US heat dome causes dangerous conditions for more than 100 million people | US news
More than 100 million people in the United States will face dangerous conditions at the weekend as a heat dome that drives most of the country’s center to the east.
On Friday, Portland, Wilmington from Mainine, from North Carolina, all over the north -east coast, in some places day heat index temperatures were over 10 to 15F of average.
According to the National Weather Service (NWS), night temperatures will be transmitted in a very hot and oppressive way.
Some of them are expected to break heat for the northeast until Friday night, some of which are severe, and this weekend will continue to ride more south with the most permanent and dangerous conditions expected in the Southeast and Tennessee Valley.
The heat index is how the temperature feels considering humidity. New York City is expected to be slightly higher than the 106F heat index under the 106F heat index on Friday afternoon.
In the southeast, the heat index may exceed 115F, which can risk people’s health and lives without adequate cooling and/or adequate hydration. “This will be a long -term heat wave, very little or night relaxation and high levels of humidity, which will lead to an increasing danger,” the Federal Service said.
High temperatures and high humidity increase the risk of heat depletion, heat diseases and death, which is at the highest risk of children, elderly people and those with existing physical and mental health conditions. Outdoor workers – gardeners, builders, farmers and delivery workers – are particularly vulnerable with people who have no declaration and those with substance use problems.
A heat dome It is a certain phenomenon in which hot air is stuck in a region by a stopped high -pressure system and causes high temperatures on the ground. Due to the jammed high pressure system, the sun’s rays directly hit the ground with a slight cloud cover and increased the heat further.
Heat domes Cause heat waves – Thanks to the climate crisis, it becomes more frequent – heat waves without heat domes. Climate scientists have found that heat domes warmed due to the global heating caused by people burning fossil fuels.
And while the last dome in the USA moves slowly, in some parts of the middle day, it continues to cause dangerous conditions to the Mississippi Valley, and there are still heat warnings from Oklahoma to Western Virginia.
Some southern states, called the corn belt, where the Middle -west and most corn grown, exacerbates a phenomenon known as Egyptian sweat and can increase the heat index by 10F. This is due to the pores under the Egyptian leaves where oxygen and water vapor are released in an interview, Iowa’s state climatologist. With CBS News.
Meteorologists also foresee as much flash of Flash from Northeast Kansas to most Indiana and in the regions of New England, Northern Middle Atlantic and Northern Dakota. By the way, dry, windy conditions I triggered a red flag Forest Fire Warning for the Sections of Utah and Oregon.
