Category 5[2]
Criterion sustained winds[2]
Wind threshold 252 km/h or more[2]
Level most intense[2]
Damage catastrophic[2]

A Category 5 hurricane is the highest rating on the Saffir-Simpson scale, defined by sustained winds of 252 km/h or more and associated with catastrophic damage.

Context

A Category 5 hurricane is the most intense rating on the Saffir-Simpson scale, based on maximum sustained wind speed [2]. With winds of 252 km/h or more, it causes catastrophic damage [2]. Well-built homes suffer total roof failure and wall collapse, and fallen trees and power poles can isolate entire neighborhoods [2]. Power outages may last weeks or months, leaving most of the area uninhabitable [2]. Historical examples include Hurricane Katrina, Hurricane Sandy, and Hurricane Dorian, though not all reached Category 5 at landfall.
