Dorian will remain a large and risky hurricane as the storm tracks northward near or just offshore the Florida east coast through Wednesday, Sept. 4, the National Hurricane Center said in a new advisory issued Tuesday morning.
Dorian's strongest winds remained offshore on Wednesday, but the center of the storm is forecast to get much closer to the coast in South and North Carolina starting on Thursday.
It has been more than 24 hours since Dorian made landfall on Grand Bahama Island and it has not moved in more than 15 hours, meaning the same communities across the Bahamas have been thrashed by the deadly storm.
In 2017, Hurricane Harvey got stuck when steering currents collapsed, absolutely drenching Houston, but that wasn't as powerful a storm as Dorian, Klotzbach said. The hurricane stalled over the area for more than a day before it moved northwest toward Florida. The Grand Bahama airport was under 2m of water. The shelter is able to handle category 4 strength hurricanes. That's a sharp decrease from Sunday, when the storm was a category 5 hurricane, packing sustained winds of up to 185 miles per hour.
The NHC is warning of potential storm surges of up to 8 feet in some areas of SC, and says that total rainfall could reach as high as 15 inches in some isolated areas of the coastal Carolinas. Four to eight inches are possible in the the Atlantic Coast and between the Florida Peninsula through Georgia, with isolated amounts of ten inches possible.
Although the fastest wind speeds have dropped, the storm's hurricane-force core has widened since hitting the Bahamas.
South Carolina Governor Henry McMaster ordered mandatory evacuations for parts of eight coastal counties effective at noon on Monday.
Multiple scenarios remain in play for this system - which has already prompted mass (premature?) evacuations along the SC coast.
Orlando International Airport, one of the largest in the state, planned to cease commercial operations at 2am on Tuesday because of the storm, it said in a statement. President Donald Trump has granted emergency declarations for Florida, South Carolina and Georgia, with the governors of North Carolina and Virginia also declaring a state of emergency.
