Irma set records

Before crashing into Florida, Hurricane Irma set all sorts of records for brute strength as it flattened Caribbean islands and swamped the Florida Keys. Irma’s assault — so soon after Harvey’s deluge of Houston — marked the first time the U.S. was hit by two Category 4 storms in the same year.

Irma hit the Sunshine State as a big wide beast, though not quite the monster it once was shaping up to be. Earlier, it was the most powerful recorded storm in the open Atlantic. But as the once-Category 5 storm neared the U.S. mainland, it lost some oomph after running into the northern coast of Cuba.

Winds dropped to a quite potent 185 km/h by the time Irma made landfall on Marco Island, on the Florida peninsula, still a major and dangerous hurricane yet not near its 297 km/h former self when it set a record Tuesday for the most powerful storm in the open Atlantic. And on top of that, Irma avoided what could have been its most destructive paths along the Florida peninsula — over Miami and the heavily developed Atlantic seaboard. “There’s a huge difference between a (Category) 3 and 5 when it makes landfall,” said private meteorologist Ryan Maue of WeatherBell Analytics. “Barbuda is an example of that. It was wiped.”

“This is obviously not the worst case scenario for Florida overall,” Maue said. Had the centre of Irma hit Florida 32-50 kilometres to the east “it would have been much worse.”
