A tropical disturbance is moving over Puerto Rico and the Dominican Republic, leaving very large amounts of rainfall behind. The Virgin Islands and surrounding islands report rainfall totals of up to 8 inches (200 mm). The National Hurricane Center in Miami is warning that there is a high (60%) likelihood that this could turn into tropical storm Bonnie by Thursday. The projected path could take the system into Florida in a couple of days' time.
Just to reiterate: no tropical cyclone has formed and it is not certain that one will actually form.
Please monitor the NHC's output for further updates.
