2005 Atlantic cyclone season

The 2005 Atlantic cyclone season produced 21 tropical systems, twenty tropical storms, ten hurricanes, with five majors. Three names from this season were retired, being Hurricane Elena, Hurricane Iolanthe, and Hurricane Sid. It was highly active due to the developing La Niña event as well as vigorous African waves. The season did not start up until late July, but once it did, it set off at a blazing pace. September had an incredible nine systems active during the month. Ten of the systems developed in the main region between the Caribbean and Africa.
