Before reaching Florida, Isaac was blamed for seven deaths in Haiti and two more in the Dominican Republic, and downed trees and power lines in Cuba. It bore down on the Keys two days after the 20th anniversary of Hurricane Andrew, which caused more than $25 billion in damage just north of the island chain.
In Tampa, convention officials said they would convene briefly today, then recess until tomorrow afternoon, when the storm was expected to have passed. Gov. Rick Scott canceled his plans to attend convention events yesterday and today.
At Miami International Airport, more than 450 flights yesterday were canceled. Inside the American Airlines terminal, people craned for a look out of one of the doors as a particularly strong band of Isaac began lashing the airport with strong rain and high wind.
Michele Remillard said she was trying to get a seat on a flight to New Orleans, well aware the city could be affected by Isaac later this week. In coastal Plaquemines Parish, La., crews rushed to protect the levees that keep floodwaters from reaching that New Orleans suburb.
"It's a little scary," said Remillard, who was in town for a wedding. "But I need to get home, you know? And if the storm comes my way again, who knows, I might have to come back here."
