Overview

  • More than 80 million Americans remain under active heat alerts across the Southeast, Midwest and Mid-Atlantic, with heat indices climbing into the triple digits.
  • The National Weather Service has issued widespread heat advisories, watches and extreme heat warnings from central Florida through Virginia and into the Great Lakes.
  • A slow-moving cold front is spawning scattered severe thunderstorms and flood advisories in regions including Northeast Ohio and New York, bringing locally heavy rain and gusty winds.
  • High humidity is amplifying health risks, prompting officials and OSHA to urge residents to stay hydrated, seek air-conditioned shelter and check on vulnerable populations.
  • Forecasts call for a midweek pattern change as cooler, less humid air moves in, offering relief from the life-threatening heat wave.
