Celebrate The 4th & World Cup In Philadelphia, With Heat Indices Expected At Or Near 110F Through This Coming Weekend
EDIT
A dangerous heat dome over the Eastern United States for the next several days is forecast to send temperatures into the triple digits, break records across multiple states and pose health risks for tens of millions of Americans.
In the Philadelphia area, the National Weather Service has warned that daily heat indexes could be as high as 110 degrees through Sunday. This is not the kind of heat event we see every year, the service wrote in an update this week, adding that the region could experience its hottest stretch since July 2011.
Of any city in the path of the furnace-like blast, Philadelphia might be the most prepared. The onetime capital of the nation, home to Independence Hall and the Liberty Bell, has long had one of the countrys most robust heat-response programs.
EDIT
A brutal stretch of heat in the summer of 1993 killed 118 people in Philadelphia, a tally higher than in other cities that were grappling with similar conditions. Many of the victims were among the citys most vulnerable poor, elderly or infirm. Some had no access to air conditioning and were found with their windows closed, the stifling heat probably worsening any health conditions. In the wake of that disaster, officials dug deeper into what went wrong. At the time, deaths were typically considered heat-related only when there were documented signs of hyperthermia defined as a core body temperature of 105 degrees or higher.
