McALLEN, Texas – Dangerous heat will remain the Rio Grande Valley’s main weather concern this week, with afternoon heat index values expected to reach roughly 105 to 110 degrees in many communities.
Forecasters said high temperatures will climb into the upper 90s and lower 100s across inland areas. Humidity will make conditions feel hotter, particularly during the afternoon and early evening.
Residents should limit strenuous outdoor activity during the hottest part of the day, drink water frequently and check on older adults, children and people without reliable air conditioning. Anyone working outside should take regular breaks in shade or air conditioning.
Cars can become deadly within minutes in summer heat. Children and pets should never be left in a parked vehicle, even briefly.
A small chance of showers and thunderstorms is expected to return Friday as additional Gulf moisture reaches South Texas. Any rain could provide temporary relief, but widespread cooling is not expected.
Signs of heat exhaustion include heavy sweating, dizziness, weakness and nausea. Confusion, loss of consciousness or a body temperature near 103 degrees can signal heat stroke and require immediate emergency care.
