Heat Dome Update: Dangerous Heat Expands Across the U.S. [PdJAcU8FmRK]
A massive heat dome is expanding from the Midwest into the East, putting around 200 million Americans at risk for dangerous heat through the Fourth of July period. Heat index values could approach or exceed 105–110°F in many areas, while very warm overnight lows may bring little relief and raise health risks for vulnerable people. Stay hydrated, limit midday exposure, check on elderly neighbors, protect pets, and monitor local alerts as forecasters also watch the Gulf and southern Atlantic for possible storm development. #HeatDome #ExtremeHeat #WeatherUpdate #HeatWave #PublicSafety
