On December 10, the Tropical Prediction Center gave out a gale warning for waters north of the Lesser Antilles, Puerto Rico, and the Dominican Republic, in association with the disturbance that would later become Olga. Right after it being classified as a subtropical cyclone, the government of the Dominican Republic gave out a tropical storm warning from Cabo Engaño along the north coast to its border with Haiti; a tropical storm watch was also issued along the southern coastline to near Santo Domingo. Because winds were well to the north of its center, a tropical storm warning was not issued for Puerto Rico. Just before the storm moved ashore, the government of Haiti issued a tropical storm warning for its northern coastline, and later a tropical storm warning was issued for the Turks and Caicos Islands, as well as the southeastern Bahamas.
