Sweltering heat settles in

NEW YORK – From South Dakota to Massachusetts temperatures surged to potentially dangerous levels Wednesday as the largest heat wave of the summer stretched out and stagnated, with relief in many parts of the country still days away.

Most states in the U.S. had at least one region where the temperature hit 90 degrees, according to the National Weather Service, though the worst heat was in the Midwest to Northeast. Humid air just made it all feel worse, with heat indexes in some places over 100.

In New York City, where it was 96 degrees, sidewalk food vendor Ahmad Qayumi said that by 11 a.m., the cramped space inside his steel-walled cart got so hot, he had to turn off his grill and coffee machine.

“It was just too hot. I couldn’t breathe,” he said, turning away a customer who asked for a hamburger. “Just cold drinks,” he said.

Amid the heat, officials in Washington, D.C.’s Maryland suburbs worked to keep a failing water main from cutting off hundreds of thousands of people, just when they needed it most. People in Prince George’s County were asked not to run their faucets, water their lawns or flush toilets to keep the water system from emptying during emergency repairs.

It was hot enough to buckle highway pavement in several states. Firefighters in Indianapolis evacuated 300 people from a senior living community after a power outage knocked out the air conditioning.

Officials blamed hot weather for at least one death. A 78-year-old Alzheimer’s patient died of heat exhaustion after wandering away from his northern Kentucky home Tuesday in temperatures that rose to 93 degrees.

Limited relief, in the form of a cold front, was expected to begin dropping south from Canada starting today, before sweeping through the Midwest and into the Mid-Atlantic and Northeast regions by Saturday.
