Cyclones, also known as hurricanes or typhoons, are large low-pressure systems that suck air in forcefully, resulting in circulating winds of 119 to over 249 kilometers (74 to over 155 miles) an hour.

They usually form over warm ocean water in the tropics and subtropics. Lightning flashes are more likely to occur over land than water, and most often in the tropics, where more heat provides more energy to produce thunderstorms. The hotspot in Venezuela occurs where warm, moist air from the Caribbean Sea encounters cold air from the Andes mountains.
