Hurricane Idalia strengthens to dangerous Category 4 storm

Hurricane Idalia strengthened to a dangerous Category 4 storm today as it steams toward Florida’s Big Bend region and threatens to unleash life-threatening storm surges and rainfall.

Idalia was projected to come ashore earlier as a Category 4 storm with sustained winds of at least 209km/h in the lightly populated Big Bend region, where the Florida Panhandle curves into the peninsula. The result could be a big blow to a state still dealing with lingering damage from last year’s Hurricane Ian.

The National Weather Service in Tallahassee called Idalia “an unprecedented event” since no major hurricanes on record have ever passed through the bay abutting the Big Bend.

Hurricanes are measured on a five category scale, with a Category 5 being the strongest. A Category 3 storm is the first on the scale considered a major hurricane. The National Hurricane Center says “catastrophic damage will occur” during a Category 4 storm.

At 9pm NZT, Idalia was about 96.5km west of Cedar Key and 145km south of Tallahassee, the National Hurricane Center said. It was moving north at 24 km/h.

Florida residents living in vulnerable coastal areas were ordered to pack up and leave as the hurricane gained strength in the warm waters of the Gulf of Mexico and authorities warned of a “catastrophic storm surge and destructive winds” when the storm moves ashore today.

On the island of Cedar Key, Commissioner Sue Colson joined other city officials in packing up documents and electronics at City Hall yesterday. She had a message for the almost 900 residents who were under mandatory orders to evacuate. More than a dozen state troopers went door to door warning residents that storm surge could rise as high as 4.5m.

“One word: Leave,” Colson said. “It’s not something to discuss.”

Governor Ron DeSantis repeated the warning at a news conference.

“You really gotta go now. Now is the time,” he said. Earlier, the governor stressed that residents didn’t necessarily need to leave the state, but should “get to higher ground in a safe structure”.

Not everyone was heeding the warning. Andy Bair, owner of the Island Hotel, said he intended to “babysit” his bed-and-breakfast, which predates the Civil War. The building has not flooded in the almost 20 years he has owned it, not even when Hurricane Hermine flooded the city in 2016.

“Being a caretaker of the oldest building in Cedar Key, I just feel kind of like I need to be here,” Bair said. “We’ve proven time and again that we’re not going to wash away. We may be a little uncomfortable for a couple of days, but we’ll be okay eventually.”

Tolls were waived on highways out of the danger area, shelters were open and hotels prepared to take in evacuees. More than 30,000 utility workers were gathering to make repairs as quickly as possible in the hurricane’s wake. About 5500 National Guard troops were activated.

In Tarpon Springs, a coastal community northwest of Tampa, 60 patients were evacuated from a hospital out of concern the weather system could bring a 2.1m storm surge.

After landing in the Big Bend region, Idalia is forecast to cross the Florida peninsula and then drench southern Georgia and the Carolinas on Thursday. Both Georgia Governor Brian Kemp and South Carolina Governor Henry McMaster announced states of emergency, freeing up state resources and personnel, including hundreds of National Guard troops.

“We’ll be prepared to the best of our abilities,” said Russell Guess, who was topping off the fuel tank on his truck in Valdosta, Georgia. His co-workers at Cunningham Tree Service were doing the same. “There will be trees on people’s houses, trees across power lines.”

Idalia pummelled Cuba with heavy rains on Monday and Tuesday, leaving the tobacco-growing province of Pinar del Rio underwater and many of its residents without power.

“The priority is to re-establish power and communications and keep an eye on the agriculture: Harvest whatever can be harvested and prepare for more rainfall,” President Miguel Diaz-Canel said in a meeting with government officials.

State media did not report any deaths or major damage.

With a large stretch of Florida’s western coast at risk from storm surges and floods, evacuation notices were issued in 22 counties, with mandatory orders for some people in eight of those counties.

Many school districts along the Gulf Coast were to be closed today. Several colleges and universities also closed, including the University of Florida in Gainesville. Florida State University in Tallahassee said its campus would be closed through to Friday.

Two of the region’s largest airports stopped commercial operations and MacDill Air Force Base on Tampa Bay sent several aircraft to safer locations.

Asked about the hurricane, US President Joe Biden said he had spoken to DeSantis and “provided him with everything that he possibly needs”.

Ian was responsible last year for almost 150 deaths. The Category 5 hurricane damaged 52,000 structures, nearly 20,000 of which were destroyed or severely damaged.

The National Oceanic and Atmospheric Administration recently said the 2023 hurricane season would be far busier than initially forecast, partly because of extremely warm ocean temperatures. The season runs through November 30, with August and September typically the peak.
