Hurricanes are intense tropical cyclones that form over warm ocean waters and are characterized by a low-pressure center, organized deep convection, and strong cyclonic surface winds. They derive energy from latent heat released during condensation within deep convective clouds, requiring sea surface temperatures typically above ~26–27 °C, sufficient Coriolis force to initiate rotation, and weak vertical wind shear to maintain structural integrity. Hurricanes exhibit a warm-core structure, an eye and eyewall, and spiral rainbands, and are classified by maximum sustained wind speed. They are central topics in atmospheric science, climate research, and risk modeling due to their role in heat transport, extreme precipitation, storm surge, and high-wind hazards.
Violent storms battering the central-eastern United States have killed at least 16 people, officials said, with the National Weather Service warning on Saturday of "severe" flash flooding in the coming days.
