There is a high chance of tropical formation over the northwest Caribbean Sea. The National Hurricane Center has now begun issuing advisories on Potential Tropical Cyclone 18.
The forecast does strengthen the system as it moves northeastward over Cuba and the Bahamas. The system is expected to be upgraded to tropical storm Philippe by the weekend.
Hurricane Hunters surveyed the storm Friday afternoon and said there was signs of strengthening.
The NHC said that with the signs of organization, a tropical depression or tropical storm is likely to form later Friday or Saturday as the system moves northward over the northwestern Caribbean Sea before turning northeastward by late Saturday.
If this continues to show organization, tropical storm watches and warnings will be issued for the Cayman Islands, western Cuba, and the northwestern Bahamas. Interests in the Florida Keys and South Florida should also monitor the progress of this disturbance, the NHC said.
Heavy rainfall is expected for the Cayman Islands, Jamaica, and Cuba over the next couple days. This weekend, rainfall can be expected to spread northward to South Florida and the central Bahamas.
