More than 1 million ordered to evacuate Florida's Gulf Coast as Hurricane Milton grinds near

Hurricane Milton was expected to enlarge even as its intensity ebbed on Tuesday as the now-Category 4 storm ground past Mexico's Yucatan Peninsula en route to Florida's Gulf Coast, where more than one million people were ordered to evacuate before the monster storm arrived.

Florida's densely populated west coast, still reeling from the devastating Hurricane Helene less than two weeks ago, braced for landfall on Wednesday.

The U.S. National Hurricane Center said the storm was likely to hit near the Tampa Bay metropolitan area, where some of the three million residents rushed to dispose of mounds of debris left behind by Helene before heeding the evacuation orders. If the hurricane drives directly across the city, it will mark the first time since 1921 that this has occurred.

Despite Hurricane Milton being downgraded to a category 4 storm, Floridians are still bracing for impact, preparing themselves for high winds and storm surges. Milton is coming in on the tail of Hurricane Helene, which hit the state's Gulf Coast only two weeks prior. Evacuation orders have been given for those who live in the storm's projected path.

U.S. President Joe Biden on Tuesday urged those who have been ordered to leave to "evacuate now," saying it was a matter of life and death.

"This could be the worst storm to hit Florida in over a century, and, God-willing, it won't be, but it's looking like that right now," Biden said.

Biden added that he has approved pre-landfall emergency declarations in Florida and is calling on airlines to accommodate evacuations and not engage in price gouging.

The White House said Biden was cancelling a planned trip later in the week to Germany and Africa given the hurricane aftermath of Helene and the expected damage from Milton.

Tampa residents may be unprepared

Florida Gov. Ron DeSantis said on Tuesday that the state would activate 8,000 National Guard members and is staging truck loads of supplies and equipment near the area where the storm is expected to make landfall.

"Now is the time to execute your plan ... but that time is running out," he said during a news briefing, urging residents to heed warnings from forecasters and local evacuation orders.

With maximum sustained winds of 250 km/h, Milton was downgraded from a Category 5 to a Category 4 hurricane on the five-step Saffir-Simpson scale, according to the U.S. National Hurricane Center's latest advisory on Tuesday.

While Floridians are no strangers to storms, Tampa hasn't been in the direct path of a major hurricane in over a century.

In that lapse, the area has exploded in growth. Tens of thousands of Americans moved to the area during the COVID-19 pandemic, with many choosing to settle along barrier islands like Clearwater and St. Petersburg overlooking the normally placid, emerald Gulf waters.

More than 51,000 people moved to the area between 2022 and 2023, making it the fifth-fastest-growing U.S. metropolitan area, according to U.S. Census data.

Longer-term residents, after having experienced numerous false alarms and near misses like Irma in 2017, may be similarly unprepared for a direct hit. A local legend has it that blessings from Native Americans who once called the region home and used to build mounds to keep out invaders have largely protected the area from major storms for centuries.

MIT meteorology professor Kerry Emanuel said a hurricane in Tampa is the "black swan" worst-case scenario that experts have worried about for years.

Catastrophic damage expected

While fluctuations in intensity are expected, Milton is forecast to remain an extremely dangerous hurricane through landfall in Florida, according to the hurricane center. That means catastrophic damage will occur, including power outages expected to last days.

The hurricane centre forecast storm surges of three to 4.5 meters along a stretch of coastline north and south of Tampa Bay.

Fed by warm waters in the Gulf of Mexico, Milton became the third-fastest-intensifying storm on record in the Atlantic Ocean, as it surged from a tropical storm to a Category 5 hurricane — the most powerful category — in less than 24 hours.

Its path from west to east was also highly unusual, as Gulf hurricanes typically form in the Caribbean Sea and make landfall after traveling west and turning north.

"It is exceedingly rare for a hurricane to form in the western Gulf, track eastward, and make landfall on the western coast of Florida," said Jonathan Lin, an atmospheric scientist at Cornell University. "This has big implications since the track of the storm plays a role in determining where the storm surge will be the largest."

Milton is expected to grow in size before making landfall on Wednesday, putting hundreds of miles of coastline within the storm surge danger zone, said Jamie Rhome, deputy director of the National Hurricane Center. The area placed under hurricane warning is home to more than 9.3 million residents.

Expected to pound Yucatan

Milton was expected to pound the northern edge of the Yucatan Peninsula in the early hours of Tuesday. The area is home to the picturesque colonial-era city of Merida, population 1.2 million, Maya ruins popular with tourists and the port of Progreso.

In Florida, counties along the western coast ordered people in low-lying areas to take shelter on higher ground.

Pinellas County, which includes St. Petersburg, said it ordered the evacuation of more than 500,000 people. Lee County said 416,000 people lived in its mandatory evacuation zones. At least six other coastal counties ordered evacuations including Hillsborough County, which includes the city of Tampa.

With one final day for people to evacuate on Tuesday, local officials raised concerns of traffic jams and long lines at gas stations.

Relief efforts remain ongoing throughout much of the U.S. Southeast in the wake of Helene, a Category 4 hurricane that made landfall in Florida on Sept. 26, killed more than 200 people and caused billions of dollars in damage across six states. Asheville and other mountain communities of western North Carolina, hundreds of miles inland, were particularly hard hit.
