Tropical Storm Isaac strengthened slightly as it spun toward the Dominican Republic and Haiti, but seemed unlikely to gain enough steam early yesterday to strike the island of Hispaniola as a hurricane.
The storm’s failure to gain the kind of strength in the Caribbean that forecasters initially projected made it more likely that Isaac will not become a hurricane until it enters the Gulf of Mexico, said Eric Blake, a forecaster with the US National Hurricane Center in Miami.
“We think it could become a hurricane on Monday,” Blake said late on Thursday. “It would be somewhere over the Gulf of Mexico.”
The latest five-day forecast showed the storm’s path shifting to the west, possibly making landfall near the Alabama-Mississippi border, Blake said, but he added it was “too early to know” the exact course and stressed that Florida’s Gulf Coast, including Tampa, the site of next week’s Republican National Convention, was still in the forecast cone. The storm dumped heavy rain on Thursday across eastern and southern Puerto Rico and whipped up waves as high as 3m in the Caribbean as it churned across the region.
Late on Thursdsay night, Isaac was centered about 235km south-southeast of Santo Domingo, capital of the Dominican Republic, and had maximum sustained winds of 75kph. It was moving west-northwest at 30kph, according to the hurricane center.
In flood-prone Haiti, Prime Minister Laurent Lamothe urged people to avoid crossing rivers, to tape their windows and to stay calm, saying: “Panic creates more problems.”
Lamothe and other Haitian officials said the government had set aside about US$50,000 in emergency funds and had buses and 32 boats on standby for evacuations. However, among many Haitians, the notion of disaster preparedness in a country where most people get by on about US$2 a day was met with a shrug.
“We don’t have houses that can bear a hurricane,” said Jeanette Lauredan, who lives in a tent camp in the crowded Delmas district of Port-au-Prince.
About 400,000 people remain in settlement camps comprised of shacks and tarps in the wake of Haiti’s devastating 2010 earthquake.
So far, Isaac itself had caused no reported injuries or deaths, but police in Puerto Rico said a 75-year-old woman died near the capital of San Juan on Wednesday when she fell off a balcony while filling a drum with water in preparation for the storm.
In the Dominican Republic, authorities began to evacuate people from low-lying areas, but encountered resistance.
“Nobody wants to leave their homes for fear they’ll get robbed,” said Francisco Mateo, a community leader in the impoverished La Cienaga neighborhood in Santo Domingo.
The Dominican government planned to close all of the country’s nine airports by dawn on Friday, said Alejandro Herrera, civil aviation director. Schools were closed on Thursday afternoon.
The storm’s approach prompted military authorities at the US base in Guantanamo Bay, Cuba, to cancel pretrial hearings for five prisoners charged in the Sept. 11, 2001, attacks. They also evacuated about 200 people, including legal teams and relatives of Sept. 11 victims.
Blake, the US forecasts, said that while Isaac had not strengthened much in the Caribbean, it could gain power as it moves away from Cuba.
“When it moves back over water, it has a chance to restrengthen,” he said.
