The AccuWeather team warns that the period from Wednesday morning to Wednesday evening will probably bear the biggest threat of extreme weather that the US has seen this year.
It was already a chaotic first three months of 2025, with waves of winter storms, tornados and floods that pummelen most of the country.
In February, a 'Polar Vortex -ineen deposit' left a mess in much of the US, which brought feet of snow, landslides and flee to millions of Americans.
A 'polar vortex collapse' in fact means the large, cold swirl of air that is constantly turning around around the North Pole, starts to wiggle or break apart, causing cold arctic air to fall to places such as the US or Europe.
Meteorologists noted that the Jetstroom brought that cold air from the north was locked up in an almost perfect straight line over America, who went from west to East that entire month.
This non -stop weather system continued to feed winter storms, which developed in the plains and the midwest and fell into the northeast and New England.
Things did not get better in March, because another Polar Vortex collapsed in the middle of the month, predictors had a late start to the spring.

Predictors say that different areas are confronted with a great chance of seeing a tornado developing on Wednesday, including Arkansas, Tennessee and Kentucky

Between six and 12 centimeters of rain fell in parts of southern Texas for a period of 24 hours, according to the National Weather Service.
This week's downpour throughout the country could also bring fatal conditions, whereby the AccuWeather team that projects intense rainfall, will bring flood risks in southern Texas and Louisiana and so far to the north like Michigan and Pennsylvania.
Van thunderstorms are still expected to be intense to Friday and Saturday, so that more hail and gusts of wind bring between 60 and 70 MPH.
While the land lanes persist on the weekend, more than 46 million people will be affected in the central US, and at least 13 million will be within a high to extreme liquid risk zone, AccuWeather reported.
