Tropical Storm Fred is expected to form today, prompting tropical storm watches and warnings across the northern Caribbean.
If it forms, Fred will be the 6th named storm of the 2021 Atlantic hurricane. The disturbance is currently a potential tropical cyclone and the US National Hurricane Centre says satellite imagery shows it has become better organized since yesterday.
It is forecasting it will strengthen into a tropical storm this evening.
The system is moving west-northwestward at 18 mph with sustained winds of 35 mph. As it continues to progress through the Caribbean, the potential cyclone will bring the threat of flooding, mudslides, and dangerous winds to the islands in the region.
Tropical storm conditions are expected in portions of the U.S. Virgin Islands and Puerto Rico beginning this afternoon, and in the Dominican Republic by Wednesday. Tropical storm conditions are possible in northern Haiti and the southeastern Bahamas by late Wednesday.
Tropical storm warnings are in effect for Puerto Rico, including Culebra and Vieques, the US Virgin Islands, and parts of the Dominican Republic on Tuesday. Tropical storm watches include Martinique and Guadeloupe, Saba and St. Eustatius, the Dominican Republic on the north coast from Cabo Frances Viejo to the border of Haiti, parts of Haiti, Turks and Caicos and the southeastern Bahamas, according to the NHC.
