HOUSTON — Dangerous heat is tightening its grip on Southeast Texas, and forecasters are not holding back: this week’s conditions could turn deadly.
The National Weather Service has issued an Extreme Heat Warning for the Houston area, with heat index values expected to climb between 110 and 115 degrees on Wednesday — high enough to cause rapid heat stroke in vulnerable individuals, even with limited outdoor exposure.
Tuesday is already brutal, with temperatures reaching 99 degrees and a heat index between 104 and 108 degrees. A Heat Advisory remains in effect from 11 a.m. to 8 p.m. Wednesday is expected to be significantly worse, with some inland areas pushing past 100 degrees.
Why Nighttime Offers No Relief
What makes this heat wave especially dangerous is what happens after sunset — nothing.
Overnight lows are expected to stay between 75 and 80 degrees across the region. When temperatures fail to drop at night, the human body cannot recover from daytime heat stress. This dramatically increases the risk of heat exhaustion and heat stroke, especially for outdoor workers, elderly residents, children, and anyone without reliable air conditioning.
Tropical Storm Bertha Adds to the Outlook
As the heat dominates, forecasters are also watching Tropical Storm Bertha, currently moving through the Gulf with 60 mph sustained winds. The storm is expected to weaken before reaching Texas, but its remnants could bring rain to Southeast Texas late in the week — providing some relief, though the exact timing remains uncertain.
