The 2018 Atlantic hurricane season was the final season in a series of three consecutive active Atlantic hurricane seasons. The season officially started on June 1, 2018, and ended on November 30, 2018. The season was active, with 14 named storms forming, of which eight were hurricanes and four were major hurricanes. The season was also very destructive and deadly, with over $40.8 billion (2018 USD) in damages and 829 deaths caused by the season's storms, although hurricanes Gordon and Leslie were responsible for most of the destruction.
The season's first sytem, Tropical Storm Alberto, developed on June 4, while the final system, Tropical Storm Nadine, dissipated on November 24. The strongest storm was Hurricane Isaac, a Category 4 hurricane that stayed out at sea and had no effect on land as a tropical cyclone. Hurricane Gordon was the season's costliest and most significant storm, causing over $36 billion (2018 USD) in damages and 369 fatalities in the Greater Antilles, Cuba, Florida, and the Southeastern United States. The season's deadliest storm was Hurricane Leslie, a strong Category 2 hurricane that took the lives of 451 people in Jamaica and southeast Cuba.
Initial predictions for the season were somewhat divided, with some agencies citing the possibility of an El Niño developing. However, the El Niño did not develop, with warm-neutral conditions instead developing.

Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes and major (Category 3 or higher on the Saffir-Simpson scale) hurricanes will form during a season and/or how many tropical cyclones will affect a particular country. These agencies include the Tropical Storm Risk (TSR) Consortium of the University College London, the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. Some of these forecasts also take into consideration what happened in previous seasons and an ongoing La Niña event that had recently formed in November 2017. On average, an Atlantic hurricane season between 1981 and 2010 contained twelve tropical storms, six hurricanes, and three major hurricanes, with an Accumulated Cyclone Energy (ACE) index of between 66 and 103 units.
The first forecast for the year was released by TSR on December 7, 2017, predicting a slightly above-average season in 2018, with a total of 15 named storms, 7 hurricanes, and 3 major hurricanes. TSR lowered their forecast numbers slightly on April 5, 2018 to 13 named storms, 7 hurricanes, and 3 major hurricanes. The CSU issued their first forecast for the season on the same day, predicting 13 named storms, 6 hurricanes, and 2 major hurricanes. On April 15, the North Carolina State University released their prediction, calling for 2018 to be a near-average to above-average season, with a total of 11-15 named storms, 4-7 hurricanes, and 1-3 major hurricanes. The next day, The Weather Company released their prediction, predicting an above-average season, with a total of 14 named storms, 7 hurricanes, and 3 major hurricanes. On May 23, NOAA released their prediction, calling for a near-average to above-average season, citing the uncertainty in the state of the El Niño-Southern Oscillation. On May 27, the TSR updated their predictions to close to the same numbers as its December 2017 predictions, citing the decreasing likelihood that an El Niño would develop.
Mid-season outlooksOn June 12, CSU updated their forecasts to include Tropical Storm Alberto. Due to the low chances that an El Niño would develop, as well as warmer than average sea surface temperatures in the tropical Atlantic, they raised their numbers to 14 named storms, 6 hurricanes, and 2 major hurricanes, although they stressed on the possibility of warm-neutral or weak El Niño conditions developing by the peak of the season. The following day, the United Kingdom Met Office (UKMO) released its forecast, predicting a slightly above-average season with 13 named storms, 7 hurricanes, and no prediction on the number of major hurricanes.
Tropical Storm Alberto
|Tropical storm (SSHWS)|
|Duration||June 5 – June 7|
|Peak intensity||50 mph (85 km/h) (1-min) 997 mbar (hPa)|
A cold front exited the eastern United States on June 1 and subsequently stalled over the northwestern Atlantic Ocean. An area of low pressure formed at the tail end of the decaying front. The low tapped into moisture from the Gulf Stream and developed convection in its core. On June 5, the low transitioned into a tropical depression. Tracking northeastward, the depression quickly strengthened as it continued to draw moisture from the warm Gulf Stream. Early on June 6, the depression was upgraded to a tropical storm. Initially, Alberto was forecast to leave the Gulf Stream and turn extratropical within hours. However, the storm continued to follow the Gulf Stream northeastward, and reached peak intensity with winds of 50 mph (85 km/h) late on June 6. After leaving the Gulf Stream, Alberto rapidly weakened as it encountered colder waters, and on June 7 it degenerated into a non-convective remnant low.
