PRESENTATION OUTLINE
A hurricane is a violent tropical cyclone. A tropical storm becomes a hurricane if it’s winds reach 119 km/hr (74 mph). Warm ocean water provides the energy a storm needs to become a hurricane. Usually, the surface water temperature must be 26 degrees Celsius or 79 degrees F or higher to form to form a hurricane. The water evaporates until it twists. When a hurricane reaches land, it loses its source, the ocean, and slows down. A storm first starts as a tropical disturbance This can turn into a tropical depression. A tropical depression becomes a tropical storm when winds reach 63 km/hr. And a tropical storm becomes a hurricane if it’s winds reach 119 km/hr. Some people die from indirect and direct fatalities. A direct fatalities is when someone dies from the hurricane such as drowning or building falling down from hurricane. Indirect fatalities are less straightforward than direct. Indirect fatalities are other deaths and not from hurricanes such as heart failures.
