ISLAMORADA -- Florida has battened down the hatches for what could be the first hurricane strike in seven years. Schools were ordered closed. Republicans postponed the national convention in Tampa.
Tourists jammed U.S. 1 out of the Florida Keys. And local TV shifted to endless radar loops of a massive but messy storm called Isaac rolling up the Cuban coast.
At 5 a.m. Sunday, the path remained the same but the storm strengthened a little overnight. With the advisories, the National Hurricane Center made it clear: Isaac, which killed at least three people in Haiti, was going to hit somewhere in the Keys on Sunday, possibly as a 75- to 80-mph hurricane.
Tropical storm winds were expected to begin lashing the islands near dawn and steadily worsen, spreading north across Miami-Dade and Broward counties throughout the day. Four to eight inches of rain could flood already saturated neighborhoods, rough seas and storm surge could spill over roads and docks and there is a heightened risk of tornadoes.
Steve Willis, harbor master at Smugglers Cove Marina in Islamorada, shrugged the threat off early Saturday with characteristic Keys nonchalance. He planned to ride Isaac out on his 37-foot sailboat, while watching over 10 other boats from a 52-foot charter fishing boat to an 11-foot Zodiac docked at the marina.
They are hunkered down pretty good, and with the likely direction of the wind, the [Snake Creek] bridge, sand berms and mangroves will protect this marina, he said. But I am worried about Barnacle Bobs. He could be my problem child. Barnacle Bob is a floating burger shack, a light, high-sided pontoon boat Willis worried would get whipped around by the wind.
But emergency managers in South Florida were taking no chances on a storm with a wind field more than 200 miles wide. Monroe, Miami-Dade and Broward counties all ordered schools closed Monday, and private schools and universities followed the lead. All three counties also opened shelters and urged residents to stay indoors until the storm passes sometime Monday morning.
Florida Gov. Rick Scott issued a state of emergency, expressing concern about the damage Isaac might do once it passes the Keys and fuels up in the warm Gulf of Mexico. It was forecast to grow into a Category 2 Hurricane with 100 mph winds as it approaches the Panhandle on Tuesday.
Rick Knabb, director of the National Hurricane Center in West Miami-Dade, said that a strengthening Isaac in the Gulf could pose a storm surge threat to Tampa Bay, where the Republican National Convention was scheduled to convene Monday in an area vulnerable to flooding. Events will now be delayed until Tuesday afternoon.
In Miami-Dade, Mayor Carlos Gimenez also issued an evacuation order for people living in mobile homes, unsafe buildings and homes in low-lying, flood-prone areas. The Keys did the same, adding an order for boat dwellers to seek safer shelter.
Even though Broward is not under a hurricane warning, Browards director of emergency operations, Chuck Lanza, said Saturday that residents still need to be prepared for damaging tropical storm-force winds.
Im putting up my own shutters, he said. This is not something to take lightly.
Though Isaacs wind werent powerful, the huge storm still left a path of death and damage in the Caribbean.
In Haiti, a home collapsed, killing a 10-year-old girl while flooding persisted in quake-battered Port-au-Prince, where the swollen Grise River inundated homes in the poverty-stricken Cite Soleil neighborhood. At least two other deaths were reported and rain was still falling much of Saturday across a country prone to deadly flash floods and mudslides.
Havanas Meteorological Institute reported that the storm touched down in Maisi, a municipality east of Guantanamo Saturday afternoon. Radio Baracoa reported that two homes in the islands easternmost city of 48,000 had collapsed.
But the storms drama fizzled at the U.S. Navy base at Guantánamo Bay, Cuba, where the military had scrapped this months Sept. 11 terror trial hearings.
The bad weather did not materialize here, detention center spokesman Robert Durand said.
Forecasters believe the systems jaunt over Cuba will be brief and allow the storm more time to strengthen in the warm waters of the Florida Straits. Isaacs impact depended on how quickly and well the sloppy storm ramped up as it crossed the Florida Straits, with NHC director Knabb saying there was not a 100 percent guarantee it would reach Category 1 strength by the time it hits the Keys.
But the chances were good it could become the first hurricane to make landfall in South Florida since Category 3 Wilma in 2005. Isaac wont produce anywhere near the damage, but Miami-Dade and Broward will be on the storms dirty side with the strongest winds. Forecasters predicted the sprawling storm could produce from six to 10 inches of rain and powerful gusts.
In the Keys, which will feel the worst weather, shelters opened, police urged tourists to evacuate and the citys airport closed.
Frank Gambino, of a Marathon pool service company, is concerned about flooding, especially after 2005 storm flooding reached nine feet.
Im making sure I get everything off the floor in case we get some localized flooding, Gambino said. We dont plan on working until Tuesday at least. But it all depends on the severity of the storm.
Down U.S. 1, Forest Tek Lumber also was busy, but plywood wasnt flying off the shelves. Most residents in the Keys already have storm shutters or high-impact windows and glass.
Of course, others made the most of the impending storm.
At Key Wests Southernmost Point buoy monument, where television news reporters took turns doing stand-up reports, Chenco Leon took photos of his girlfriend, Jorie Rogers, who was topless save for a Conch Republic flag wrapped around her body.
The two, who moved to the island recently from Indiana, are working on a Key West calendar featuring distinctive pictures of the Island City.
We prepared. We have canned goods. We took the car to the highest point, over by the cemetery. Im not too worried. All the locals said its a Category 1. Back home we live with tornadoes all the time, so its not a big deal here, Leon said.
