More powerful hurricanes are due to higher sea temperatures. Now that the earth is warming up, do we need a category 6 on the hurricane scale?
Higher sea temperatures will in the future lead to more powerful hurricanes and more super typhoons.
The American categories for tropical hurricanes in the Atlantic and the Eastern Pacific indicate the extent of the expected destruction.

Because today's highest category, Category 5, is "devastating," we don't need Category 6, although the researchers expect hurricanes to become 5 percent more powerful in the future.
The first seven 'category 6 hurricanes' have caught us
Currently the hurricane scale goes up to 288 km / h in the most turbulent minute. If a category 6 were introduced, the limit would be for winds that have an average speed of more than 288 km / h for one minute.
Seven hurricanes have already been registered above the Atlantic Ocean that would fall into that category. In 2017, Hurricane Irma reached wind speeds of 295 km / h.
Another category 6 hurricane is the super typhoon Haiyan, who hit the Philippines in 2013 with winds of 315 km / h.
The new limit is above 288 km / h
Average wind measured during one minute
- Category 1: 119-153 km / h
- Category 2: 154-177 km / h
- Category 3: 178-208 km / h
- Category 4: 209-251 km / h
- Category 5: 252-288 km / h
- EVT. CATEGORY 6 > 288 km / h
