The historic polar vortex in the United States will end abruptly: they predict an unprecedented collapse

In Illinois, temperatures could rise 26.6 ° C in a few days.. In Michigan, melting snow, rain and an ice jam 27 kilometers (17 miles) long on the Muskegon River They could cause flooding. And around the central north of the United States, Warm weather forecasts will undoubtedly lead to more road and pipeline failures.

It is expected that the polar vortex will have an abrupt end with a rapid fusion that, according to experts, it could be unprecedented But the radical change of thermal clothes to shorts could cause its own problems.

"I think there has never been a case where we have experienced a change (so important) in temperature" in winter, said Jeff Masters, director of weather at Weather Underground. "The previous record cold spells have not dissipated so quickly … We are here, we are going to move to spring temperatures."

Thursday, the system has moved to the east, causing Arctic conditions in an area from Buffalo to Brooklyn. In western New York, a storm that dropped 51 centimeters of snow gave way to subzero temperatures and thermal sensations that punctured the face. In New York, about 200 firefighters fighting a fire in a commercial building were alternately warming themselves in trucks. At least 15 deaths have been linked to cold weather.

The drastic change in temperature will relieve the unbearable cold that forced the suspension of clbades, company closure and train paralysis. However, there will be potholes in roads and bridges weakened by the melting cycle. The same cycle can cause thunder of plumbing and pipes. Many vehicles will have air tires and the elbows of the wheels will be bent.

Joe Buck, Schmit crane service manager in Minneapolis and spent 20 hours abroad this week responding to broken vehicle calls, said that already receives calls to take Monday a delay of several hundred vehicles stopped.

"Sunday we will be at 4 ° C above zero", said Buck, who used 18 cranes day and night with thermal sensations going down to -45 ° C (-50 ° F).

The impact on the economy in general should not be very strong.

"It appears only marginally in the economic data", said Diane Swonk, chief economist at the accounting firm Grant Thornton, who worked at home because her Chicago office was closed due to weather conditions.

Mark Zandi, chief economist at Moody's Analytics, said that One of the reasons why intense cold has less impact on the economy is that, unlike a hurricane, people do not run out of electricity.

"People will stay at home, but they can do things like buy online"Zandi said. "Life goes on, it's a change in everyday life, but it's not a blow to the economy."
