Climate scientists say a coming ‘polar vortex’ could mean a brutal winter on the East Coast.

The vortex is caused by a rapid warming in the stratosphere, sending cold air spilling to Earth, resulting in bitter wind storms that could last for weeks.

But not all scientists are in agreement over when the vortex will strike. Some say it’s likely to happen shortly after Christmas, while others say later. The later the vortex arrives, the less severe it will be.
