Blistering temperatures continue to plague the southern U.S. from New Mexico to Florida for yet another week which has caused records to fall.
Austin, Texas, the capital of the Lone Star State, has seen highs in the triple digits for 35 consecutive days. That streak beats the previous record of 27 consecutive triple-digit days in 2011, and it shows no signs of stopping.
Across the South, Heat Advisories and Excessive Heat Warnings remain in place from Texas east across the Gulf Coast states, including the Florida Peninsula, where above-average to record-breaking heat will continue through Sunday.
The combination of heat and humidity will result in dangerous heat indices, possibly climbing above 110 degrees in some locations, according to the FOX Forecast Center.
Midland, Houston and Dallas are forecast to have temperatures above 100 on Sunday. New Orleans, Louisiana, and Memphis, Tennessee, are both forecast to reach the high 90s, and Jackson, Mississippi, will be in the triple-digits.
"It has been a hot summer down South, and you might be saying, 'It's always hot in the South,' but this has been a tremendous stretch, very persistent," FOX Weather meteorologist Britta Merwin said, adding the heat is now a health and safety hazard.
Come Sunday, millions of Americans will be dealing with triple-digit heat.
No relief in sight
The heat wave has turned deadly for dozens of people. The most recent fatality happened Tuesday in Houston, where a 3-month-old boy died after being left inside a vehicle.
"Make sure you are setting that reminder, so you look and pay attention to what's going on," Merwin said. "Never leave the car before checking the back seat."
