Tropical Storm Isaac is forecast to continue strengthening steadily as it moves through the northern Lesser Antilles on Wednesday and into the northeast Caribbean by Thursday. Isaac could become a hurricane as early as Thursday.
Residents and visitors of the northern Caribbean, Yucatan Peninsula, southeastern United States and the central/eastern Gulf Coast should watch the progress of Isaac closely over the next week or more.
Initial impacts from Isaac will be felt in the northeastern Caribbean islands Wednesday into Thursday. Numerous watches and warnings have been issued, including a hurricane watch for Puerto Rico, the U.S. Virgin Islands and the southern Dominican Republic. Puerto Rico will see its greatest impacts from Isaac on Thursday.
Friday into the weekend, Isaac is forecast to pass near or south of Hispaniola and in the general direction of eastern Cuba.
Heavy rainfall, flooding and mudslides will be threats in all of the northern Caribbean islands regardless of how strong the system becomes.
