Philadelphia ? Americans dipped into the water, went to the movies and rode the subway just to be in air conditioning on Saturday for relief from unrelenting heat that has killed at least 30 people across half the country. The heat sent temperatures soaring over 38?C in several cities, including a record 40.5?C in Washington, St Louis 41?C, and Indianapolis 40?C, buckled highways and derailed a Washington-area train even as another round of summer storms threatened.
The heat sent temperatures soaring in more than 20 states.
At least 30 deaths were blamed on the heat, including nine in Maryland and 10 in Chicago, mostly among the elderly. Three elderly people found dead in their houses in Ohio had heart disease, but died of high temperatures in homes lacking power because of recent outages, officials said. Heat was also cited as a factor in three deaths in Wisconsin, two in Tennessee and three in Pennsylvania.
Officials said the heat caused highways to buckle in Illinois and Wisconsin. In Maryland, investigators said heat likely caused rails to kink and led a green line train to partially derail in Prince George?s County, Maryland, on Friday afternoon. No one was injured, and 55 passengers were safely evacuated.
Thousands of mid-Atlantic residents remained without power more than a week after deadly summer storms and extreme heat struck the area, including 120 000 in West Virginia and about 8 000 in the suburbs around Baltimore and Washington, DC In the Washington area, the utility company Pepco asked customers to conserve power, saying the heat was stressing the system.
?This is becoming a black swan of heat waves, in the sense that it?s such a long heat wave, such a severe heat wave and encompassing such a large area,? said Chris Vaccaro, spokesman for the National Oceanic and Atmospheric Administration.
