General Facts about Hurricanes

Hurricanes form in the ocean where the water is 80 degrees Fahrenheit or more. Also if a hurricane is going to form the wind must be blowing in the same direction and the same speed to force air upward from the ocean's surface.

Categories

Hurricanes are categorized by numbers 1-5 with one being the weakest and five being the strongest. A category one hurricane has wind speeds of 74-95 mph. A category two hurricane has wind speeds of 96-110 mph. A category three hurricane has wind speeds of 111-130 mph. A category four hurricane has wind speeds of 131-155 mph. And finally a category five hurricane has wind speeds greater than 155 mph. This is called the Saffir-Simpon Scale.

Naming

Hurricanes are named by alphabetical order. In 1950-1952 hurricanes were named by using the Phonetic alphabet. Then in 1953, hurricanes started being named using women's names.

More General Facts

Some more facts about hurricanes are they maintain strength by drawing heat from warm and moist ocean water. Then once they make landfall hurricanes weaken because there is no warm ocean water to power it.

Hurricane Season

Hurricane season in the atlantic ocean is from mid August to late October. During this time take special precausions to hurricanes because they can hit anywhere.

Hurricane Katrina caused around 12,000 deaths and estimated $105,840,000,000 in damage. She was the costliest hurricane on record to hit the U.S. She formed from a combination of a tropical wave, an upper level trough, and the mid-level remnants of tropical depression 10.
