Ten years later, the 2005 hurricane season remains the most active on record.
Barry Keim, Louisiana’s state climatologist, says that in 2005, “The sea surface temperatures were off the charts.” Keim explains that hurricanes need warm water to develop. The warmer the water, the stronger hurricanes can potentially become.
There were 28 named storms in 2005. “It was a crazy year,” Keim says. The last storm of the season, Tropical Storm Zeta, formed on December 30th—a full month after what should have been the end of hurricane season.
