Hurricane forecasters are watching a new potential storm as the Atlantic hurricane season motors past its halfway point. So far, the season hasn't logged an exceptional number of storms, despite early warnings of a hyperactive season.

The next tropical storm could come from a slow-spinning system in the northern Caribbean, according to the National Hurricane Center.

The chances that a new named storm could form in the Caribbean and drift into the Gulf of Mexico next week are growing. As of Thursday afternoon, the hurricane center upped the possibility of strengthening to 40% within the next seven days, with no chance within the next two days.
