She and her husband did not board up their home as they did ahead of last September’s Hurricane Ian, saying they are more concerned about flooding than high winds this time.
“We’re on the canal and just 9 feet (3 metres) above sea level,” she said.
The NHC said Idalia’s centre would likely hit Florida’s coastline somewhere in the Big Bend region, where the state’s northern panhandle curves around into the Gulf side of the Florida Peninsula. The area, roughly between the inland cities of Tallahassee and Gainesville, is much more lightly populated than the Tampa-St. Petersburg area to the south.
Most of Florida’s 21 million residents, along with many in Georgia and South Carolina, were under hurricane, tropical storm and storm surge warnings and advisories.
A state of emergency was declared for South Carolina on Tuesday by Governor Henry McMaster to spur preparations for the tempest. DeSantis issued a similar proclamation for Florida earlier this week.
Idalia grew from a tropical storm into a hurricane early on Tuesday, a day after passing west of Cuba, where it damaged homes and flooded villages.
By early Tuesday afternoon, the storm was churning about 390 km southwest of Tampa as it crept northward.
Idalia is in line to become the fourth major hurricane to strike Florida over the past seven years, following Irma in 2017, Michael in 2018 and Ian, which peaked at Category 5, last September.
In Sarasota – a city hard-hit by Ian last year – Milton Bontrager’s home is boarded up and stocked with food, water and a generator.
“I don’t panic, I prepare,” said Bontrager, 40, who runs six sport and charter fishing boats in Venice along the Gulf Coast near Tampa.
He stopped taking customers out days ago so he could secure the boats. His biggest craft is tied down to a floating dock with 16 lines and equipped with battery-powered pumps that turn on automatically if the boat starts taking on water.
Florida’s Gulf Coast along with southeastern Georgia and eastern portions of North and South Carolina could face torrential rains of 10 to 20 cm through Thursday, with isolated areas seeing as much as 30 cm, the hurricane centre warned.
Surge warnings were posted for hundreds of miles of shoreline, from Sarasota to the sport fishing haven of Indian Pass at the western end of Apalachicola Bay. In some areas, the surge of water could rise 3.0 to 4.6 metres, the hurricane centre said.
“The No. 1 killer in all of these storms is water,” Deanne Criswell, the Federal Emergency Management Agency’s administrator, said on CNN.
More than 40 school districts across the region cancelled classes, DeSantis said. Tampa International Airport planned to suspend commercial operations beginning at midday Tuesday.
Some 5500 National Guard troops were mobilised and between 30,000 and 40,000 electricity workers were placed on standby. The state has set aside 1.1 million gallons of gasoline to address any interruptions to fuel supplies, DeSantis said.
As Floridians braced for Idalia’s arrival, Cubans were grappling with the aftermath of the storm, which lingered for hours on Monday near the western end of the Caribbean island nation, toppling trees and flooding coastal villages.
On Monday, brown floodwaters swamped the small fishing village of Guan, an hour’s drive south of Havana.
Decades-old buses missing floorboards and windows carried women and children to higher ground as winds howled, rattling tin roofs and slamming fishing boats tucked in the mangroves.
In Pinar del Rio, an area known for producing the tobacco used to make some of the world’s finest cigars, 60 per cent of the province was without power.
Authorities evacuated tens of thousands of people from that province as well as neighbouring Artemisa, while squalls of heavy rain doused the Cuban capital of Havana.
