Hurricanes are the name given to a tropical cyclone in which winds reach maximum sustained speeds of at least 64 knots (74 mph; 118.5 km/h) that arise in the Atlantic or East Pacific. In other parts of the world, the same phenomenon goes by other names – as typhoons in the West Pacific and as cyclones/tropical storms in the Indian Ocean and around Australia.
