Hurricane damage. Fallen trees obstructing a road following 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 Lili, which passed through the city of Lafayette in Louisiana, USA on 3 October, 2002. It was the first hurricane to make landfall in the USA since 1999.
