A heat advisory is in effect for southern Texas, with the National Weather Service forecasting heat index values from 111 to 116 degrees Fahrenheit. These extreme "feels like" temperatures are driven by high heat and humidity, surpassing normal early May averages by 20-25 degrees.
The advisory impacts inland Kenedy, southern Hidalgo, inland Willacy, and inland Cameron counties. Cities including McAllen, Edinburg, and Brownsville are affected. Residents are advised to stay indoors in air-conditioned environments and maintain hydration.
Extreme heat poses a significant health risk, increasing the danger of heat exhaustion, dehydration, and heat stroke. The NWS recommends taking precautions before the hottest parts of the day and seeking immediate medical attention for signs of heat stroke.
