SACRAMENTO (CBS13/AP) — Northern California is going to roast this holiday weekend, with temperatures expected in the triple digits.
The National Weather Service has issued an Excessive Heat Watch for Saturday through Tuesday, Sept. 8. For the valley and foothills, temperatures are forecasted to reach up to 110 degrees. In the mountains, highs may reach around 100 degrees.READ MORE: Proposed Casino Near Elk Grove Secures Funding
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.
Officials recommend drinking extra water, avoiding strenuous outdoor activities between 10 a.m. and 6 p.m., and planning to be in air-conditioned buildings.'We Have Upheld Every Commitment': Steinberg Says Sacramento MLS Expansion Efforts To Continue After Lead Investor Backs Out
Earlier this week, CBS13 asked the California Independent System Operator – the managers of the state power grid – if they’re concerned by this coming weekend’s high heat, and they said they’re not anticipating outages because this heatwave is expected to be milder than the one in early August.
But things could change quickly if a power plant trips offline or if transmission lines are impacted by fires.
The manager of the state power grid issued a Flex Alert calling for voluntary electricity conservation Saturday through Monday between the hours of 3 p.m. and 9 p.m.
The California Independent System Operator earlier ordered power generators to postpone outages for routine maintenance from 6 a.m. Saturday to 8 p.m. Sunday.
The early August outages came in the middle of a perfect storm that forced the first stage three emergency for a strained power grid in nearly 20 years.MORE NEWS: Grant High Teacher Under Fire For Reportedly Making Racist Gesture During Online Class
Record-breaking heat caused a surge in demand for power all across the state. California was unable to import energy from states like Arizona and Nevada, both of which typically can supply extra power to the Golden State, if needed, but they were struggling with a heatwave of their own.
