Records could be broken this week as the Central Valley and much of California experience record high temperatures in September.

On Tuesday, meteorologists expected Visalia to hit 113 degrees. The chance of Fresno hitting 112 degrees or higher was about 50 percent, which would set a record for September since records began in 1887, according to the National Weather Service.

In response to an excessive heat advisory issued by NWS, the Visalia Transit Center will remain open as a cooling center until Friday.

The Cool Center is open from 10 a.m. to 10 p.m. and is located at 425 E. Oak Ave. There are seats, vending machines and restrooms in the building. In addition, most bus lines lead to the transit center.

The Central Valley isn’t the only region experiencing record heat in California.

The state faces its greatest risk of outages this year amid the brutal heat wave. California energy officials said electric load Tuesday afternoon could top 51,000 megawatts, the highest demand the state has ever seen.

As people turn on their air conditioners, the state is forecasting record levels of power consumption, said Elliot Mainzer, president of California Independent System Operators, which operates the state’s power grid. The state currently has additional energy capacity “but blackouts, rolling blackouts and rotating blackouts are a possibility,” Mainzer said, calling the additional conservation “absolutely essential.”

The CAISO site on Tuesday morning showed that California could miss more than 5,000 megawatts of its peak on-demand power supply, scheduled for 5:30 p.m.

The state agency issued a Flex Alert appeal for voluntary conservation between 4 p.m. and 10 p.m. Tuesday, making seven alerts in as many days. Consumers were urged to keep air conditioners at 78 degrees or higher during the period and to avoid using major appliances such as ovens and dishwashers.

Efforts have worked to keep the lights on ‘but we’ve now entered the most intense phase of this heat wave’ which could last all week, and two to three times the level of conservation will be needed from individuals and businesses, Mainzer said. .

The state may see some extreme heat relief on Friday, but an excessive heat warning will be in place until then.

By the weekend, there is a chance that more tropical humidity will arrive and bring scattered showers and thunderstorms, due to Hurricane Kay which is currently off the coast of southern Baja.

“Given the possibility of this tropical system passing relatively close to Southern California, showers and thunderstorms could occur almost anywhere in our forecast area, although confidence in this scenario remains low.” , NWS said in the Tuesday daily forecast discussion.

While meteorologists aren’t sure if the Central Valley will see any rain, they’re “more certain” the region will get a triple-digit heat break.
