A Heat Wave going to hit SoCal this Week with Muggy Weather

SOUTHERN CALIFORNIA, CA. (Pain In The Pass) >> Inland Empire and the deserts will face dangerous heat and muggy weather for the next six days or more.

Also, this brings an elevated fire danger across Southern California with a high risk of fast-moving wildfire without the strong gusty winds. Sundowner winds are not out of the question each day.

During the peak of this Weather Alert, we’ll also see very warm overnight lows.

The heat wave blasting into Southern California is being caused by a huge ridge of high pressure currently centered over Utah.

This heat wave can expect temps to hit over 100° to 110+° on Wednesday through next week.

Heat Health Safety Tips:

Stay hydrated! The more hydrated you are, the more effective your body will be keeping your cool. Drink water – not soda, energy drinks, and alcoholic drinks, which will dehydrate you.

Avoid exercise in the middle of the day. If you need to exercise outside, do it early in the morning when the temperature is lower.

Wear lightweight, light-colored natural fabrics like cotton and linen, as these will help your skin breathe and let your sweat evaporate, this will keep you cooler.

Turn off big appliances and help prevent black-outs!

Make sure your pets have shade and lots of water.
