Isaac Heading Our Way After Drenching Caribbean

KEY WEST (CBSMiami/AP) — Tropical Storm Isaac is heading toward South Florida and the Keys after swamping the Caribbean and forcing plans to be shuffled for the Republican National Convention.

A steady line of cars moved north along the Overseas Highway Saturday evening while residents boarded up windows, laid down sandbags and shuttered businesses ahead of the approaching storm. Even Duval Street, Key West's storied main drag, was subdued for a weekend, though not enough to stop music from playing or drinks from being poured.

"We'll just catch every place that's open," said Ted Lamarche, a 48-year-old pizzeria owner visiting Key West to celebrate his anniversary with his wife, Deanna. They walked along on Duval Street, where a smattering of people still wandered even as many storefronts were boarded up and tourists sported ponchos and yellow slickers.

"Category None!" one man shouted in a show of optimism.

Isaac was expected to be at or near hurricane strength by the time its center reached the Keys later Sunday. A hurricane warning was in effect for the Keys and authorities warned tourists to head for the mainland. Meanwhile authorities said a hurricane watch has been issued from the mouth of the Mississippi River — not including the New Orleans metro area — eastward to Indian Pass., Fla.

When it hits, winds will be "enough to knock you over," National Hurricane Center spokesman Dennis Feltgen said.

The Keys were bracing storm surge of up to four feet, strong winds and the possibility of tornadoes. The island chain's two airports closed Saturday night and volunteers and some residents began filing into shelters.

"This is a huge inconvenience," said Dale Shelton, a 57-year-old retiree in Key West who was staying in a shelter.

The hurricane center said the storm, which was swirling off the northern coast of Cuba overnight, was expected to move near or over the Florida Keys later in the day or Sunday night. Isaac was then forecast to move over the southeast Gulf of Mexico on Monday.

Forecasters said some more strengthening was expected over the next 48 hours with Isaac set to be at or near hurricane strength upon reaching the Keys.

Among the highest-profile potential targets of the storm was the Republican National Convention, set to begin Monday in Tampa. Forecast models show Isaac likely won't hit Tampa head-on, but it could have lashed the city with rain and strong winds just as the convention was ramping up. A tropical storm warning was extended north of Tampa Bay.

Convention officials said they would convene the convention briefly on Monday, then immediately recess until Tuesday afternoon, when the storm should have passed. Florida Gov. Rick Scott, a Republican, declared a state of emergency and canceled his plans to attend convention events on Sunday and Monday.

Isaac has already left a trail of suffering across the Caribbean.

The storm's center made landfall Saturday near the far-eastern tip of Cuba, downing trees and power lines. In the picturesque city of Baracoa, the storm surge flooded the seaside Malecon and a block inland, destroying two homes.

At least four people were reported dead in Haiti, including a 10-year-old girl who had a wall fall on her, according to the country's Civil Protection Office. The government also reported "considerable damage" to agriculture and homes. Nearly 8,000 people were evacuated from their houses or quake shelters and more than 4,000 were taken to temporary shelters.

The Grise River in Haiti overflowed north of Port-au-Prince, sending chocolate-brown water spilling through the sprawling shantytown of Cite Soleil, where many people grabbed what possessions they could and carried them on their heads, wading through waist-deep water.

"From last night, we're in misery," said Cite Soleil resident Jean-Gymar Joseph. "All our children are sleeping in the mud, in the rain."

Scores of tents in quake settlements collapsed. In a roadside lot in Cite Soleil, the dozens of tents and shelters provided by international groups after the earthquake were tossed to the ground like pieces of crumpled paper, and the occupants tried to save their belongings.

"They promised they were going to build us a sturdy home and it never came," Jean-Robert Sauviren, an unemployed 63-year-old father of six said as he stood barefoot in the water and held aloft his arms. "Maybe we don't deserve anything."
