From 1850 to 1900 we had 93 landfall hurricanes. From 1900 to 1950 we had 93.
The average is 18.6 per decade. From
1950 to 2000 we had 73. The average is 14.6 per decade. Since 2000 we’ve had
30. The average is 15 per decade. These only affect coastal areas. Hurricanes
appear to be declining. The number of US landfall hurricanes is listed by

Hurricanes form near the equator over warm
ocean waters, where the ocean is at
least 80 degrees F for at least the top 50 meters (about 165 feet) below the
surface.
The term hurricane is used only for the large
storms that form over the Atlantic Ocean or eastern Pacific Ocean. The term
cyclone is used elsewhere.
The second ingredient
for a tropical cyclone is wind.
In the case of
hurricanes that form in the Atlantic Ocean, the wind blowing westward across
the Atlantic from Africa provides the necessary ingredient. As the wind passes
over the ocean's surface, water evaporates (turns into water vapor) and rises.
As it rises, the water vapor cools, and condenses back into large water
droplets, forming large cumulonimbus clouds. These clouds are just the
beginning.
