Although Dorian wasn't forecasted to make landfall, the NHC noted that the wind field increased and any deviation of the track to the east would wring hurricane-force winds onshore along portions of Florida's east coast. "The hurricane hit on October 10th along the Florida Panhandle as a category 4 storm causing massive damage and claimed the lives of more than a dozen people".
The hurricane agency said that with its expected path, Dorian would track "dangerously close" to the Florida coast on Tuesday night, advancing northward very near the Georgia and SC coasts by Wednesday night and Thursday, and the North Carolina coast by late Thursday. Choppy brown floodwaters reached roofs and the tops of palm trees.
At least five deaths have been blamed on the storm.
As the hurricane moved north Tuesday, large swaths of the islands remained under water, and the true death count is still unknown.
"We will be closing Universal Studios Florida and Universal's Islands of Adventure as of 6 PM today", a spokesperson for the Comcast-owned theme park said Tuesday. The hurricane's fearsome power tore off roofs and sent cars tumbling, while Dorian's heavy rain flooded the entire first floor of many homes.
The National Hurricane centre said Dorian is expected to move "dangerously close" to the Florida east coast late Tuesday through Wednesday evening and then move north to coastal Georgia and SC on Wednesday night and Thursday.
The storm, one of the most powerful Atlantic hurricanes on record, was stalled over Grand Bahama Island, packing maximum sustained winds of 249 kilometres per hour and moving at 2 kph, the Miami-based National Hurricane Centre (NHC) said in an advisory at 11:00am (local time).
A state of emergency has been declared up and down the coast for millions of USA coastal residents in the path of the monster storm.
Across the Southeast, meanwhile, interstate highways leading away from the beach in SC and Georgia were turned into one-way evacuation routes.
Abaco and Grand Bahama islands, with a combined population of about 70,000, are known for their marinas, golf courses and all-inclusive resorts.
"As it gets closer and closer to the Florida coastline, it means we'll feel more and more of the winds". It remained almost stationary 25 miles northeast of Freeport, Bahamas and 105 miles east of West Palm Beach, Florida - the same position it was in at 9 a.m. Monday.
Authorities in Florida also ordered some mandatory evacuations.
In South Carolina, Interstate 26 was turned into a one-way evacuation route away from Charleston on the coast, and Georgia Gov. Brian Kemp likewise planned to reverse lanes on I-16 on Tuesday to speed the flow of traffic away from the danger zone.
The Coast Guard said helicopter crews medevaced 19 people from the Marsh Harbour Clinic to the Nassau International Airport on Monday.
He added that the sea surge from the storm was high and people were still trapped in their homes and attics.
"We will confirm what the real situation is on the ground", Health Minister Duane Sands said.
