Metro Health Issues Excessive Heat Warning Level I

CONTACT: Carol Schliesinger, 210-207-8172


SAN ANTONIO (July 23, 2018) –  The San Antonio Metropolitan Health District (Metro Health) is notifying the community of a level I “excessive heat warning.” Level I indicates a sustained heat index greater than or equal to 113 degrees Fahrenheit or air temperature greater than or equal to 105 degrees Fahrenheit.


With increasing heat, Metro Health reminds the community to take the following precautions: 


  • Spend time in public/private locations with air-conditioning such as public libraries, recreation centers, senior centers, shopping centers/malls, during their business hours. Air-conditioning is the number one protective factor against heat-related illness and death.
  • Stay well hydrated, regardless of your activity level.
  • Wear lightweight, light-colored, loose-fitting clothing and appropriate sunscreen.
  • Avoid alcohol and caffeine intake.
  • Avoid heavy and/or hot foods—they add heat to your body.
  • Limit outdoor activities during the heat of the day. Exposure to full sunshine can increase Heat Index Values by up to 15°F.
  • Monitor those at high risk such as the elderly, infants, young children, and people who are ill or have chronic disease, such as heart disease or high blood pressure.
  • Never leave children or pets unattended in a closed, parked vehicle.


Information on cooling centers location is available online at the Office of Emergency Management website.


Sunstroke, heat cramps or heat exhaustion is highly likely with continued exposure to this heat level.


Warning signs of heatstroke include: red, hot, and moist or dry skin, no sweating, a strong rapid pulse or a slow weak pulse, nausea, confusion or acting strangely. If a child exhibits any of these signs after being in a hot vehicle, cool the child rapidly (not an ice bath but by spraying them with cool water or with a garden hose). Call 911 or your local emergency number immediately.


Metro Health’s heat plan follows the national weather service levels. The format resembles a countdown, with Level IV stating a normal/routine condition and Level I representing a maximum readiness/excessive heat warning. The heat plan provides information on how individuals can prepare for, prevent, recognize, and cope with heat-related health problems. Additionally, the plan provides a list of local agencies which will furnish cooling assistance during extreme heat weather conditions. We encourage individuals to share this plan with anyone who might utilize this information. Click here to access the heat plan.


Community members can contact the National Weather Service for the most current weather conditions at 830-606-3617 or visit for current hourly weather. Stay tuned for further notices.
