A depression has strengthened into Tropical Storm Lisa over the eastern tropical Atlantic.
The storm's maximum sustained winds on Tuesday were near 40 mph. The storm is centered about 430 miles west of the Cabo Verde Islands. The U.S. National Hurricane Center says some additional strengthening is forecast during the next 48 hours.
Also in the Atlantic, Tropical Storm Karl is forecast to begin strengthening in another day or two. Its maximum sustained winds have decreased to near 40 mph. Karl is centered about 530 miles east-northeast of the Leeward Islands and is moving west-northwest near 17 mph.
Both storms are expected to head toward the north over the Atlantic. As of now neither storm poses a threat to South Florida.
