SAN JUAN, Puerto Rico -

What was once Tropical Storm Chantal was downgraded Wednesday afternoon to a tropical wave.

Earlier Wednesday, the storm roared south of Puerto Rico on a path that will see it pass over the Dominican Republic and Haiti, where authorities warned of possible landslides and heavy flooding.

Chantal was becoming disorganized and a hurricane watch was discontinued for the Dominican Republic’s southern coast, according to the National Hurricane Center in Miami, Florida. However, a tropical storm warning was in effect for the Dominican Republic, Haiti, Puerto Rico, Turks and Caicos, and the southeastern Bahamas.

Earlier Wednesday, Chantel's maximum sustained winds had decreased to 45 mph as the storm was cruising west northwest at 29 mph about 260 miles west southwest of San Juan. 

Its path, likely taking it over the mountains of Hispaniola, and later, Cuba, had the National Hurricane Center forecast the system would lose its tropical strength before nearing the Florida peninsula.
