Hurricane Season Could Start Early for 7th Year in a Row With the Potential Formation of Subtropical Storm Near Bermuda The Weather Channel 3 hrs ago Jonathan Erdman Replay Video UP NEXT Atlantic hurricane season could be off to an early start for the seventh straight year with the potential formation of a subtropical storm near Bermuda. The National Hurricane Center (NHC) says a non-tropical low-pressure system located several hundred miles to the east-northeast of Bermuda has a high chance of forming into a subtropical storm Friday. A subtropical storm has features of both tropical and non-tropical systems, including a broad wind field, no cold or warm fronts, and generally low-topped thunderstorms displaced from the center of the system. They are named from the same list the NHC uses for tropical storms and hurricanes.
