NWS: Excessive Heat Warning Issued – Sunday Will Be Hotter Than Saturday

SAN ANGELO – National Weather Service meteorologists have added an Excessive Heat Warning to the Heat Advisory for Sunday afternoon as the oppressive heat rises even higher.  

The forecast calls for afternoon high temperatures to reach near 110 degrees in some areas of West Texas making spending time outdoors in the sun dangerous and even deadly. 

The Excessive Heat Warning is in effect from 1 p.m. to 7 p.m. while the existing Heat Advisory remains in effect until 7 p.m.

An Excessive Heat Warning means heat index values will reach hover around 105 degrees with afternoon high temperatures as high as 108 common across the region.  Heat illnesses will occur as the string of 100 degree heat days drags on. 

Residents are encouraged to stay inside an air-conditioned building Sunday afternoon.  If you do go outside, limit activities to the early morning or late evening hours.  Drink plenty of non-alcoholic fluids, wear lightweight loose fitting clothing, take plenty of breaks in the shade, and know the signs of heat related illnesses.  Check up on vulnerable family members and neighbors.  And make sure all outdoor pets have plenty of fresh water and shade. 

Never, ever leave a pet or a child in a locked vehicle.  Temperatures can turn deadly in a matter of minutes in conditions like these.  

The high temperature in San Angelo Saturday officially was 107 degrees with the average temp at 91 degrees.  Expect a sustained high temperature of 108 and above Sunday afternoon.  

The string of 100 degree days continues for at least the next ten days.  Some forecast models show a high of only 99 degrees on Wednesday but that could chance.  

Evaporation of water supplies for people, crops, livestock and wildlife will begin to be a concern.  While there is an adequate supply of water for the City of San Angelo for at least 30 months, tanks, creeks and springs will begin to dry up and rivers and reservoirs will be next as the heat continues.  Now is the time to begin conserving water.  

Sunday's extreme heat has the potential to be deadly.  Residents are urged to monitor local weather sources throughout the day for further updates.
