DETROIT (USA), July 6: There's been no relief day or night from a scorching heat wave in the central, and the deadly temperatures were heading east on Friday after Midwest cities like Chicago, St. Louis and Milwaukee set record highs.    

So far at least 13 heat-related deaths have been reported by officials. When the air conditioner stopped in Ashley Jackson's Southfield, Michigan, home, so too did normal conversations and nightly rest.

''Inside the house it was 91 degrees. (33 Celsius) ... I wasn't talking to anybody. Nobody was talking to anybody,” said Jackson, 23, who works as a short-order cook in Detroit. “We mostly slept, but it was hard to sleep because of the heat. I probably got about four hours of sleep each night.''

The National Weather Service reported late Thursday that the record-breaking heat that has baked the nation's midsection for several days was slowly moving into the mid-Atlantic states and Northeast. That forecast followed excessive-heat warnings on Thursday for all of Illinois and Indiana, as well as parts of Iowa, Minnesota, Wisconsin, Missouri, Kentucky, Ohio and Michigan.

St. Louis hit a record high of 105 (40.6 C) on Wednesday and a nighttime record of 83 (28 C). In Wisconsin, the coolest Milwaukee and Madison got was 81 (27 C) in the early morning, beating previous records by 2 and 4 degrees respectively.

Temperatures at night didn't fall below 79 (26 C) in Chicago, 78 in Grand Rapids, Michigan, and 75 (24 C) in Indianapolis.

''When a day starts out that warm, it doesn't take as much time to reach high temperatures in the low 100 (38 Celsius),” said Marcia Cronce, a meteorologist with the National Weather Service. “You know it'll be a warm day when you start out at 80 (27 C) degrees.''

In Chicago on Thursday, the Shedd Aquarium lost power as temperatures soared to 103 (39.5 C) degrees, a record for July 5. Officials said emergency generators immediately kicked in and the outage never threatened any of animals, but several hundred visitors were sent back out into the heat.    The heat returned on Thursday and not even the setting of the sun brought respite as temperatures hovered around 90 degrees (33 C) downtown at 10 pm. Some visitors to the city made their way to Millennium Park to splash in the park's kid-friendly Crown Fountain.

''It's hotter here than it is in Arizona,” said Mary Dominis, who brought her daughter along to play in the water.

St. Louis officials have reported three heat-related deaths in recent days, and officials in the Chicago area said two people there may have died due to heat Wednesday.

It was hot enough to buckle a road in Chicago, where Columbus Drive cracked and bulged into a geologic-looking 5-inch (12-centimeter)-high driving menace. The city has closed the road for repairs. School officials in Chicago have cancelled summer school classes in 21 buildings without air conditioning due to the excessive heat.

Many cities have tried to help by opening cooling centres and extending the hours for their public pools. Compounding the high heat in Michigan was damage wrought by storms. About 157,000 homes and businesses across the state were without power early Friday.

Lack of electricity also is likely to compound the misery for many in the storm-ravaged East as the dangerous temperatures moved in. Late Thursday, nearly 230,000 people in West Virginia and more than 83,000 in Virginia were  with out power.—AP
