What is 2017 Atlantic hurricane season?
The '''2017 Atlantic hurricane season''' was the most active since [[2012 Atlantic hurricane season|2012]]. It officially began on June 1 and ended on November 30. It was an [[Accumulated Cyclone Energy|extremely active]] and tragic season. With a damage total of at least $282.16 billion ([[United States dollar|USD]]), it was the [[costliest]] season on record. With over 3,300 deaths, 2017 was the deadliest season since [[2005 Atlantic hurricane season|2005]]. More than 99.7% of the season's damage was due to [[Hurricane Harvey|Harvey]], [[Hurricane Irma|Irma]], and [[Hurricane Maria|Maria]]. [[Hurricane Nate|Nate]], was the worst natural disaster in [[Costa Rica|Costa Rican]] history. Harvey, Irma, Maria, and Nate had their names retired due to their high damage costs and loss of life. Featuring 17 named storms, 10 hurricanes, and 6 major hurricanes, the 2017 season is the fifth active season. Tropical Storm Arlene in April was the first storm of the season that formed on April 19. This was the third consecutive season in which storms form before the official start of the hurricane season. In late August, [[Hurricane Harvey]] became the first major hurricane to make landfall in the United States since [[Hurricane Wilma|Wilma]] in [[2005 Atlantic hurricane season|2005]] and the first Category&nbsp;4 hurricane since [[Hurricane Charley|Charley]] in [[2004 Atlantic hurricane season|2004]]. It also tied the record for the costliest tropical cyclone on record along with the most rainfall dropped by a tropical cyclone in the United States. In early September, [[Hurricane Irma]] became the first Category 5 hurricane to impact the northern [[Leeward Islands]] on record. It later hit the [[Florida Keys]] as a Category 4 hurricane. Irma is the strongest hurricane ever recorded in the Atlantic Ocean outside of the [[Gulf of Mexico]] and [[Caribbean Sea]].<ref>{{Cite web|url=https://twitter.com/NHC_Atlantic/status/905080927948349440|title=#Irma is the strongest #hurricane in the Atlantic basin outside of the Caribbean Sea
