While the storm weakened, hurricane warnings remain in place for more than four million people.
Across three states, more than 12 million people are under a tropical storm warning.
The storm was southwest of Tampa early Wednesday morning, where residents were urged to stay indoors.
As the storm churns off the western coast of Florida with maximum sustained winds of 70 mph, it is expected to be near the Pinellas Peninsula around 2 a.m. EST – the closest it will be to land before it makes landfall later in the morning.
The system is moving north at 14 mph on a collision course with Cedar Key in the Big Bend area, where it is expected to make landfall late Wednesday morning.
Florida Gov. Ron DeSantis expanded his state of emergency declaration Tuesday to include a total of 33 counties as local, state and utility resources continue to prepare for the incoming storm.
The Florida National Guard has activated 60 guardsmen to serve at the State Emergency Operations Center and Logistics Readiness Center, according to a release from the Guard. It is prepared to activate additional personnel as needed.
“We are well-equipped with assets including high-wheeled vehicles, helicopters, boats and generators, and are preparing for possible missions to include humanitarian assistance, security operations, search and rescue, aviation, and more,” the guard said in the release.
In Tampa, officials urged residents to stay off the roads as the storm approaches.
Counties and utilities preparing ahead of storm
Both the mayor and emergency coordinator for the city of Tampa posted on social media Tuesday to encourage residents to stay home and be prepared.
“We want everybody to be safe in Tampa and we’ll be up all night monitoring the storm so you don’t have to,” she added.
Earlier, Tampa Emergency Coordinator John Antapasis said it was time for residents to get to safety ahead of the expected landfall.
“Now is the time to get back home, get off the streets and stay safe for the rest of tonight,” he said. “You should be making and finalizing your hurricane plans and ensuring that you’re in a safe location while … Elsa makes it’s way through out community.”
Antapasis advised that people who need to be on the road should check the city’s flood map.
Manatee County Administrator Scott Hopes also warned people to get ready for the storm during a press conference Tuesday.
“Please finalize your plans and secure your homes and get ready to sort of bunker down and ride out this storm,” Hopes said.
Shelters were opened in at least five counties Tuesday and two counties issued voluntary evacuation orders.
Additional line workers and support personnel have also been brought in from the Carolinas, Indiana, Kentucky, and Ohio, according to the release.
Tropical storm warnings and emergency declarations extended
Ahead of Elsa’s landfall in Florida, tropical storm warnings have been issued in Georgia and the Carolinas.
The warnings extend northward from the Altamaha Sound, just north of Brunswick, Georgia, towards the Little River Inlet, on the state border between the Carolinas.
A tropical storm watch has been issued north of the Little River Inlet to Duck, North Carolina, on the Outer Banks. This watch includes the Pamlico and Albemarle sounds of the North Carolina lowlands.
On Tuesday, Georgia Governor Brian Kemp issued a State of Emergency in preparation for the impact of Elsa.
“This storm system has the potential to produce destructive impacts to citizens throughout the central, southern, and coastal regions of the State of Georgia and due to the possibility of downed trees, power lines, and debris, Georgia’s network of roads may be rendered impassable in the affected counties, isolating residences and persons from access to essential public services,” Kemp said.
A State of Emergency has been declared in 91 of Georgia’s 159 counties, according to Kemp’s order. The order will expire Wednesday at midnight unless the governor decides to renew it.
