Extreme heat watch to take effect Monday across most of SoCal: Here’s what to know

LOS ANGELES () — The National Weather Service has issued an extreme heat watch that is scheduled to go into effect Monday across most of Southern California, kicking off a week of soaring temperatures.

With five-day temperatures expected to top out at 102 degrees in Covina, 100 degrees in Santa Clarita and Canoga Park, and 98 degrees in Lancaster, the weather service described the conditions as “extremely rare” for March, adding that there will be a high risk for heat illness.

As high temperatures reach 25-35 degrees above normal, many daily records will be shattered and some monthly records will likely be broken, the agency said.

Peak heat timing

Forecasters predict the heat will reach its apex on Tuesday and Wednesday in the coastal areas, Tuesday through Friday in the valleys, and Wednesday through Friday in the mountains and deserts.

Suggested actions

In a statement issued Friday, the weather service recommended adjusting plans for strenuous outdoor activities to the early morning hours.

“If you do not have air conditioning, plan now on how you will stay cool,” the statement said. “Check in on the elderly — make sure they’re aware and prepared for the heat.”

If temperatures reach the expected heights next week, it would mark the hottest March period since 1988, officials said.
