國家颶風中心
About a day before Dean developed, the National Hurricane Center advised interests in the northern and central Lesser Antilles to monitor the progress of the storm. Routine statements issued by the National Hurricane Center warned for the possibility of strong winds and heavy rains. However, because Dean formed after it passed the islands, no tropical cyclone warnings or watches were issued. The precursor disturbance dropped heavy rainfall on Saint Martin of around 5 inches (129 mm).
