{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}favorable for Atlantic storm formation in 2005.
[00:00:28.35]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}We begin with the ocean;

[00:00:48.68]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}degrees; the threshold favorable for hurricane development.

[00:01:04.93]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}Atlantic-based hurricanes typically form between June
[00:01:08.97]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}and November. Hurricanes often start as 
[00:01:12.99]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}atmospheric disturbances of the coast of West Africa. Once out 
[00:01:17.01]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}into the warm summer waters of the Mid-Atlantic, some ripples 
[00:01:21.12]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}begin to rotate and feeding of off warm water strengthen into
[00:01:25.21]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}hurricanes. Hurricanes require warm water to heat
[00:01:29.31]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}air above the ocean causing a drop in air pressure. Lower
[00:01:33.39]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}air pressures sucks more water vapor into the storm, causing
[00:01:37.46]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}storms to strengthen. As hurricanes pass over warm water
[00:01:41.52]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}they leave trails of relatively cooler water so called,
[00:01:45.57]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}cold water trails. Numbers displayed over storms

[00:02:22.20]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}phenomena; only about 80 or 90 appear worldwide

[00:02:54.65]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}superlatives. An average year produces roughly 10
[00:02:58.71]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}storms, 27 named storms formed in 2005.
[00:03:02.75]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}An average year produces 6 hurricanes, 
[00:03:06.79]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}15 formed in 2005. An average year
[00:03:10.82]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}produces two major hurricanes. Seven formed in 
[00:03:14.85]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}2005 on average one category 5
[00:03:18.87]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}hurricane forms every three years. In 2005
[00:03:22.88]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}there were three Katrina, Rita, and Wilma.
[00:03:26.95]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}Wilma was the most intense Atlantic hurricane ever recorded,
[00:03:31.02]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}Katrina fourth, Rita sixth. But Katrina
[00:03:35.10]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}was the most destructive hurricane ever to hit the United States. The
[00:03:39.17]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}total losses from storms in 2005 include more than 
[00:03:43.23]
{font:Arial}{size:14}{Plain}{textColor:65535, 65535, 65535}1,200 lives and potentially more than 100
