(CNN) Tropical Storm Elsa, which brought heavy rain and high winds to parts of Florida and Georgia, moved into the Carolinas on Thursday and is forecast to race northward up the East Coast over the next few days.
Tornadoes were reported across northern Florida and southeastern Georgia on Wednesday, including an EF-2 tornado that caused multiple injuries and damage at Naval Submarine Base Kings Bay in Kings Bay, Georgia.
"Thankfully, there was no loss of life here last night. This tornado that came through could have been a lot worse," base commanding officer Capt. Chester Parks told CNN affiliate WJXT.
Parks said a tornado impacted the south side of the base and moved north through the base RV park. Twelve recreational vehicles were damaged and nine people were transported off the base for treatment, he said.
As of 8 p.m. Thursday, Elsa was located about 65 miles west of Norfolk, Virginia, with maximum sustained winds of 50 mph. The storm is moving at a brisk pace of 21 mph to the northeast, according to the National Hurricane Center.
In parts of South Carolina, the NHC estimated rainfall totals of 3 to 5 inches with isolated maximum totals of 8 inches through Thursday, which could cause limited flash and urban flooding. Tornadoes are possible across the eastern Carolinas into southeast Virginia through Thursday afternoon, the NHC said.
North Carolina emergency officials advised residents to prepare for possible outages and avoid driving through floodwaters.
"The storm's impacts can vary by location," North Carolina Emergency Management chief of staff Will Ray said in a statement. "Heavy rain, gusty winds, flooding, (tornadoes) and power outages are all possible with this storm, so please pay close attention to the forecast for your area."
The Coast Guard's 5th District Mid-Atlantic base in Portsmouth, Virginia, issued warnings Thursday ahead of Elsa.
"Mariners, boaters, and beachgoers alike should stay safe, alert and follow advisories as harsh weather, seas, and winds impact their area," the Coast Guard said in the release.
Elsa is expected to maintain tropical storm strength as it moves into the Mid-Atlantic states and toward the northeast US. Tropical storm warnings are in place from North Carolina to New England. The 700-mile swath covers an area home to 27 million people.
Other parts of the East Coast could see 2 to 4 inches of rain through Friday as well. Due to the heavy rainfall, more than 50 million people are under flash flood watches from the Carolinas to Maine, including Baltimore, Philadelphia, New York and Boston.
Elsa's first US target was Florida -- and it caused damage and one death near the Georgia-Florida border.
Elsa made landfall late Wednesday morning along the Gulf Coast in Taylor County, Florida, the NHC said. Roads flooded in Steinhatchee, CNN affiliate WCTV reported.
In Jacksonville, winds from Elsa caused a tree to fall on two cars during an afternoon commute, killing one person, according to Capt. Eric Prosswimmer with the Jacksonville Fire and Rescue Department. A possible tornado touched down in the city Wednesday evening, according to Mayor Lenny Curry.
In Cedar Key, part of a roof's surface had been lifted from a motel, photos taken by motel guest Jonathan Riches showed.
"Winds starting howling in the middle of the night, and rain starting pounding the windows," Riches told CNN, adding about the conditions: "Never seen anything like this before in my life."
Overall, Gov. Ron DeSantis said, Elsa left "minimal impact" across the state.
"As these things go, probably as minimal impact as we would have anticipated if we went back four or five days. There was not any widespread property damage," he said during a Thursday news conference in Surfside.
DeSantis also addressed the one death in the state. "We're obviously very, very sad to see that," he said.
