High temperatures and humidity across north-eastern coast increase risk of heat exhaustion, illnesses and death
More than a 100 million people in the US will face dangerous conditions over the weekend as a heat dome which has scorched much of the center of the country nudges eastward.
Heat advisories were in place on Friday all across the north-eastern coast from Portland, Maine to Wilmington, North Carolina, with the daytime heat index temperatures 10 to 15F above average in some places.
Overnight temperatures will also be very warm and oppressively muggy, according to the National Weather Service (NWS).
While thunderstorms, some of them severe, are expected to break the heat by Friday night for the north-east, heat and humidity will continue to build further south with the most persistent and dangerous conditions expected across the south-east and Tennessee Valley this weekend.
