What makes up a hurricane?

The ingredients for a hurricane include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds aloft. If the right conditions persist long enough, they can combine to produce the violent winds, incredible waves, torrential rains, and floods we associate with this phenomenon.

Each year, an average of 10 tropical storms develop over the Atlantic Ocean, Caribbean Sea and Gulf of Mexico. Many of these remain over the ocean. Six of these storms become hurricanes each year. In an average three-year period, roughly five hurricanes strike the United States coastline, killing approximately 50 to 100 people anywhere from Texas to Maine. Of these, two are typically “major” or “intense” hurricanes, with winds greater than 110 mph.
