Heat dome brings life-threatening temperatures to millions across Southeast, Florida
July will make a potentially record-breaking exit this week as a heat dome will create triple-digit feels-like temperatures for millions from Florida to Virginia, prompting heat alerts across the East Coast.
A massive “dome” of high pressure known as a heat dome has shifted to the Southeast, bringing potentially record-breaking temperatures this week.
On Sunday, Tampa, Florida, soared to 100 degrees by 3:30 p.m., breaking the Florida city’s all-time record-high temperature since recordkeeping began in 1890.
Tampa, Florida, reached 100 degrees on Sunday, July 27, 2025, setting a new record high.
Extreme Heat Warnings have been posted for portions of the Southeast coast for Monday, including parts of the Carolinas, Georgia and northern Florida. These dangerous conditions will persist across many of these areas before beginning to lift toward the end of the workweek.

In the Carolinas, the City of Charlotte and Mecklenburg County officials warned residents and visitors to stay cool and safe.
“If you are out and about, be sure to find air-conditioned spaces, wear loose-fitting clothing, drink plenty of fluids, and avoid the midday heat,” County officials wrote on Facebook over the weekend.
Cooling centers are open at senior centers and some Charlotte-Mecklenburg library locations.
For the Southeast, heat relief won’t arrive until Friday, when a cold front will begin to slowly advance into the region, according to the FOX Forecast Center.
The cold front will not only bring cooler temperatures but an increased chance of rain.
With extreme heat in the forecast, anyone spending time outdoors should take steps to avoid heat exhaustion and heatstroke. Young children and babies, along with older adults, should avoid prolonged time outdoors. When outdoors, it’s important to drink plenty of water with electrolytes and spend time in the shade.
For your pets, if the sidewalk or road is too hot for your hands after several seconds, it’s too hot for your dogs to be walking on.
