HOLT, Fla., Aug. 18, 2017–Tropical Storm Harvey will move through the Windward Islands and into the eastern Caribbean Sea today before traveling into the central Caribbean Sea Saturday.
The 2 p.m. EDT update by the National Hurricane Center expects Harvey to remain a tropical storm, rather than grow to hurricane strength, as it crosses the Caribbean Sea and makes landfall in South America.
The center predicts Harvey will further degrade to a tropical depression as it passes over the Yucatan peninsula before entering the Gulf of Mexico next Wednesday where it could pick up energy over the warm Gulf waters.
Meanwhile, in the Atlantic Ocean, conditions are looking less favorable for Invest 92 to develop into a tropical depression, while conditions are forecast to become more so for the system in the far-eastern Atlantic.
Invest 92, located about 600 miles east-northeast of the Leeward Islands continues to show signs of organization, but wind shear will likely keep it from developing as it travels west-northwest at about 20 mph during the next few days.
The NHC gives it a 60 percent chance of further formation during the next 48 hours before upper-level winds become less favorable.
The tropical low located over the far eastern Atlantic Ocean is several hundred miles west of the Cabo Verde Islands.
Environmental conditions are forecast to become more favorable for some development early next week while the system moves west-northwest to northwest at about 20 mph.
Formation chance through the next 48 hours is low, but as it advances through the next five days the possibility of further development rises to 40 percent.
