Excessive Heat Warning Effective Sunday for San Diego County

San Diego County, CA — With an excessive heat watch expected to be in effect Sunday through Wednesday for much of Southern California, heat-related illnesses are possible for those who do not take precautions.

The National Weather Service announced an upper-level high pressure building over the area that will create high temperatures in excess of 10 to 20 degrees above normal. Temperatures between 95 and 105 degrees are forecast for the valleys of San Diego County, while the desert areas within the county will see high temperatures between 110 and 120 degrees.

The impact of this extreme weather includes heat-related illness, which is likely for those involved in strenuous outdoor activity, or those with health conditions that do not have adequate access to air conditioning. If left untreated, some illness events could be fatal.

PRECAUTIONARY/PREPAREDNESS ACTIONS:

Look for a cool center in your area:

• A list of San Diego County Cool Zones is available for those who are unable to seek shelter from the high temperatures.

Look before you lock:

• Never leave children, elderly adults or pets inside a vehicle, even when running a quick errand.
• Studies show that when temperatures are in excess of 95-degrees, within 10 minutes, your car temperature will be over 114-degrees.
• If you see a child, elderly adult or pet left alone in a car in the heat, officials advise to call 9-1-1