|Category 1 hurricane (SSHWS)|
|Duration||July 8 – July 14|
|Peak intensity||80 mph (130 km/h) (1-min) 980 mbar (hPa)|
A low-level disturbance split from a tropical wave that was tracking across the tropical Atlantic on July 2. The disturbance traveled northwest into the central Atlantic Ocean as convection increased in its core, prompting the NHC to monitor the disturbance for possible tropical cyclogenesis. By July 7, the disturbance was producing winds of tropical storm-force but still lacked a well-defined center. Thus, the NHC began issuing advisories on a potential tropical cyclone at 20:00 UTC. A reconnaissance aircraft was able to find a well-defined closed center on July 8, and the NHC reclassified the system as Tropical Storm Beryl while the storm was located 435 miles north of Hispaniola. Beryl intensified quickly due to wind shear in the Atlantic being low. The storm turned to the northeast on July 10 as it continued to strengthen. On the same day, Beryl was upgraded to a hurricane as a ragged eye developed. Accelerating northwestward, Beryl continued to strengthen, and on July 12 reached its peak intensity with winds of 80 mph (130 km/h) while passing west of Bermuda. Shortly thereafter, Beryl entered colder waters and subsequently began weakening. The storm weakened below hurricane strength on July 13, and on July 14, Beryl had lost all tropical characteristics and was declared extratropical.
A hurricane watch was issued for Bermuda for the first time since Hurricane Nicole in the 2016 season. However, Beryl ended up passing west of the island with impacts limited to rain showers and overcast skies.
Tropical Storm Chris
|Tropical storm (SSHWS)|
|Duration||July 19 – July 23|
|Peak intensity||65 mph (100 km/h) (1-min) 995 mbar (hPa)|
- Main article: Tropical Storm Chris (2018)
A strong tropical wave moved off the coast of Africa on July 13. The NHC began to monitor the wave for possible tropical cyclogenesis. As the wave tracked across the tropical Atlantic, it developed strong convection in its center. On July 17, the NHC classified the wave as Potential Tropical Cyclone Three after a strong burst of convection occurred in the center of the disturbance. However, the potential for tropical cyclone development slowly decreased over the next day as the system struggled to develop a well-defined center. However, a reconnaissance aircraft investigating the system on July 19 confirmed the development of a well-defined center of circulation, and the NHC upgraded the system to a tropical depression. Hours later, the depression strengthened into Tropical Storm Chris. Initially a messy and disorganized storm, the overall appearance of Chris improved dramatically through July 20, with a well-defined central dense overcast accompanied by large clusters of thunderstorms developing within the system. Banding features developed within the system as it continued to intensify, and on July 21 Chris reached its peak intensity with winds of 65 mph (100 km/h) as it passed through the Leeward Islands. Afterwards, the storm gradually lost convection and weakened as wind shear strengthened significantly. On July 23, the NHC issued their last advisory on Chris as the storm degenerated into an open wave.
Shortly after the classification of Chris as a tropical depression, tropical storm watches were issued for most of the Leeward Islands. Heavy rains from the storm caused flooding and mudslides, and at least 5 fatalities were linked to the storm from a mudslide in Dominica. Overall damage was fairly minimal, at an estimated $9 million in damages and economic losses.
Tropical Storm Debby
|Tropical storm (SSHWS)|
|Duration||August 2 – August 6|
|Peak intensity||60 mph (95 km/h) (1-min) 999 mbar (hPa)|
A tropical wave exited the coast of Africa on July 31. The wave tracked northwestward over the Atlantic Ocean as it gradually organized due to favorable conditions and low wind shear. On August 2, the NHC classified the wave as a tropical depression. The following day, the depression strengthened into Tropical Storm Debby. Located over warm waters, Debby continued to gradually strengthen, and the storm's overall structure improved as a central dense overcast developed. Debby reached its peak intensity at 20:00 UTC on August 4 with winds of 60 mph (95 km/h). Shortly after reaching peak intensity, Debby encountered cooler waters and began to weaken. By August 6, the storm had weakened to a tropical depression as it accelerated northwestward. Later the same day, Debby degenerated into a non-convective remnant low, and early the next day the remnants of the storm were absorbed by an extratropical cyclone over the northern Atlantic.
