(WMBF) - The WMBF News First Alert Weather team has been keeping an eye on the small chance of a subtropical system developing north of the Bahamas.

While the team says there will be no hurricane or major tropical storm, tropical characteristics are possible, which could bring increased surf, high rip risk and showers along the Carolina coast.

What is a subtropical cyclone?

An area of low-pressure that has characteristics of both tropical storms and winter-like storms.

The difference is important, since tropical systems have the potential to quickly grow into hurricanes, while extratropical or subtropical storms do not.

Like tropical storms, subtropical storms originate over tropical or subtropical waters, and have a closed surface wind circulation around a well-defined center.

In addition, these storms have well organized, showers and thunderstorms.

If the subtropical storm remains over warm water for several days, it may eventually become fully tropical, and be called a tropical storm.

A subtropical storm typically has a large, cloud free center of circulation, with very heavy thunderstorm activity in a band removed at least 100 miles from the center.

In comparison to tropical storms, these systems generally have the strongest winds occurring relatively far from the center (usually greater than 60 miles), and generally have a less symmetric wind field and distribution of showers and storms.
