There are four conditions
that allow a hurricane to exist: low
pressure (reinforced by the hurricane) warm
temperatures (often in the summer) moist
areas (over the ocean) tropical wind patterns
(close to the Equator)
Hurricanes begin when raindrops condense out of warm, moist air. That releases heat, which then makes the air convect. When this happens in a low pressure zone near the equator, it can create an organized system of clouds and storms called a tropical depression. As more moist air is swept up and more rain condenses out, the depression gets stronger, creating a tropical storm. If enough heat is added to the system, it becomes a hurricane with strong winds, an eye, and storm surge.
