The National Weather Service issued an extreme heat watch for Orange County on Friday, covering the period from Monday morning through Friday, March 20 at 8 p.m.
Forecasters are warning of "dangerously hot conditions" with highs of 85 to 90 degrees near the coast and up to 105 degrees inland. Temperatures next week are expected to run 20 to 30 degrees above normal for this time of year, and the NWS says record-breaking heat is likely at some locations.
The early timing makes this event particularly concerning. Heat illness becomes more dangerous when people haven't yet adjusted to warmer temperatures, and many residents won't have air conditioning running or cooling plans in place this early in March.
"Early time of year and prolonged nature of this heat event will lead to increased risk of heat illness, especially for vulnerable populations and those without cooling systems," the NWS said.

How to Stay Safe
- Drink water constantly. The UC Irvine Environmental Health office recommends 3 to 4 cups of water every hour during exposure to extreme heat. Avoid alcohol and caffeine, which dehydrate the body.
- Take breaks in the shade. Don't push through the heat. Shaded rest helps the body recover.
- Watch for warning signs. Nausea, dizziness, weakness, or unusual fatigue are signals to stop and get somewhere cool. If symptoms don't improve quickly, seek medical attention.
- Check on neighbors. Elderly residents and those without air conditioning are at greatest risk. A knock on the door can save a life.
The weekend is expected to be slightly cooler before temperatures surge Monday. Plan outdoor activities accordingly.
