A Dangerous Heat Wave About To Roil The Southland


LOS ANGELES (CNS) - Another heat wave will grip the Southland throughout the upcoming holiday weekend, creating heightened risk of heat-related illnesses and threatening wildfires and power outages.

“Dangerous heat'' is expected from Friday through Labor Day, the National Weather Service warned on its website.

Woodland Hills is forecast to hit highs 115 degrees Sunday, when Antelope Valley cities will reach 111 and Saugus 112, according to the NWS.

The anticipated high temperatures are also sparking concerns about demand on the state's power grid as residents turn up their air conditions units.

The California Independent System Operator, which manages the power grid, announced that a Flex Alert -- a call for voluntary conservation – will be in effect from 3 to 9 p.m. Saturday through Monday. Urging voluntary conservation is an effort to stave off to much strain on the state's electrical system, possibly leading to rolling power outages, like those that occurred during high heat last month.

An excessive heat warning issued by the NWS will be in effect from 10 a.m. Friday until 8 p.m. Monday in the San Gabriel and Santa Monica mountains, Santa Catalina Island and the San Fernando, Santa Clarita, San Gabriel and Antelope valleys. In Orange County, the warning will be in force in coastal areas from 10 a.m, Saturday until 8 p.m. Monday.

“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.'' according to an NWS statement.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,'' the NWS advised, adding that children, seniors and pets must never be left unattended in vehicles under any circumstances in since temperatures can quickly turn lethal in the current conditions.

“Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible.''

The weather service noted that the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments.

The high heat is being attributed to high pressure, which was centered near the California-Nevada border Wednesday evening and is forecast to settle into the Great Basin area through the weekend.

In forecasting an increased fire danger, forecasters said they were mainly focusing on the dryness that will take hold in the region, partly because of the absence of monsoonal moisture. NWS meteorologist David Sweet said humidity levels will fall to single digits in interior areas of L.A. County today. But no red flag warnings indicating a high risk of wildfires are likely to be issued because there's very little wind, if any.
