LOS ANGELES (AP) — California is forecast to heat up through the Labor Day weekend under the influence of a massive area of high pressure that is expected to produce dangerously high heat.
The heat is expected to set in Friday in the south and spread northward, peaking on Sunday or Monday, according to the National Weather Service.
Many temperature records are likely to fall and there is a chance that some all-time record highs will be recorded, the weather office for the Los Angeles region said Thursday.
“These extreme max temps, combined with lows in the mid-70s to lower 80s will make Sunday one of the most hazardous in recent memory,” the office said.
The manager of the state power grid issued an order for power generators to postpone outages for routine maintenance from 6 a.m. Saturday to 8 p.m. Sunday, but said earlier this week it was not planning any Flex Alerts, which call for voluntary conservation, or so-called stage emergencies that can lead to rolling blackouts.
A mid-August heat wave strained the grid to the point where the California Independent System Operator ordered utilities to implement brief rolling blackouts for the first time since 2001.
Cal ISO said it would issue an update closer to the weekend.
