Hurricane Sandy is continuing to weaken as it makes its way north after lashing the Bahamas late Thursday.
The 5 a.m. advisory says the hurricane has maximum sustained winds of 80 mph and is moving NW at 13 mph. The hurricane's center was 15 miles east-southeast of Great Abaco Island and about 485 miles south-southeast of Charleston, SC.
Hurricane Sandy caused at least 21 deaths and forced postponement of a hearing at the Guantanamo naval base in Cuba. Eleven of those deaths occurred in Cuba.
By late Thursday, Sandy had slowed to a category 1 hurricane, and as of Friday morning, it has continued to slow down. Forecasters say it is expected to weaken a little throughout Friday, but it should remain a hurricane for the next few days as it heads north.
Forecasters are also warning that it will likely blend with a winter storm to cause a super storm in the eastern U.S. next week whose effects will be felt along the entire Atlantic Coast and inland to Ohio.
A Tropical Storm Warning remains in effect for South Florida. Forecasters said tropical storm conditions were possible along the southeastern Florida coast, the Upper Keys and Florida Bay by Friday morning.
Caroline Turnquest, head of the Red Cross in the Bahamas archipelago off Florida's east coast, said 20 shelters were opened on the main island of New Providence.
"Generally people are realizing it is serious," she said.

On Marsh Harbour, power was out island-wide Thursday night. Timothy Roberts, a resident and journalist with the Abacoan, reported winds sustained up to 50 miles per hour and gusts over 60 miles per hour.
All business were closed on the island with the exception of a gas station.
"Basically, everyone is hunkered down and waiting it out," Roberts said.
Power was out on Acklins Island and most roads there were flooded, government administrator Berkeley Williams said. He said his biggest concern was that a boat filled with basic supplies for the island had to cancel its trip until next week.
"Supplies were low before, so you can imagine what we are going through now," Williams said.
On Ragged Island in the southern Bahamas, the lone school was flooded. "We have holes in roofs, lost shingles and power lines are down," said Charlene Bain, local Red Cross president. "But nobody lost a life, that's the important thing."
Steven Russell, an emergency management official in Nassau, said that docks on the western side of Great Inagua island had been destroyed and that the roof of a government building was partially ripped off.
"As the storm passes over Eleuthera and Cat Island, they should get a pretty good beating," he said. "There are sections of Eleuthera we are concerned about."
The huge Atlantis resort went into lockdown after dozens of tourists left Paradise Island before the airport closed, said George Markantonis, president of Kerzner International, which manages the resort. He said the resort was now less than half full, but all its restaurants, casinos and other facilities were still operating.
Sooner Halvorson, a 36-year-old hotel owner from Colorado who recently moved to the Bahamas, said she and her husband, Matt, expected to ride out the storm with their two young children, three cats, two dogs and a goat at their Cat Island resort.
"We brought all of our animals inside," she said, though she added that a horse stayed outside. "She's a 40-year-old horse from the island. She's been through tons of hurricanes."
On Great Exuma island, guest house operator Veronica Marshall supplied her only customer with a flashlight and some food before Sandy bore down. The storm-hardened Bahamian said she was confident that she and her business would make it through intact.
"I'm 73 years old and I've weathered many storms," she said.
With storm conditions projected to hit New Jersey with tropical storm-force winds Tuesday, there is a 90 percent chance that most of the U.S. East Coast will get steady gale-force winds, flooding, heavy rain and maybe snow starting Sunday and stretching past Wednesday, U.S. forecaster Jim Cisco said.
State media in Cuba said Sandy toppled houses, ripped off roofs and killed 11 people in the eastern provinces of Santiago and Guantanamo as it roared over the island as a category 2 storm early Thursday. Nine deaths were reported in Haiti and one in Jamaica.
Cuban authorities said the 11 dead included a 4-month-old boy who was crushed when his home collapsed and an 84-year-old man in Santiago province.
It was Cuba's deadliest storm since July 2005, when Hurricane Dennis slammed into the island as a category 5 storm, killing 16 people and causing an estimated $2.4 billion in damage.
Santiago, Cuba's second largest city near the eastern tip of the island, was spared the worst of Sandy which also slammed the provinces of Granma, Holguin and Las Tunas.
Cuban President Raul Castro ordered authorities to evaluate damage throughout eastern Cuba.
There were no reports of injuries at the U.S. naval base at Guantanamo Bay in Cuba, but there were downed trees and power lines, said Kelly Wirfel, a base spokeswoman. Officials canceled a military tribunal session scheduled for Thursday for the prisoner charged in the 2000 attack on the Navy destroyer USS Cole.
In Haiti, Joseph Edgard Celestin, a spokesman for the civil protection office, said the country's death toll stood at nine, including three people who died while trying to cross storm-swollen rivers in southwestern Haiti. He did not provide specifics of how other people died.
Officials reported flooding across Haiti, where many of the 370,000 people still displaced by the devastating 2010 earthquake scrambled for shelter. More than 1,000 people were evacuated from 11 quake settlements, according to the International Organization for Migration.
Sandy was blamed for the death of an elderly man in Jamaica who was killed when a boulder crashed into his clapboard house, police said.
