Hurricane category 6 could be introduced under new storm severity scale
The current hurricane classification does not consider storm surge and rainfall risks, which cause almost 80% of hurricane-related deaths. A new scale could help people better prepare for storms.
"There have been too many instances of incredible loss of life and destruction because a low category number on the SSHWS [...] did not match the danger of the storm," Jennifer Collins, a professor in the School of Geosciences at the University of South Florida and co-author of the new study, said in a statement. Dubbed the Tropical Cyclone Severity Scale (TCSS), this system has six categories and takes into account wind speed, storm surge and rainfall — the three biggest hazards from hurricanes. Correct identification of the main hazard boosted participants' intent to take relevant precautions, such as shielding their houses against flooding with sandbags and erecting window protections against the wind.
