(CNN) — Jamaicans and Haitians braced for Hurricane Matthew as the powerful Category 4 storm slowed to a crawl in the Caribbean on Saturday night, forecasters said.
While packing maximum sustained winds of 150 mph, the storm was “barely moving” at 8 p.m. ET Saturday, the National Hurricane Center reported. But a slow, northwestward motion is expected to begin later in the night, the center said.
The storm is expected to smack Jamaica and Haiti on Monday, but residents should be feeling its effects by Sunday.
Matthew may slam Cuba, the Bahamas and South Florida later next week, forecasters said.
Residents in South Florida have “the luxury of time,” said Rick Knabb, director of the National Hurricane Center in Miami. But he urged people to use it to prepare and buy supplies.
Weather models currently have Matthew possibly scraping the southern part of the state, but the hurricane center said Saturday afternoon that models are uncertain beyond the next three days.
“Therefore, it is too soon to rule out possible hurricane impacts from Matthew in Florida,” the agency said on Twitter.
Desmond McKenzie, a local government minister in Jamaica, called the storm a “national crisis”, according to a report in the Gleaner newspaper.
Storm shelters are open, agencies are ready to support evacuations, street people are being taken to shelters, utilities are preparing to deal with outages and fishermen have been asked to remain in safe harbor, the Gleaner reported.
Saturday afternoon, a hurricane watch was upgraded to a hurricane warning for Jamaica, which expects its first major hurricane since Gilbert in 1988.
Ivan Shaw, a videographer based in Kingston, said stores were open Saturday for last-minute shoppers. Some residents who live near the beach have evacuated, he said.
Marcia Forbes, a business owner in Kingston, told CNN she was preparing for a rough couple of days.
She waited in line to fill her car with gasoline, brought in her potted plants and filled her bathtub with water in case service is interrupted during the storm. She also placed sandbags against the shutters of her multimedia company and covered her office computers with plastic.
“Having lived through Hurricane Gilbert in 1988, I know what a Category 3 hurricane can do, (much) less a Category 4 or 5,” she told CNN. “Everyone in my community is taking this hurricane seriously and getting their homes shuttered up.”
In Haiti, a hurricane warning was issued Saturday afternoon from the southern border with the Dominican Republic to Le Mole St. Nicolas.
The Meteorological Service of Cuba issued a hurricane watch for eastern Cuba from the province of Camaguey southeastward to the province of Guantanamo.
The US Naval Station at Guantanamo Bay is evacuating about 700 spouses and children to Pensacola, Florida, and moving C-12 aircraft to Jacksonville, Florida,
Naval Station public information officer Julie Ann Ripley told CNN. Coast Guard personnel will be evacuated to Miami. There are no plans to evacuate any prisoners being held there.
The National Hurricane Center predicts life-threatening flash flooding and mudslides. Southern Haiti may receive 15-25 inches of rain and isolated parts of Haiti may receive as much as 40 inches, the center said.
