How Hurricanes Form

Interested in extreme weather events? Then a hurricane—a swirling mass of wind, rain, thunder, and chaos—will intrigue you. Hurricanes begin over tropical and subtropical ocean water. It starts when warm water, moist air, and strong winds collide and create a rotating bundle of thunderstorms and clouds. A hurricane might last a few hours or several days.

 

Some hurricanes roar onto land bringing punishing wind, torrential rain, walls of water, even tornados. The wind, rain, and water surge wreak havoc on the coastline and damage hundreds of miles inland.

 

Violent winds flip cars, sink boats, and rip houses apart. Hurricane winds range from 74 miles an hour (119 kilometers an hour) to 150 ​miles an hour​ (241 kilometers an hour) or more. Wind creates high waves and pushes the water onto shore. The water surge can be 30 feet (9 meters) high. That's as high as a 3-story building. Storm surges cause most of the fatalities and damage.

 

In addition to the storm surge, hurricanes bring rain. Lots of rain. In 2009, a storm hammered Taiwan with 114 inches (290 centimeters) of rain in only three days. Hurricane rains cause landslides, flash floods, and long-term floods.

 

Because meteorologists can predict and track hurricanes, people living in a hurricane's path can stay safe by advance preparation, including an evacuation plan, creating an emergency kit with food, water, and other supplies (don't forget your pets), and most importantly by listening to local authorities on the best ways to stay safe.

 

Hurricane Parts

Eye: The calm center. The eye can be 20-40 miles (32-48 kilometers) wide. In the eye, rather than dark clouds and rain, one might see blue sky or a starry night.


Eyewall: The clouds that swirl around the eye. It has the most intense rain and winds, sometimes as fast as 200 miles an hour (321 kilometers an hour).


Rain bands: Thunderstorms and clouds that spiral in toward the eyewall.
