• List of cooling stations in LA County Triple-digit temperatures and high humidity continued to roil the area Thursday in a weather pattern that is expected to last through the Labor Day weekend, officials said. “It’s going to be hot and muggy through next Wednesday,” said Bill Hoffer, spokesman for the National Weather Service. “Pasadena should break the century mark and much of the San Gabriel Valley will be even warmer.” Humidity is expected to be in the range of 50percent to 80 percent, thanks to a weather system moving in from Mexico that is blanketing much of the state, Hoffer said. “One of the most important things is to never, ever leave anybody in a car – not a child, not an elderly person, not a pet,” said Jonathan Fielding, the director of Public Health for the Los Angeles County Department of Health Services. “In this kind of weather a car can become an oven in a matter of minutes.” While the Los Angeles County Department of Coroner reported no heat-related deaths through Thursday afternoon, Fielding said the health impact of high heat can be devastating in a variety of ways. “What we found last year is that we didn’t see a big spike in heat deaths, but an increase in death from heart disease,” Fielding said. “The heat puts an extra strain on people with chronic conditions. They are at higher risk unless they take the right precautions.” At the 7-Eleven on West San Bernardino Road in West Covina, water sales were brisk, according to a clerk there. “When it’s hot like this we always sell lots of water and sports drinks,” said Raj Singh, the clerk. “We’ve been busy today.” At the Altadena Senior Center on East Mariposa Street, seniors cooled off in 72-degree luxury, and talked about the overnight storm, according to receptionist Marge Marquez. “This is a great place for seniors to go and be cool. A lot of them don’t have air conditioning at home, so its far more comfortable here.” Marquez said she planned to stay indoors for the whole day, “just looking at the weather on the Internet. It looks like its pretty warm out there.” Thundershowers blanketed the region early Thursday bringing measurable rainfall to much of the area. While the storms subsided late in the day, the threat will exist in area mountains through the weekend, Hoffer said. McCorkle said the ISO took the rare step of holding a conference call with the state’s largest energy users and asked them to initiate voluntary reductions in power use. Those combined efforts appeared to work. The agency extended its statewide energy warning into today, marking a fourth consecutive day in which it projected high demand and urged conservation efforts. Southern California Edison recommended consumers set thermostats at 78 degrees or higher and use fans; not use major appliances such as washers and dryers during peak hours – 3 to 6 p.m.; draw the curtains to block out sunlight; use clothes and dish washers only for full loads; and close doors and vents to unoccupied rooms. Demand overloaded a distribution station in Sun Valley, triggering a rolling outage affecting about 2,000 Los Angeles Department of Water and Power customers. Throughout Los Angeles, a total of 3,500 residents lost power, spokeswoman Gale Harris said. Gov. Arnold Schwarzenegger directed California’s Office of Emergency Services and the state Department of Public Health to implement heat response plans as a result of heat advisories and extended periods of high temperatures. Part of the plan calls for the opening of state cooling centers. State cooling centers will be open in eight other counties and OES has established a toll-free number for the public to get information on how to protect themselves from the hot, humid weather: (877) 435-7021. The line will be active through Tuesday, officials said. The Associated Press and City News Service contributed to this story.

Early Thursday, the California Independent System Operator, the agency that manages most of the state’s electric grid, warned of potential trouble in the state’s power supply. It said it planned to declare a minor power emergency at 2p.m. and increase its alert level to a so-called Stage 2 emergency at about 4 p.m., the hottest point in the day when electricity use soars. Neither alert was necessary, as the state’s largest electricity consumers voluntarily cut their use. The state’s power consumption peaked at 47,843 megawatts, well below the predicted peak of 49,105 megawatts. “Residents really responded and we want to thank them,” said Stephanie McCorkle, spokeswoman for California’s Independent System Operator. “The conservation we saw today from Californians saved the equivalent of a large power plant.” Highs hit 102 degrees in Pasadena, El Monte and West Covina, 94 in Whittier, 96 in Pico Rivera, 103 in Monrovia, 104 in Glendora and Diamond Bar and 105 in Pomona. Officials Thursday urged residents to take precautions for themselves and others.
