(NEXSTAR) – Hurricane Milton intensified from a Category 1 to a Category 5 hurricane connected the Saffir-Simpson Hurricane Wind Scale implicit the people of Monday greeting arsenic it progressed toward Florida, according to the National Hurricane Center.
It was besides expected to bring dense rainfall and tempest surges to parts of Florida earlier weakening and making landfall.
People surviving successful the Gulf area’s astir predominant hurricane paths, meanwhile, are nary alien to storms. But the accelerated intensification of these storms? That mightiness beryllium comparatively new.
Rapid intensification is defined by the National Hurricane Center arsenic an summation of astatine slightest 30 knots (about 35 mph) successful maximum sustained winds wrong a 24-hour period, which tin mean a leap of 2 categories connected the Saffir-Simpson scale.
As it presently stands, accelerated intensification has been observed successful astir 80% of each large hurricanes successful the North Atlantic “and astir each class 4 and 5 hurricanes,” the National Oceanic and Atmospheric Administration (NOAA) said earlier this year.
Scientists person besides recovered grounds to suggest that storms are much often experiencing accelerated intensification erstwhile compared to cyclones successful years past, but it’s unclear if each of those instances tin beryllium attributed to clime change, oregon if “natural variables” tin relationship for some, according to an October 2024 report from the Congressional Research Service.
Researchers, however, person so observed an summation successful rapidly intensifying storms successful planetary basins, arsenic good arsenic a important spike successful accelerated intensification happening conscionable offshore, alternatively than retired successful the unfastened ocean.

Rising water temperatures (both connected the aboveground and below) arsenic good arsenic humid aerial — which often accompanies warmer h2o — are two of the main conditions that promote cyclone development, the bureau says.
Such rapidly intensifying storms volition lone go “more likely” successful the future, according to the Congressional report.
“According to NOAA, scientists person mean to precocious assurance that tropical cyclone intensities globally volition apt summation connected mean nether a [2 degrees Celsius] of planetary aboveground somesthesia increase, and that the planetary proportionality of tropical cyclones that scope precise aggravated levels (Category 4 and 5) volition besides apt summation implicit the 21st century,” the study states.
“Scientists besides task these changes for the Atlantic basin, specifically,” the writer added.
An summation successful rapidly intensifying cyclones, too, is particularly problematic for those successful the paths of the forecasted storms. Rapid intensification is hard to predict, meaning residents successful the people areas not beryllium afloat alert of the strength of a hurricane — and possibly not prepared to evacuate — until it’s excessively late.
Milton is expected to marque landfall successful Florida connected Wednesday, albeit arsenic a weaker Category 3 hurricane, Nexstar's WFLA reported Monday.
Still, officials are urging residents of immoderate parts to hole and evacuate earlier it’s excessively precocious to bash so.
“This is the existent woody present with Milton,” Tampa Mayor Jane Castor said, the Associated Press reported. “If you privation to instrumentality connected Mother Nature, she wins 100% of the time.”
