange County.

“Overexposure to the heat can cause heat cramps and heat exhaustion,” added the NWS station in Oxnard, which monitors the weather in L.A. County, among other areas. “Without intervention, that can lead to heat stroke.”

The heat advisory applied to all of L.A. County, except the Santa Monica mountains and Antelope Valley, while the one issued by the NWS in San Diego pertained to Orange County coastal areas.

“The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” urged the NWS in Oxnard.

Both NWS stations issued sharp warnings against ever leaving people or pets in vehicles parked in hot weather as internal temperatures, even with windows cracked open, can rapidly become lethal.

Because of high pressure over the Four Corners region, today's temperatures will run around 10 degrees above normal amid humidity levels of around 60 per cent, said Oxnard-based NWS meteorologist Todd Hall, adding that weekend conditions should be more pleasant because temperatures will drop and the high humidity will be dissipating.
