MIAMI (AP) — A weather system off Puerto Rico has the potential to become a tropical storm, forecasters said Sunday, a little more than a week after the Atlantic hurricane season ended. At 10:30 p.m. EST the system was about 425 miles east of Puerto Rico. It was moving west at about 15 to 20 mph and was expected to continue that general motion over the next day or two, according to the National Hurricane Center.

It could become a tropical or subtropical storm during the next 24 hours, forecasters said. Tropical storms have winds of at least 39 mph.
