The Atlantic Ocean is normally a breeding ground for hurricanes that threaten the United States during the summer months, but a couple thousand miles to the south, storms in the Southern Ocean can be even more perilous.

One such storm was captured by satellites Wednesday, spinning over the open ocean north of Antarctica. In the Southern Hemisphere, it's the end of summer, and storms of this size and magnitude occur frequently in the Southern Ocean, according to weather.com senior meteorologist Jon Erdman.

These storm systems are often hundreds or even thousands of miles wide , and central pressures bottom out at extremely low levels. Erdman said the European forecast model initialized a central pressure between 941 and 943 millibars in its center for this storm Wednesday, a similar level to a storm system that pounded Europe during Christmas 2013. In that storm, at least five people were killed, hundreds of thousands lost power and many travelers spent Christmas Day stranded at European airports, unable to fly through the stormy weather.

According to Weather Underground's Christopher Burt, a French expedition based in Port Martin, Antarctica measured an average 24-hour wind speed of 108 mph on March 21-22, 1951, a record high for anywhere in the world.
