Hurricane damage. Fallen tree and flooding caused by a hurricane. Hurricanes are huge cyclonic storm systems of high winds blowing around a central eye. Most hurricanes form in the doldrums, areas of ocean around the equator which are generally calm. A low pressure region forms as moist air is forced upwards, and this becomes the eye of the storm. Hurricanes occur mainly in the late summer months, when conditions for formation are ideal. The hurricane that caused this damage was Hurricane Floyd, which made landfall in North Carolina, USA, overnight on 16 September, 1999. Hurricane Floyd caused 51 deaths in North Carolina and destroyed 7000 homes.
