Record subzero temperatures have gripped much of the U.S. this week, with more wintry weather in the forecast.

A "bomb cyclone" is bearing down on the East Coast bringing snow and icy conditions with it all the way down to Florida. The storm has already caused road closures in Georgia and some flight delays throughout the Southeast.

Rona Gromet, 61, disembarked from a Caribbean cruise in Charleston, South Carolina, only to arrive home to the states in a blizzard. A California resident, Gromet was forced to take shelter in a hotel, along with hundreds of other cruise passengers. Her Wednesday afternoon flight has been delayed until Friday at the earliest.

"Everybody is trying to get hotel rooms. Everyone is looking around for food – it's just, it's really crazy," Gromet said.

The frigid temperatures have been blamed for at least 12 deaths. Forecasters expect these cold temperatures and wintry conditions to worsen over the next few days.
