At the surface wind flow counterclockwise and in, then flow aloft clockwise and out. There is a low at surface and a high aloft. Hurricanes form in areas with ocean temperatures of 80 degrees Fahrenheit and will die if ocean temperatures are below that. Remember warm ocean temperatures cause surface lows. A minimal hurricane requires sustained winds of 74 mph or more.
Hurricanes generally move from east to west .
Hurricanes often originate as clusters of strong thunderstorms . When these clusters cross into waters with surface temperatures of 82 degrees or higher, they can intensify into hurricanes. 82 degrees is the minimum water temperature that can support a hurricane. Hurricanes that stay on a track at a southerly latitude over such warm water tend to have the longest duration. Therefore, hurricanes will dissipate if they move over colder waters.
