Tropical Storm Sara has formed in the Caribbean Sea and is forecast to continue strengthening, according to the National Hurricane Center.

A somewhat rare November storm system is gathering steam in the Caribbean Sea. Tropical Storm Sara will eventually make a turn to the east and Florida. Lots of factors in play but Tropical Storm Sara is expected to form this week and could become a major hurricane threatening the US next week.

The National Hurricane Center is also asking residents of the eastern Gulf Coast, including Florida, to monitor the storm closely since it has the potential to reach the US.
