Due to the size of Isaac’s wind field and its forward motion, a hurricane warning has been posted for the Florida Keys, as well as coastal Collier, mainland Monroe, and far south Miami-Dade counties.
Hurricane watches are also posted for inland Miami-Dade, metro Miami-Dade and coastal Miami-Dade counties.

According to the National Hurricane Center, if peak storm surge occurs at high tide, peak water levels above ground could reach the following depths as Isaac moves by:
– Southwest Fla. coast: 5-7 feet
– Fla. west coast, including Tampa Bay: 3-5 feet
– Southeast Fla. coast, Fla. Keys: 1-3 feet
– Hispaniola, eastern Cuba: 1-3 feet
– Bahamas, Turks and Caicos: 1-3 feet
Bands of heavy rain triggered flooding in Puerto Rico through Friday, even as Isaac’s center remained well to the southwest. A bridge collapse and mudslide was reported early Friday. Power outages were also reported over parts of the commonwealth, as well as the U.S. Virgin Islands Thursday.
While Isaac’s center of circulation has passed west and northwest of Hispaniola, some heavy rainbands on the cyclone’s eastern flank could continue to impact Haiti and the Dominican Republic. Storm total rainfall of 8 to 12 inches is possible (locally 20 inches). Additionally, 4 to 8 inch storm-total rainfall, with isolated 12 inch amounts, are possible in Jamaica. Life-threatening flash floods and mudslides will likely result from that amount of rain.
Numerous watches and warnings have been issued for Florida, Cuba and the Bahamas.
