Tampa breaks the heat record while the heat dome cooks the east of the United States

Tampa Casse 100 degrees F for the first time that the heat waves cooked in the east of the United States

The recordings are starting to fall into the continuous heat dome which covers much of the east of the United States

Assistance forecasts for July 29, 2025. The NWS is an experimental index on nuclear colors which offers a planned risk of heat -related impacts to occur over a period of 24 hours.

In the United States, more than 250 million people – three -quarters of the population – present a moderate, major or extreme risk of heat effects on July 28, according to the National Weather Service of the National Weather of the National Oceanic and Atmospheric Administration. Warnings come as a heat dome continues to stifle the east of the United States – and records are starting to fall under the oppressive heat.

The most surprising is perhaps that, on July 27, the current heat dome pushed Tampa, Florida, in three-digit Fahrenheit since the start of surveillance in the 1890s, according to the Tampa Bay Times. “We are often more than 90 years old – for three, four months a year, almost every day, he exceeds 90,” said Tyler Fleming, meteorologist at the Tampa Bay office of the National Weather Service. “But reaching 100 has a lot of warmth, so it never happened in Tampa’s recorded history.”

Surrounded by water, the Tampa – and the Florida as a whole – are generally cursed with enough humidity to maintain the overall temperature of the air, because a thermometer is a little lower. It takes a lot of energy to heat the water (think about how long it takes to bring the water to a boil on the stove), it is therefore more energy to heat the wet air at a given temperature that it is not necessary to heat the dry air at the same point, explains Fleming.

He says that there was no special factor that caused Tampa’s heat record on Sunday beyond the end of the current situation. “We were close to several times; We have been 99 several times before, ”explains Fleming. “It was just a strong heat wave – it was just enough to push us on the edge.”

Tampa is the most prominent city to see a record heat fall. But the current extreme heat fight has linked record temperatures in several other cities, including Jacksonville, Florida, and Charlotte, NC

Climate change increases the chances of beat heat recordings everywhere, as global temperature is now higher and extreme heat events become more frequent and warmer and last longer.

A dome of brutal heat has stifled a large part of the east of the United States since last week, with the worst conditions starting in the Midwest, going to the east coast and then settling in southeast. The heat dome is the result of a remarkably significant peak of high pressure that has hidden the region. “When this high pressure is above the head, it pushes the air down,” explains Fleming. “While the air flows, it compresses and warms up.”

The current heat dome should persist for several days until the high pressure system migrates to the west, which says Fleming should send the region to what it calls “a more typical summer model”.

But for the moment, huge parts of the country remain in danger of the stifling heat. The Heatrisk NWS card calculates the number of people exposed to different heat risk categories. On July 28, 16 million people were at extreme risks, which NWS describes as “extreme and / or long -lasting heat without relief overnight”; Additional 135.9 million are at major risks. The card estimates that on July 29, more than 12 million people will remain at an extreme risk and nearly 150 million will be at a major risk. And on July 30, nearly 115 million people should be at major or extreme risks. The high risk widespread will not start to decrease before July 31.
