The primary feature of a hurricane is its intense low-pressure center, known as the eye, surrounded by a powerful system of rotating winds and thunderstorms. Hurricanes typically form over warm ocean waters and are characterized by their organized structure, which includes the eye, an eye wall, and rainbands. The eye is usually calm and clear, while the eye wall contains the strongest winds and heaviest rainfall. These storms can cause significant damage due to strong winds, heavy rainfall, and storm surges when making landfall, and they can lead to flooding, destruction of property, and loss of life in affected areas.
