Hurricanes are large vortexes infamous for their spinning, banded shape. Hurricane intensity varies, from the weakest, with 74 mph windspeeds, to a category 5 190 miles-per-hour monster.
Hurricanes could be deadly; recent examples include: Maria, Irma, Harvey, Florence, Michael, etc.
Or they could just drag off to the ocean, as most do.
A average
hurricane season has 7 hurricanes.
2 of these 7 average hurricanes, in average, strike the USA.
The strongest part of a hurricane is the "eyewall", the outer part of the eye of the storm. But, inside of that eyewall; sits the eye, the calmest part of the storm.
Hurricanes lose power over land and colder waters, and gain power in areas of low shear and hot water, which is needed for the storm.
