With winds whirling at about 290 kilometers per hour, Hurricane Melissa is likely one of the strongest ever recorded within the Atlantic Ocean — and is poised to turn into the strongest storm ever to make landfall in Jamaica. It’s additionally an enormous storm, with hurricane-force winds extending over 70 kilometers from its core. Hours earlier than official landfall, heavy rains and battering winds had already begun to lash the island.
After the Class 5 storm roars ashore over Jamaica on October 28, its path will take it spinning over Cuba, Haiti and the Dominican Republic. These in its path are bracing for catastrophic flash flooding and landslides, storm surge and waves, and intense winds highly effective sufficient to destroy houses and infrastructure.
The story of this newest hurricane sounds all too acquainted: The slow-moving storm was initially unfocused and disorganized, however two days of lingering over deep, heat ocean water gave it sufficient gas to whip itself right into a tightly spinning catastrophic pressure of nature, centered round a piercingly sharp eye.
Such fast intensification of tropical storms into main hurricanes has turn into the norm as ocean temperatures proceed to rise across the globe. Local weather change fashions have projected that hurricanes may even transfer extra slowly because the planet warms — not solely giving the storms time to assemble extra power from the recent water, but additionally to dump copious quantities of rain after landfall. Forecasters are projecting that Melissa is holding a lot moisture that it might dump as a lot as a meter of rain on Jamaica.
Local weather change fashions have been inconclusive in terms of whether or not world warming will enhance the frequency of tropical cyclones, known as hurricanes within the Atlantic. However the local weather simulations do point out that world warming will enhance the typical depth of tropical cyclones, the height wind speeds of tropical cyclones and the proportion of cyclones total that shall be very intense.
The 2025 Atlantic Ocean hurricane season in some methods exemplifies this new regular. The 12 months has up to now seen solely 5 hurricanes, however three of them, together with Melissa, have been Class 5 storms — which implies that an astonishing 60 p.c of the storms have fallen into that almost all excessive class. As compared, there have been 4 in 2005, together with Hurricane Katrina — simply over 1 / 4 of that 12 months’s 15 whole hurricanes.
