to be a Category 3 storm. Likewise, an intensity of 135 kn (~155 mph, and thus Category 4) is 250.02 km/h, which, according to the definition used before the change would be Category 5. To resolve these issues, the NHC had been obliged to incorrectly report storms with wind speeds of 115 kn as 135 mph, and 135 kn as 245 km/h. The change in definition allows storms of 115 kn to be correctly rounded down to 130 mph, and storms of 135 kn to be correctly reported as 250 km/h, and still qualify as Category 4. Since the NHC had previously rounded incorrectly to keep storms in Category 4 in each unit of measure, the change does not affect the classification of storms from previous years. The new scale became operational on May 15, 2012.

Only a few types of structures are capable of surviving intact, and only if located at least 3 to 5 miles (5 to 8 km) inland. They include office, condominium and apartment buildings and hotels that are of solid concrete or steel frame construction, multi-story concrete parking garages, and residences that are made of either reinforced brick or

Flooding near the coast destroys smaller structures, while larger structures are struck by floating debris. A large number of trees are uprooted or snapped, isolating many areas. Additionally, terrain may be flooded well inland. Near-total to total power loss is likely for up to several weeks and water will likely also be lost or contaminated. 1089: 921: 586: 1257: 1557:, and suggested that Category 6 would begin at 195 mph (85 m/s; 170 kn; 315 km/h), with a further hypothetical Category 7 beginning at 230 mph (105 m/s; 200 kn; 370 km/h). In 2024 another proposal to add "Category 6" was made, with a minimum wind speed of 192 mph (309 km/h), with risk factors such as the 1455:, a few newspaper columnists and scientists brought up the suggestion of introducing Category 6, and they have suggested pegging Category 6 to storms with winds greater than 174 or 180 mph (78 or 80 m/s; 151 or 156 kn; 280 or 290 km/h). Fresh calls were made for consideration of the issue after 386:, and other important factors, but SSHWS defenders say that part of the goal of SSHWS is to be straightforward and simple to understand. There have also been proposals for the addition of higher categories to the scale (which would then set a maximum cutoff for Category 5), but none have been adopted as of July 2024. 1459:

In 2012, the NHC expanded the windspeed range for Category 4 by 1 mph in both directions, to 130–156 mph, with corresponding changes in the other units (113–136 kn, 209–251 km/h), instead of 131–155 mph (114–135 kn, 210–249 km/h). The NHC and the

In 2009, the NHC eliminated pressure and storm surge ranges from the categories, transforming it into a pure wind scale, called the Saffir–Simpson Hurricane Wind Scale (Experimental) . The updated scale became operational on May 15, 2010. The scale excludes flood ranges,
