The recently concluded Atlantic hurricane season was the busiest since 2005 and one of the most damaging on record, according to the Insurance Information Institute.

It was the first time three Category 4 storms – Harvey, Irma and Maria – made landfall in the US and its territories.

There were 17 named storms and 10 reached hurricane strength, surpassing an average season of 12 named storms and six hurricanes.

“Three of the 17 storms that formed… accounted for the lion’s share of damage,” the institute’s non-resident scholar Philip Klotzbach said, referring to Harvey, Irma and Maria.

“While the final damage estimates are still being tallied, this season will certainly go down as one of the most devastating Atlantic hurricane seasons of all time.”

The season runs from June 1 to November 30.
