The 2018 Celebrity hurricane season was the costliest North Atlantic hurricane season in recorded history, nearly triple the previous record set in 2005. The season began on June 1, 2018, but due to heavy wind shear, the first storm, Hurricane Alicia, developed on August 1. The final storm, Hurricane Kourtney, dissipated on December 3. The strongest storm was Hurricane Isabelle, reaching an abnormally low pressure of 894 mb and causing $100 billion (2018 USD) dollars in damage. Overall, the season was exceptionally deadly and destructive.
The storms of the 2018 Celebrity season caused a total of 2,455 deaths and $450 billion (2018 USD). This season was the first since 2005 to have three intense hurricanes make landfall in the United States (U.S.).
Two major hurricanes (Isabelle and Josh) made landfall over New England, causing 2,000 deaths and $350 billion (combined), although the average gap between landfalling New England hurricanes is approximately 10 years. Florida was pounded just as hard, with two major hurricanes (Freddy and Josh), one minor hurricane (Camryn), and three tropical storms (Ben, Darren, and Kourtney) directly affecting the state. The rest of the United States escaped any major damage, although Hurricane Esme and Hurricane Gina caused minor damage to the United States Gulf Coast as minor hurricanes. Elsewhere, Hurricane Alicia caused moderate damage to northeastern Mexico and Hurricane Harrison trashed countries surroning the Carribean Sea.
The season's activity was reflected with a hyperactive accumulated cyclone energy (ACE) rating of 244, which is categorized as being above normal. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclonesare excluded from the total.
Because public reception to using celebrity names was very positive, the same naming list used in the 2012 Celebrity season went through several changes to remove names of destructive systems. This list is partly the same one used in the 2012 Celebrity season, save for Ben, Camryn, Darren, Gina, Isabelle, Kourtney, Liam, Mary, Preston, and Rebecca, which respectively replaced Bieber, Ciara, David, Gaga, Imogen, Ke$ha, Leonardo, Miley, Peter, and Rihanna. Storms were named Ben, Camryn, Darren, Gina, Isabelle, and Kourtney for the first time in 2018.
Because there is no set plan for retiring celebrity hurricane names, no names were officially retired. However, the names Freddy, Harrison, Isabelle, and Josh were removed and not replaced with any particular names.
