Heatwave continues to scorch 65 million people in the Midwest and Northeast of the United States | Extreme heat

About 65 million people were under heat alerts Friday in the Northeast and Midwest states, as an early-season heat wave in the United States continued to ravage the region.

Record temperatures were set in some areas, with combined temperature and humidity heat indices reaching 100F and 110F. Daily highs were broken in Maine, New Hampshire and Pennsylvania.

The National Weather Service warned that people without reliable air conditioning would be hardest hit. Across the Ohio River Valley, the Heat Hazard Index was at Level 4 – rated “extreme” for the next two days.

“This rare and/or long-lasting extreme heat, with little or no relief during the night, affects anyone without effective cooling and/or adequate hydration,” the agency said, adding that it was likely to affect “most health systems, industries and heat-sensitive systems”. “Infrastructure”.

With temperatures dropping only slightly at night, the national forecaster advised people to “drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check on your loved ones and neighbors.”

The sudden intensity of summer heat in the region is attributed to the northward movement of a high-pressure heat dome that had settled over Mexico and the southwestern United States in March.

It slowly moved across the north, breaking temperature records as it went. Climate group World Weather Attribution released a report Thursday saying the southern heat wave in late May was 35 times more likely to occur because of climate change and was 2.5F hotter.

In Texas, Gov. Greg Abbott issued a disaster declaration for 51 Texas counties after Tropical Storm Alberto flooded parts of the state. New Mexico also requested federal help after wildfires forced the evacuation of a town in the southern part of the state.

But forecasters predicted that colder, less humid air would move across the Northern Plains and upper Midwest over the weekend, then into the Northeast soon after.

Until then, it will nevertheless remain uncomfortable in certain regions. In the mid-Atlantic states, temperatures are expected to rise up to 100 degrees “with record temperatures possible.”

The heat caused infrastructure problems. In New York, hundreds of travelers were stranded on trains exiting Penn Station when a power outage and brush fire in the swampy area of ​​Secaucus, New Jersey, disrupted service.

US rail operator Amtrak said its trains would have to run at slower speeds due to the heat.
