Cyclones are intense rotating storms that form over bodies of water. They are classified as either extra tropical or tropical cyclones. Tropical cyclones develop over tropical oceans and organize into a surface-level wind circulation. Cyclones form through a process where air rises and causes winds to rotate faster, forming a large swirling storm. Cyclones can cause damage through strong winds, heavy rain, power outages, injury and loss of life, and destruction of crops and vegetation. Preparation and mitigation efforts are important to reduce risks from cyclones.
