A "life-threatening" polar vortex will bring temperatures as low as -50℃, putting 235 million people at risk.

Meteorologists have issued an urgent warning about a "life-threatening" polar vortex that will bring astonishing cold temperatures—down to -50℃. Researchers have also cautioned that around 235 million people living in the risk zone are in danger, reports Daily Mail.

It is expected that the low temperatures may last for about three days, straining heating systems and power grids. Local authorities are also considering the possibility of school closures. Additionally, experts warn of a high risk of frostbite, hypothermia, and impacts on the immune system.

Experts note that the severe cold will last for approximately three days and will affect regions from the Gulf Coast to New England, the Great Lakes, and the Midwest. A rare winter storm is also anticipated to bring snow and ice to the southern United States.

According to the National Weather Service (NWS), winter storm Enzo is expected to hit states along the Gulf Coast, including southern Texas, Louisiana, Mississippi, Alabama, Georgia, and South Carolina, as well as the Florida Peninsula. Experts have warned that the winter storm will bring a mix of snow, sleet, and freezing rain.

"Life-threatening" low temperatures caused by the polar vortex are likely to fuel storm Enzo, potentially bringing record-breaking cold. Meteorologists note that temperatures may feel as low as -12℃ to -1℃. However, scientists believe the core of the cold will descend upon the Midwest.

According to senior meteorologist Adam Douty, much of this extreme cold is actually due to gusty winds capable of making the perceived temperatures drop significantly below zero. Experts warn that in areas experiencing windy conditions, temperatures may feel an astonishing -40 to -50℃.

Experts emphasize that during this period, it will be incredibly cold outside, and anyone who decides to venture outdoors is likely to suffer frostbite on exposed skin within just a few minutes. The risk of cold-related illnesses such as frostbite, hypothermia, and damage to the lungs or immune system will be high in areas exposed to these extremely cold winds.

During this time, researchers do not recommend leaving indoor spaces. However, if going outside is unavoidable, additional protective measures against life-threatening temperatures should be taken. Here are some expert tips:

• cover the skin;
• wear multiple layers of clothing;
• go indoors to warm up.
