The National Weather Service has issued an extreme heat warning for Wednesday, July 22, 2026, valid from 11:00 a.m. to 8:00 p.m.

WHAT TO DO DURING AN EXTREME HEAT WAVE:
The Houston Department of Health recommends taking the following precautions to prevent heat-related illnesses, such as heat exhaustion or heat stroke.

• Never leave babies, children, elderly people, or pets unattended in a parked vehicle, even if the windows are slightly open.
• Make sure everyone has exited the vehicle and do not overlook children who may have fallen asleep.
• Carry a bottle of water and increase your water intake. Drink plenty of fluids even before you feel thirsty, but avoid caffeinated, alcoholic, or high-sugar drinks, as they can lead to bodily fluid loss.
• Perform outdoor work or exercise in the early morning or at sunset, when temperatures are not as high.
• Outdoor workers should drink plenty of water or electrolyte-rehydration drinks and take frequent breaks in the shade or in air-conditioned facilities.
• Wear light-colored, loose-fitting clothing that allows sweat to evaporate.
• Wear a wide-brimmed hat to help prevent sunburn and heat-related illnesses.
• Apply sunscreen to protect yourself from the sun’s harmful rays and reduce the risk of sunburn.
• Take breaks in cooling centers or any air-conditioned facility.
• Take cool baths or showers frequently if your home does not have air conditioning.
• Keep your pets indoors. Asphalt and dark pavement can get very hot and burn your pet’s paws. Make sure they have plenty of fresh water.
