As one grows stronger, the other weakens, but neither tropical system in the Atlantic poses any threat to the United States, experts said.
Neither the resurgent Tropical Storm Ophelia nor the fading Tropical Storm Philippe is expected to make landfall in Florida, making 16 named storms that have missed the peninsula this hurricane season.
Ophelia, which dropped off the map last week after winds died down significantly, was back as a tropical storm Wednesday. Churning about 200 miles east of the Leeward Islands, Ophelia had maximum sustained winds of 50 miles per hour and was moving northwest at about 3 mph, according to the National Hurricane Center.
Forecasters said the storm's projected path is too far east to threaten any land.
Tropical Storm Philippe, meanwhile, continued to move through open waters in the mid Atlantic. Experts said running into a large area of low pressure in the ocean will likely weaken the storm as it continues in a west-northwest direction.
Philippe, located about 930 miles west of the Cape Verde Islands off the Africa coast, was never expected to reach the United States, experts said.
The tropical storm, which seemed poised to become a tropical depression late Wednesday, will likely fizzle out in the open ocean, forecasters said.
The NHC has not issued any coastal watches or warnings.
