What are hurricanes?

Hurricanes are powerful tropical storms that form over warm ocean water. They are a type of tropical cyclone, and they bring strong winds, heavy rain, storm surge, and sometimes tornadoes.

Quick Scoop

  • Hurricanes form over tropical or subtropical waters when conditions are right.
  • [9][1]
  • They start as a tropical depression, become a tropical storm, and are called a hurricane when sustained winds reach 74 mph or higher.
  • [5][1][9]
  • They can be very dangerous because of flooding, high winds, and rising seawater called storm surge.
  • [3][9]

How they work

Warm ocean water fuels the storm. As moist air rises, it creates a low-pressure system, and Earth’s rotation makes the storm spin. When the storm strengthens enough, it develops an eye at the center and organized bands of thunderstorms around it.

  • [8][3]
  • Flooding: from heavy rain and overflowing rivers.
  • [9][3]

Bottom line

Hurricanes are large, rotating storms powered by warm ocean water, and they become especially dangerous when they reach land. If you want, I can also give you a kid-friendly explanation or a 1-sentence definition.
