MIAMI – A tropical depression has formed south of Puerto Rico, resulting in storm warnings.
Forecasters at the U.S. National Hurricane Center in Miami say the depression was centered about 130 miles (210 km) south of San Juan, Puerto Rico on Wednesday afternoon.
Maximum sustained winds were 35 mph (55 kph), and forecasters expected it to become a tropical storm by Thursday.
Tropical storm warnings were issued for Puerto Rico and part of the Dominican Republic.
Forecasters expected the storm's center to pass between the islands and eventually curve back to the northeast away from the U.S. mainland. However, storm paths are difficult to predict accurately days in advance.
