Heat Index In US Northeast Tops 100; Girl Dies In Hot Car

August 29, 2018 - 3:34 pm

NEW YORK (WWJ/AP) - The dangerously high heat in the Northeastern United States has prompted emergency measures including extra breaks for players wilting at the U.S. Open tennis tournament.

In several states, children are being released from school early on Wednesday, and the elderly without air conditioning have been urged to go to cooling centers.

The National Weather Service says temperatures in the 90s combined with high humidity are pushing the heat index past 100. Authorities on Long Island say heat appears to be a factor in the death of an 11-year-old girl found in a vehicle with the windows closed.

At the U.S. Open in Queens, an extreme heat policy allows for 10-minute breaks between sets from the heat-absorbing courts.

And while northeast temperature are expected to ease into the 80s on Thursday, it'll just bit a bit cooler in the Midwest, forecasters say. 

After searing temps and high humidity triggered a Heat Advisory in metro Detroit earlier this week, WWJ AccuWeather Meteorologist Dave Bowers said a cold front coming through is to thank for some relief. 

The next couple of days will be nice, Bowers said, with highs in the 80s Wednesday, a cooler, comfortable Wednesday night and a sunny end to the workweek with lower humidity Thursday and Friday. However, the holiday weekend, he said, is expected to be a hot a muggy one.
