Southern California Faces another Heatwave this Time will be Long and could be Dangerous

SOUTHERN CALIFORNIA, CA. (Pain In The Pass) >> A heatwave that’s expected to rank among the hottest of the year so far, will peak on Saturday and will last over a week long.

A slight cooldown is expected on Tuesday and Wednesday, with temperatures dropping by a degree or two.

Bad news, the Big-O high-pressure system will begin shifting back toward Arizona on Thursday, bringing afternoon highs over 100° to 105+° to parts of the Inland Empire Valley. Over 110° to 120+° for the high and low deserts cities.

This will cause the overnight temps to be in the 80’s or higher. This will be no relief at night.

You can guarantee this they will issue an Extreme Heat Warnings and Advisories for parts of SoCal.

Heat Health Safety Tips:

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

Do Not leave pets or children in unattended vehicle. Look Before You Lock!

This heatwave can expect temps to hit over 105° to 120+° start on Thursday through next week and end around Friday August 8.
