MIAMI (Reuters) - Tropical Storm Ernesto kept on a westerly course in the Caribbean Sea on Saturday and will soon bulk up into a hurricane that may soak Jamaica as it passes by the island, U.S. forecasters said.
Officials in Jamaica issued a tropical storm warning as Ernesto moved in open waters at 18 miles per hour on a predicted track that should keep it at sea until a forecast landfall in Mexico's Yucatan Peninsula on Wednesday.
