In the movie you can see the storm starting to form in the Atlantic on August 24 and becoming more and more organized as it moves over the warm waters of the Gulf of Mexico. Mousing over the symbol for each weather system displays details for that system; A pre-existing disturbance, warm ocean water, low atmospheric stability, sufficient Coriolis force, moist mid-atmosphere, and upper atmosphere divergence are all important factors for hurricane formation. They produce strong winds, storm surge flooding, and heavy rainfall that can lead to inland flooding, tornadoes, and rip currents.As storm systems strengthen into hurricanes, the surface winds move continuously in a circular motion. Lightning is responsible for many fires around the world each year, and causes fatalities. As the warmed, moist air rises and cools off, the water in the air forms clouds.

Because this air moves up and away from the surface, there is less air left near the surface.
(These satellites, built by NASA and operated by the National Oceanic and Atmospheric Administration (NOAA), save lives by helping weather forecasters predict and warn people where and when these severe storms will hit land.Here is a movie of Hurricane Katrina, which struck the coast of Louisiana, Alabama and Mississippi on August 29, 2005, as a Category 3. How Hurricanes Form and Die. Hurricanes are the most violent storms on Earth.
Climate - Climate - Formation of tropical cyclones: Tropical cyclones represent still another example of air-sea interactions. And when the wind speeds reach 74 mph, the storm is officially a "tropical cyclone," or hurricane.Tropical cyclones usually weaken when they hit land, because they are no longer being "fed" by the energy from the warm ocean waters. She writes for several websites. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called "hurricanes."
Weather forecasters draw a cone showing where they think the hurricane is … The direction of circulation is different depending on where the storm is located: it is counter-clockwise in the Northern hemisphere and clockwise in the Southern hemisphere.These rotating winds lead to the development of the characteristic “eye” of the hurricane, the calm, clear center of the storm. Many hazardous weather events are associated with thunderstorms. Coastal communities are particularly vulnerable as rising sea levels compound storm surge flooding.
