As the third named storm to emerge during November, Tropical Storm Sara serves as a reminder that the Atlantic hurricane season hasn’t quite ended.

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.

This November surge follows Tropical Storm Patty and Hurricane Rafael, making it an unusually active final month for the hurricane season, which typically produces only one named storm every year or two. Experts cite warm ocean temperatures as a possible factor, though the role of climate change in extending hurricane seasons remains debated.
