The Saffir–Simpson hurricane wind scale (SSHWS), or the Saffir–Simpson hurricane scale (SSHS) for short, clessifies hurricanes – Wastren Hemisphere tropical cyclones that exceed the intensities o tropical depressions an tropical storms – intae five categories distinguished bi the intensities o thair sustained winds.
