If you’re planning a trip to the United States or currently residing there, it’s crucial to prepare for extremely cold weather depending on your location. The National Weather Service (NWS) has alerted that a polar vortex is set to hit America soon, bringing an icy wave across various regions.
understanding the polar vortex
This term may sound like something out of science fiction, but it is a well-documented meteorological phenomenon. The polar vortex describes a low-pressure area forming over the poles each winter at approximately 18 miles altitude. This cold pocket stretches from the mid-troposphere (5 to 7 miles altitude) up to the stratosphere (6 to 31 miles). It comes with strong west-to-east winds that drive the formation of a powerful jet stream.
- Theoretically focused at the poles.
- Practically observed as unstable.
The polar vortex can shift southward, releasing cold air masses that cause significant cold waves in North America, Russia, and parts of Europe.
frigid temperatures expected in the u.s.
The NWS has closely monitored this instability, predicting that early winter will be especially harsh throughout January 2025, particularly on America’s East Coast. Sub-zero temperatures are anticipated in Florida and Texas, potentially dropping as low as 17°F. Further north, residents in Minnesota might experience bone-chilling lows around -13°F.
- Snowfall and freezing winds could disrupt daily activities nationwide.
a look back at past events
The last major unstable polar vortex impacted the U.S. in 2022 with dire consequences. In addition to fatalities directly linked to the storm‘s impact during Christmas time, about 1.5 million homes lost power across both America and Canada. The NWS had warned of potential lows reaching -49°F during this period.
