More than 130 million people are bracing for oppressive heat as heat advisories and warnings have been issued for the Southeast and Midwest. This extreme heat wave, fueled by a heat dome, is causing dangerous conditions that could break records, with temperatures soaring into the triple digits. Many areas are experiencing a combination of high heat and humidity, prompting officials to advise residents to limit outdoor activities and stay hydrated. Severe thunderstorms are also a possibility later today, adding to the mix of weather challenges. As these intense heat conditions persist, some areas could experience relief, but for now, a significant portion of the Eastern U.S. remains under extreme heat alerts.
