Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. The generic, scientific term for these storms, wherever they occur, is tropical cyclone.
Warm water heats the air causing it to rise really quickly, then it gets pushed aside as it cools. Hurricanes are tropical storms where the winds get faster than 118 km/h (73 mph). The storms have a central area of calm known as the "eye", which is the funnel through which the warm air rises
According to Jeff More Hurricane Patricia is expected to be the strongest, most powerful hurricane ever recorded. It's headed towards Mexico at dangerous speeds as of October 23, 2015, but we won't know what the damage is like until after the weekend. Patricia is supposed to hit the coast of Acapulco and Puerto Vallarta - tourist hotspots on the Pacific Coast of Mexico.
