UPDATE: Sept. 4, 2019: Hurricane Dorian continued to move very slowly northwest into Wednesday morning, still threatening much of the southeastern U.S. The storm is now expected to get "dangerously close" to Florida's east coast and Georgia Wednesday and move toward the coast of South Carolina and North Carolina Thursday through Friday morning. The Ports of Miami and the Everglades reopened Wednesday. Virginia Governor Ralph Northam declared a state of emergency for his state Tuesday, but the Port of Virginia remains open. Norfolk Southern has closed intermodal origin facility gates destined for Savannah, Charleston, and Florida east coast destinations across its system. 

Dive Brief:

• Hurricane Dorian is inching its way northwest at about 1 mph, according to the National Hurricane Center (NHC), threatening the U.S. southeast coast after pummeling the Bahamas over the weekend. The storm will get "dangerously close to the Florida east coast late Tuesday through Wednesday evening, very near the Georgia and South Carolina coasts Wednesday night and Thursday, and near or over the North Carolina coast late Thursday," according to an NHC notice Tuesday morning. Five people have already died as a result of the storm in the Bahamas, according to media reports.

The Georgia Ports of Savannah and New Brunswick will be closed Tuesday and Wednesday, according to the Georgia Port Authority. Marine terminals at the Ports of Charleston and Georgetown South Carolina will be closed Wednesday and Thursday and reopen Friday, according to an announcement from the Port Authority. The Ports of Wilmington and Morehead City in North Carolina will operate normal gate hours Tuesday and close at noon on Wednesday. Neither port is receiving refrigerated cargo for export as of Tuesday.
• Norfolk Southern is staging repair equipment to expedite repairs should they be necessary and CSX is warning customers to expect delays in affected areas.

Dive Insight:

After pummeling the Bahamas and causing unprecedented damage, Dorian will shut down most ports in the Southeastern U.S. by Wednesday, though it's still unclear where and if the storm will make landfall in the U.S. at all.

Based on Tuesday morning forecasts, the Florida coast is out of the "cone of uncertainty," or the path the storm is currently expected to take. However, this storm has proven to be unpredictable and authorities are still urging Floridians to heed warnings and instructions.

The Federal Motor Carrier Safety Administration expanded its Hours of Service regulations suspension to Alabama, Florida, Georgia, Kentucky, Lousiana, Missouri, North Carolina, South Carolina, Tennessee, Virginia, Puerto Rico and the U.S. Virgin Islands last week and gas trucks in Florida are receiving police escorts in order to to keep fuel flowing and freight moving.

Some highway authorities are reversing lanes to better accommodate traffic leaving affected areas and several airports in the area have closed to ride out the storm.

Though there are some conflicting reports on Twitter, Freeport Container Port (FCP) in Grand Bahama, which took years to recover full function after Hurricane Matthew in 2016, according to Lloyd's List, has not lost any cranes in the storm. Though the island sustained serious damage, the deep-water port may be in relatively good condition, which could be important to receiving supplies for the recovery effort.
