Hurricanes are formed over warm water with low atmospheric pressure, this pulls warm moist air towards the surface. Coriolis causes the wind to spiral counter clock wise in the Northern hemisphere and clock wise in the Southern hemisphere. When a hurricane makes landfall it loses power because it is leaving water and the hurricane is powered by water. The hurricane season is June, July, August, September, October, and December.
The Saffir-Simpson scale is used to categorize hurricanes. In the Saffir-Simpson scale you categorize hurricanes by their wind speed. The category wind speeds are 1-74 to 95 mph 2-96 to 110 mph 3-111 to 130 mph 4-131 to 155 mph 5-higher than 155 mph. Hurricanes are named after boy and girl names. In the early 1900's hurricanes were named after girl names. In 1979 boy names were added and if the storm was strong enough then the hurricane name would be retired.
