Hurricane Milton intensified rapidly on Monday, with dangerously strong winds and storm surges forecast for Mexico’s Yucatan Peninsula before the storm is set to slam into Florida in the coming days.

The latest hurricane in the Gulf of Mexico comes close behind deadly Hurricane Helene and some Florida residents have been ordered to evacuate for the second time in weeks.

The US National Hurricane Centre (NHC) said Milton was “an extremely dangerous Category 4 hurricane,” on a scale of five, packing maximum sustained winds of 240 kilometres an hour.

Florida Governor Ron DeSantis, who has declared 51 of his state’s 67 counties under a state of emergency, said the race was on to clear damage from Hurricane Helene ahead of Milton’s mid-week arrival.

“We need as much of this debris picked up as possible,” DeSantis told a press conference. “This creates a safety hazard, and it also will increase the damage that Milton could do with flying debris.”

The NHC warned of storm surges raising water levels by 1.5 metres along the Yucatan Peninsula and large, destructive waves on the coast. Storm surges and rainfall of 250 millimetres are expected to cause havoc in Florida, causing flash flooding in urban areas.

Emergency workers are still struggling to provide relief in the aftermath of Helene, which killed at least 230 people in several states across the US southeast.

Political stakes

Efforts after Helene have been hit by a wave of politically motivated false claims ahead of the November 5 presidential election.

Among the litany of disinformation is the falsehood pushed by Republican candidate Donald Trump that funds have been misappropriated by his rival for the White House, Democrat Kamala Harris, and redirected toward migrants.

Deanne Criswell, head of the Federal Emergency Management Agency (FEMA), dismissed the claims as false.

She warned on Monday that “these storms are bringing more water than they ever have and so while we have the wind risk, the water is what’s killing people, so please listen to your local officials, seek safety.”

Researchers say climate change likely plays a role in the rapid intensification of hurricanes because there is more energy in warmer oceans for them to feed on.

President Joe Biden was briefed on Milton and said in a statement his administration was readying “life-saving resources”.

Hurricane Helene hit the Florida coastline on September 26 as a Category 4 storm, dumping torrential rainfall, and later causing massive flooding in remote inland towns in states further north, including North Carolina and Tennessee.

The storm was the deadliest natural disaster to hit the mainland United States since 2005’s Hurricane Katrina, with the death toll still rising. Many communities, particularly those in mountainous areas, have been left without power and drinking water.

DeSantis said Florida has had power restored since last week, but that many electrical teams were deployed in other states badly hit by Helene.

“There are still hundreds of thousands of people without power in some of these other states that got hit by Helene, so there are crews working there, but they’re bringing people in from far and wide to be able to respond” to Milton, he said.

He warned Milton will “remain a hurricane at some level all the way through exiting the east coast of Florida”.
