Tropical Storm Ernesto now in Caribbean

SAN JUAN, Puerto Rico — Tropical Storm Ernesto formed Friday over the Caribbean as it moved toward Jamaica and the Cayman Islands, the U.S. National Hurricane Center said. Ernesto, which posed no immediate threat to land, could develop next week into the first hurricane of the 2006 Atlantic season, the center said. The outer edges of the storm were expected to bring rain to Puerto Rico, the Dominican Republic, and Haiti over the next 24 hours.
