The Atlantic hurricane season starts on June 1 and lasts through Nov. 30 — though it usually peaks between August and September.
Hurricanes are powerful tropical weather systems with clear circulation and winds. When hurricanes move onto land, they sweep the ocean inward. They make heavy rains and floods. Hurricanes are grouped into categories based on the wind speed. Most damage caused by hurricanes is from flooding, not the strong winds.
On a worldwide scale, May is the least active month, while September is the most active. In the Northern Atlantic Ocean.
