With Hurricane Helene having turned into a post-tropical cyclone but still dumping rain in the Ohio Valley and Southeast U.S., the National Hurricane Center turned its attention to two developing systems with growing chances to form into the season’s next tropical depression or storm while also keeping track of Hurricane Isaac and Tropical Storm Joyce in the Atlantic.

Just days after Hurricane Helene made landfall, the National Hurricane Center is warning residents on the Gulf Coast to monitor another tropical system.

A low-pressure system in the eastern Caribbean has a medium chance of developing into a tropical depression over the next seven days, according to the National Hurricane Center in Miami.
