NEW YORK (AP) - The East Coast roasted under an unrelenting sun Tuesday as record-setting temperatures soared past 100 from Virginia to Massachusetts, utility companies cranked up power to the limit to cool the sweating masses and railroad tracks were so hot commuter trains had to slow down.
"It's brutal," said construction worker Pat McHugh, 49, his face shiny with sweat, as he took a break in New York City. "Worst heat on the job in 10 years.
The temperature broke records for the day in New York, where it hit 103, and in Philadelphia, where it reached 102.
It was also over 100 in cities from Richmond, Va., to Boston, and Providence, R.I., and Hartford, Conn., also set records.
"It's safe to say this is one of the hottest days in about a decade for many locations in the Northeast and even inland," said Sean Potter of the National Weather Service. "You'd go back to 2001 or maybe 1999 to find a similar heat wave."
With people cranking up the air conditioning, energy officials said there was tremendous demand for electricity, but the grid didn't buckle.
Few power problems were reported and the operators of the regional electrical systems that serve the Mid-Atlantic, New England and New York said they had ample capacity.
Usage appeared to be falling just short of records set throughout the Northeast during a major heat wave in 2006.
"Hydrate," President Barack Obama reminded a group of reporters as they left the Oval Office at the White House.
Meteorologists in some places began calling the hot stretch a heat wave, a phenomenon defined in the Northeast as three consecutive days of temperatures of 90 or above. New Jersey's largest city, Newark, handily beat that threshold, hitting 100 for the third day in a row. Temperatures in the Mid-Atlantic region are expected to be in the high 90s to 100 again today.
It was so hot that even machines had to slow down. Transportation officials cut the speed of commuter trains in suburban Washington when the tracks got too hot. Extreme heat can cause welded rails to bend under pressure.
Workers at the Marine Mammal Stranding Center in Brigantine, N.J., used tubs of ice cubes to help four sick or weakened seals keep cool.
It wasn't much easier on animal lovers. In Massachusetts, Katie Wright was determined to follow through on her promise to take her children to a zoo.
"It's pretty ridiculous," Wright said as her 3-year-old son Jackson and 2-year-old daughter Emery watched owls and hawks at the Massachusetts Audubon's Drumlin Farm Wildlife Sanctuary in Lincoln. "But we wanted to get out, so we brought hats, sunscreen, extra water and then promised the kids lunch at an air-conditioned restaurant."
At his Manhattan newsstand, a steel kiosk that soaks up sun like a sponge, vendor Sam Doctor said the only way to keep cool was to splash his head with water, but he acknowledged that his system wouldn't last. Both of his soda-cooling refrigerators had already conked out by midmorning.
"When it's 100 degrees out there, it's 110 in here," he said, still smiling as he served customers.
In Philadelphia, where the temperature was in the 80s before 7 a.m., 45-year-old Davey Adams waited in a subway station that was stagnant even before the morning commute began in earnest. He had spent the weekend in air-conditioned bliss at his son's house in New Jersey but had to return to his job Tuesday as a forklift driver in a warehouse.
He said he planned to use "cold water and a washcloth" draped over his head to keep cool.
In New York, 13 firefighters were treated at a hospital after suffering dehydration and exhaustion while battling a blaze in Queens. The 42-year-old lieutenant governor of Massachusetts spent Monday night in a hospital after marching in five parades in 90-degree heat.
Deaths blamed on the heat included a 92-year-old Philadelphia woman whose body was found Monday and a homeless woman found lying next to a car Sunday in suburban Detroit.
Even Queen Elizabeth II, a familiar visitor to exotic and steamy places, was subject to the grueling heat on her first visit to New York City in more than three decades.
Dressed in a summery floral dress and hat, the 84-year-old monarch paid tribute to the victims of the Sept. 11 attacks, placing a wreath of flowers and chatting with victims' relatives.
"She's beautiful. She looks like she could be anybody's grandmother," said Debby Palmer, who lost her husband, Battalion 7 Chief Orio Palmer. "And she looks like royalty, because we're all sweating and she was quite the lady - no sweat whatsoever! Her lipstick was just so."
There was no end in sight.
The hot air is "sitting over the top of us, and it's not really going to budge much for the next day or two," said Brian Korty, a meteorologist with the National Weather Service in Camp Springs, Md. After that, he said, a system coming in off the Atlantic Ocean would bring in cooler weather.
A certain segment of the public might look at the thermometer and blame global warming, but the two things aren't necessarily related, said Gavin Schmidt, at the Center for Climate Systems Research at Columbia University.
"One winter, one heat wave, one snowstorm is not significant. You need statistics over a decade," he said, noting that day-to-day weather and global temperature are two different things.
That said, he added, "the planet is getting warmer. 2000-2009 was the warmest since the 1850s. And the last 12 months seem to be the warmest."
So get used to it.
