Extreme heat blankets U.S., with almost 160 million under alerts from Texas to Maine

In Paterson, New Jersey, more than 100 people needed treatment during two open -air graduation ceremonies on Monday while the heat index rose to 107 degrees. Monday evening, mayor André Sayegh declared the state of emergency due to high heat and canceled all recreational activities.
More than 60 record temperatures were set across the country on Monday, and more anticipated this week from the Southeast in New England.
Preliminary daily records were established Tuesday in New York (which reached 99 degrees), Philadelphia (which has reached 100 degrees for the first time since 2012) and Raleigh, in North Carolina (which reached 100 degrees).
New monthly records in June of all time were established in Boston (101 degrees) and Providence, Rhode Island (100 degrees) and Newark, New Jersey, equaled its June 103 degree record.
Conditions should remain stifling during evening hours, according to the National Weather Service.
“The night stockings should fall in the 1970s, with urban centers along the East Coast which are struggling to fall below 80 degrees at night,” the weather service said in its short -range forecasts on Tuesday.
The stifling conditions are caused by a high pressure crest that is parked in the east of the United States. These systems are known as the heat domes because they trap hot air in a region, which increases temperatures for prolonged periods.
A certain relief is later scheduled for this week, before the weekend, but the heat and humidity will continue to skyrocket in the coming days.
“The most important cumulative heat impacts are anticipated through the middle of the Atlantic until Thursday and the east of Ohio Valley until Friday, leading to several consecutive days of oppressive heat,” said meteorological service.
Anyone is sensitive to heat -related diseases or deaths, but excessively hot and humid conditions – especially for days – are particularly risky for children, people with pre -existing health problems, the elderly and people working outside. These health impacts are a significant concern because heat waves become more frequent, intense and more durable due to climate change.
While the eastern half of the country cooked under the heat of heat, serious storms could strike parts of Wyoming, Colorado, South Dakota and Nebraska. Strong precipitation and floods are also possible for a large part of the New Mexico and the extreme southwest of Texas.
