The official forecast calls for Isaac to become a hurricane by Friday morning, but perhaps the more ominous threat in the short term is the potential for extremely heavy rainfall over the islands near Isaac’s path.
Over a foot of rainfall, and potentially as much as 20 inches in a few locales, is possible on the island of Hispaniola, home to Haiti and the Dominican Republic. Life-threatening flash floods and mudslides would likely result from that amount of rain.
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 few days.
