Georgia is preparing for coastal evacuations as Hurricane Dorian approaches the southeastern United States.

State officials held a press conference Wednesday evening, hours after Dorian reached hurricane strength and passed by the U.S. Virgin Islands and Puerto Rico.

Georgia Gov. Brian Kemp stressed that it is "very difficult" to project just where the storm may head in the coming days, and therefore, his administration is preparing for a number of possibilities. "We are already weighing considerations on how to potentially handle evacuation scenarios, including evacuations out of Florida into Georgia inland from Georgia's coast and what that may mean for traffic on our roadways throughout the Southeast," he said.

Kemp said discussions on how to deal with "vulnerable populations," including elderly, hospital populations, homeless people, and inmates. He also said preparations include communicating with the federal government and neighboring states.

The National Hurricane Center is expecting a "major" Category 3 hurricane to make landfall over the Florida Peninsula over Labor Day weekend. Beyond that, forecasters caution that there is a great deal of uncertainty about where the storm will head.

Some models show Dorian sweeping across Florida and into the Gulf Coast. Others have it turning north after it hits Florida.

Authorities will set up an Emergency Operations Center at noon on Thursday, Homer Bryson, director of the Georgia Emergency Management and Homeland Security Agency, said at the press conference.

Florida Gov. Ron DeSantis declared a state of emergency for more than two dozen eastern Florida counties earlier in the day and urged residents to stock up on supplies for the next seven days. Evacuations in the Sunshine State will happen as Dorian gets closer and landfall becomes more certain, but DeSantis has not yet any.

Kemp said he is not going to make a emergency declaration just yet, noting that he hopes to have a "clearer picture of Dorian's trajectory" within the next 24 hours.
