As of midnight last night, the Village of Key Biscayne and the Miami-Dade County Office of Emergency Management continue to monitor potential tropical cyclone nine, about 235 miles SE of the Leeward Islands, in the Atlantic Ocean. If this system further develops, it could potentially be named Isaias.
Current location: 14.6N / 59.4W (Approximately 1,600 miles SE of Miami-Dade County)
Maximum Sustained Wind Speed: 40 MPH
Forward Speed: 25 MPH
Forward Direction: WNW
Potential for further development or weakening: The system is forecast to move through the Leeward Islands today, and near or over the Virgin Islands and Puerto Rico tonight, and near or over The Dominican Republic and Haiti on Thursday. Some strengthening is expected during the next 48 hours, and the system is forecast to become a tropical storm today. The long-range track and intensity forecasts are more uncertain than usual since the system does not yet have a well-defined center.
Potential Impact for Miami-Dade County: 30-40% chance of tropical storm force winds across the metro and coastal sections of South Florida in the next 5 days. Tropical storm force winds could arrive as early as Friday but more likely on Saturday.
