The worst heat wave of the year will ravage Southern California at least through Wednesday.
Here’s an overview of what to expect:
Saturday and Sunday will see “high” and “very high” heat readings in many areas, said Tom Fisher, meteorologist with the National Weather Service in Oxnard.
But Sunday will likely bring the most intense temperatures of the heatwave.
Heat warnings have been issued for inland and valley areas where temperatures will hit triple digits with some places exceeding 110 degrees, but also for some coastal towns where temperatures will reach into the 90s.
“An extended period of very hot conditions with minimal coastal cloud is expected as high pressure remains anchored in the air over the west,” the National Weather Service said. “By early next week there will be triple digit heat for many valley and mountain resorts. Record-breaking heat leads to a very high risk of heat-related diseases.”
Muggy temperatures will continue into next week, with some cooling expected by mid-week.
Some inland areas have set daily temperature records for the past three days.
Challenges in the energy grid
The California Independent Systems Operator, which manages the power grid, has extended a flex alert through Saturday, officials announced Friday night.
During a flex alert, consumers are encouraged to save energy from 4 p.m. to 9 p.m., hours when the grid is at its busiest. Officials warn of potential power outages during the heatwave due to excessive demand.
Here’s a guide on how to save power during Flex Alerts.
