Hurricanes

A hurricane is a powerful and destructive storm with strong winds, heavy rain, and thunderstorms. It forms over warm ocean waters and can cause significant damage to coastal areas.

Formation of Hurricanes

Hurricanes form when warm air over the ocean rises and cools, creating an area of low pressure. As more warm air rises to fill the low pressure area, it creates a rotating system of winds. When the winds reach a certain speed, the storm is classified as a hurricane.

Anatomy of a Hurricane

A hurricane has a well-defined center called the eye, which is surrounded by the eyewall where the strongest winds and heaviest rains are found. The outer bands of the hurricane also bring strong winds and rain.

Stages of a Hurricane

1. Tropical Disturbance: A cluster of thunderstorms over warm ocean waters.
2. Tropical Depression: When the cluster of storms develops a well-defined circulation.
3. Tropical Storm: When the system's winds reach a speed of 39-73 mph.
4. Hurricane: When the winds reach 74 mph or higher.

Effects of Hurricanes

Hurricanes can cause storm surges, flooding, and wind damage. They can also lead to power outages, infrastructure damage, and loss of life. It is important to be prepared for hurricanes and heed evacuation orders to stay safe.
