Hurricane Melissa made landfall on Cuba early on Wednesday after devastating swathes of Jamaica with violent 185mph winds.
Greater than 700,000 individuals have been evacuated from their houses in Cuba because the Caribbean island of Jamaica reeled from an estimated $22 billion (£16.6 billion) value of injury, with cities submerged and houses blown aside.
Help teams are nonetheless working to evaluate the complete extent of the harm introduced by the storm, with at the very least three individuals reported to have died on Tuesday. A complete of seven have been killed throughout Jamaica, Haiti and the Dominican Republic.
Specialists say that the storm’s highly effective winds and its gradual tempo, possible exacerbated by local weather change, have allowed an enormous hurricane to linger within the area for optimum harm.

Jonathan Porter, chief meteorologist at AccuWeather, stated that the storm was “a dire scenario unfolding in gradual movement”, noting that “slow-moving main hurricanes usually go down in historical past as among the deadliest and most harmful storms”.
“The harm from this historic hurricane landfall is devastating. This was the primary direct strike from a Class 5 hurricane in Jamaica’s recorded historical past,” he stated.
“Melissa had a decent internal core with the strongest winds roughly 20 miles throughout because it moved throughout western Jamaica. It could be a slim path, however there might be important destruction,” he added, warning that the harm would possibly look just like that of ‘extreme’ EF3 and EF4 tornadoes, as seen in america.
The Enhanced Fujita Scale offers scores from EF0 to EF5, and EFU for unknown, score twister depth based mostly on harm. EF3 have wind speeds of 136-165mph and trigger ‘extreme harm’. EF4 have speeds of 166-200mph and trigger ‘devastating harm’, lowering well-built houses to mess and flipping over massive, heavy autos.

David Simon, professor of improvement geography at Royal Holloway, College of London, stated: “Hurricane Melissa is especially devastating due to the advanced set of interacting elements driving it and the character of the locations the place it has made and can nonetheless make landfall.”
“Local weather change is growing ocean temperatures, which will increase evaporation,” defined Prof Simon, who’s a lead creator on the IPCC’s Particular Report on Local weather Change and Cities, to be printed in March 2027.
“Air circulating within the low-pressure system picks this up and sophisticated physics results in a strengthening and deepening vortex that may attain many hundreds of metres into the sky.”
Hurricanes use heat water to type and strengthen. Evaporation creates a mass of heat, moist air, which rises and creates an space of low strain on the ocean’s floor.
Extra air from areas with greater strain then pushes into the low-pressure space, which in flip additionally turns into heat and rises, fuelling the method. As the nice and cozy air cools, the water within the air kinds clouds. The clouds and wind start to develop and spin, moved by the warmth and evaporation of the ocean.
Because the earth rotates, the storm begins to spin, forming an eye fixed on the centre, the place air strain stays lowest. A hurricane – outlined as having wind speeds of at the very least 74mph – with sooner wind speeds won’t essentially transfer extra rapidly via a area.

Hurricanes are in reality now travelling extra slowly than they as soon as did, leading to extra sustained harm, says the Surroundings Protection Pressure advocacy group. One principle is that the winds that steer a hurricane transfer slower in a hotter local weather, probably implicating local weather change.
“Melissa is shifting unusually gradual – reportedly at 2–5 miles per hour – which implies that it turned notably intense earlier than putting Jamaica’s southwest coast final night time. Equally, it spent longer over Jamaica, thus exposing the whole lot in its monitor to extended impacts,” Prof. Simon instructed The Impartial.
Warming oceans additionally possible contribute to the speedy intensification of hurricanes like Melissa, whose winds escalated from 70mph to 140mph in simply sooner or later.
Akshay Deoras, a meteorologist on the College of Studying, stated: “We’re residing in a hotter world, and meaning hurricanes usually tend to intensify rapidly, particularly close to coastlines.
“That a part of the Atlantic is extraordinarily heat proper now — round 30 levels Celsius, which is 2 to three levels Celsius above regular.
“And it’s not simply the floor. The deeper layers of the ocean are additionally unusually heat, offering an unlimited reservoir of vitality for the storm.”
Not all tropical cyclones will go the identical ‘speedy intensification’ as Melissa, stated Bernadette Woods Placky, chief meteorologist at Local weather Central, however the probability of it occurring would enhance in “our hotter world”.

AccuWeather stated that Melissa was tied because the strongest recorded landfall on document within the Atlantic basin.
Whereas the harm to Jamaica continues to be being assessed, they stated the preliminary estimate of whole harm and financial loss to the island was $22billion (£16.6billion).
Jamaica had by no means earlier than been recognized to take a direct hit from a Class 4 or 5 storm, and the federal government known as for international support even because it ready for Melissa’s arrival.
James Waddington, World Safety Director at Worldwide SOS, a safety threat administration firm, instructed The Impartial that the instant dangers to individuals in Cuba had been additionally “extreme”.
“We’re notably involved in regards to the potential for widespread infrastructure harm, energy outages, and flooding, which might considerably affect entry to important providers and hinder emergency response efforts for these most in want.”
He warned that individuals in affected areas on the island had been in danger from storm surges, flash flooding and flying particles.
