**Breaking News: Millions Face Life-Threatening Heat Warnings Across the U.S.**

A scorching heat wave has gripped the United States, putting over 129 million people in more than 20 states under urgent heat advisories. As temperatures soar, the National Weather Service warns of life-threatening conditions, with heat indices potentially reaching a staggering 105 degrees Fahrenheit. Cities like New York are bracing for extreme heat, with temperatures expected to hit the high 90s this afternoon, making outdoor activities perilous.

Meteorologists are sounding alarms about a “heat dome” phenomenon, a massive ridge of high pressure that traps heat and creates oppressive conditions across the central U.S. New Yorkers are already feeling the impact, with subway systems turning into sweltering tunnels as temperatures down below climb to 82 degrees. Residents are urged to stay hydrated and avoid prolonged exposure to the sun, as the situation is expected to worsen throughout the day.

But the heat isn’t the only concern. Severe weather is brewing in Kansas, Nebraska, and Missouri, where flash flood warnings are in effect due to heavy rainfall predicted to total 2 to 4 inches. This slow-moving storm system poses a significant risk of localized flooding and damaging winds, with authorities on high alert.

Adding to the chaos, a disturbance in the Gulf of Mexico is being monitored for potential tropical development, threatening to unleash heavy rain and thunderstorms from Florida to Texas. Hurricane Hunters are set to investigate this system as it moves inland, posing yet another layer of risk for communities already grappling with extreme weather.

As millions brace for the heat and storms, officials stress the importance of taking precautions. Stay indoors if possible, keep cool, and remain vigilant as conditions rapidly evolve. This is a critical moment—stay tuned for updates as the situation develops.
