Hurricanes

What is a Hurricane?

A hurricane is a powerful, rotating storm system with a low-pressure center, strong winds, and heavy rainfall. It typically forms over warm ocean waters and can cause extensive damage to coastal areas when it makes landfall.

Formation of Hurricanes

Hurricanes form over warm ocean waters, where the heat and moisture from the ocean fuel the development of the storm. As the warm air rises, it creates an area of low pressure at the surface. This low-pressure system then draws in more warm, moist air, creating a cycle of rising air and condensation, leading to the formation of the hurricane.

Parts of a Hurricane

A hurricane consists of the eye, eyewall, and rainbands. The eye is the center of the storm and is typically calm with clear skies. Surrounding the eye is the eyewall, which contains the strongest winds and heaviest rainfall. The rainbands are bands of clouds and thunderstorms that spiral outward from the eyewall.

Effects of Hurricanes

Hurricanes can cause widespread destruction through high winds, storm surges, and flooding. They can damage buildings, uproot trees, and cause power outages. Storm surges, which are large waves driven by the hurricane's winds, can lead to coastal flooding. Heavy rainfall can also cause inland flooding and landslides.

Staying Safe During a Hurricane

It is important to have a plan in place to stay safe during a hurricane. This includes having an emergency kit with supplies such as water, food, flashlights, and batteries. It is also important to stay informed about the storm's progress and follow evacuation orders if necessary.