Tropical Storm Ernesto
|Tropical storm (SSHWS)|
|Duration||August 11 – August 14|
|Peak intensity||45 mph (75 km/h) (1-min) 1006 mbar (hPa)|
Late on August 8, the NHC began tracking a large tropical wave and a convectively-coupled Kelvin wave over the tropical eastern Atlantic. The tropical wave interacted with the Kelvin wave on August 9, increasing convection in the former and allowing for further organization. The NHC designated the wave as a potential contender for tropical cyclone formation as enviornmental conditions improved. On August 10, the wave was classified as a potential tropical cyclone. Early the next day, a closed center of circulation developed, and the system was upgraded to Tropical Storm Ernesto at 02:00 UTC. As the storm gradually strengthened, it began to track northwest due to interacting with a trough to its south. Early on August 13, Ernesto reached its peak intensity with maximum sustained winds of 45 mph (75 km/h). Afterward, the storm's structure began to degrade as the storm began to weaken. On August 14, Ernesto degenerated into a remnant low while positioned 1,020 miles southwest of the Azores.
|Category 1 hurricane (SSHWS)|
|Duration||August 18 – August 25|
|Peak intensity||85 mph (140 km/h) (1-min) 977 mbar (hPa)|
A strong low pressure system formed northwest of the Cabo Verde islands on August 15. The following day, the NHC began tracking the system for potential development. The low continued to strengthen and organize as it tracked slowly northwestward, and on August 18 it was classified as Tropical Depression Six. Early the next day, the depression further strengthened into a tropical storm, receiving the name Florence. Strong wind shear inhibited development, and Florence weakened to a tropical depression hours after being named. By August 21, wind shear had weakened significantly, and Florence restrengthened to a tropical storm at 19:00 UTC that day. Florence also turned to the northeast due to the presence of a trough to the southwest of the storm. Early on August 23, microwave imagery revealed the presence of a low-level eye in the storm's central dense overcast, prompting the storm's upgrade to a hurricane by the NHC.
Despite entering colder waters as it continued northwestward, Florence continued to strengthen due to low wind shear, and on August 24 the storm reached its peak intensity with winds of 85 mph (140 km/h) and a minimum central pressure of 977 milibars. Afterward, the storm quickly began losing tropical characteristics as it accelerated northeastward. Florence weakened below hurricane intensity by 09:00 UTC on August 25. Six hours later, Florence transitioned into an extratropical cyclone while located 350 miles south of the Azores.
Tropical Depression Seven
|Tropical depression (SSHWS)|
|Duration||August 30 – August 31|
|Peak intensity||30 mph (45 km/h) (1-min) 1007 mbar (hPa)|
On August 27, the NHC began tracking a tropical wave that emerged off the coast of Africa for possible tropical cyclone formation. By August 29, the wave had acquired a sufficient amount of deep convection to be classified as a potential tropical cyclone. By 08:00 UTC the next day, the disturbance had developed a well-defined circulation, and it was reclassified as a tropical depression. Wind shear was expected to prevent further development, however. By August 31, a reconnaissance aircraft investigating the system was unable to locate a center of circulation, and the depression no longer classified as a tropical cyclone. At 20:00 UTC, the NHC issued its last advisories on the system, declaring it an open tropical wave.
|Category 4 hurricane (SSHWS)|
|Duration||September 3 – September 14|
|Peak intensity||140 mph (220 km/h) (1-min) 937 mbar (hPa)|
- Main article: Hurricane Gordon (2018)
A tropical wave emerged off the coast of Africa on August 31. The NHC began tracking the wave later that day, noting a high probability that it would develop into a tropical cyclone. On September 2, the wave was classified as a potential tropical cyclone, as it still lacked a well-defined center of circulation despite possessing tropical storm-force winds. The following morning, the Hurricane Hunters reported that the disturbance had developed a well-defined center, and the NHC reclassified the system as Tropical Storm Gordon. Tracking westward, Gordon strengthened under favorable conditions, reaching hurricane intensity by September 5. The next day, Gordon began to rapidly intensify, reaching major hurricane status before making landfall in the Dominican Republic. Weakening then occured as Gordon traversed the mountainous terrain in Hispaniola.
Restrengthening occured as Gordon emerged over the Atlantic Ocean. Gordon strengthened to a Category 4 hurricane as it passed through the Bahamas. On September 11, it made landfall south of Daytona Beach, Florida. The storm weakened once again as it passed over Florida, but restrengthening occurred as it entered the Gulf of Mexico. On September 12, Gordon reached its peak intensity with winds of 140 mph (220 km/h) shortly before making landfall near Pensacola, Florida. Gordon weakened quickly as it turned northeast over the Southeastern United States before losing tropical characteristics over Kentucky on September 14.
Heavy rains caused flooding and landslides that damaged many roads and buildings in the Lesser Antilles. Two deaths were attributed to a mudslide in Martinique. The storm caused extensive devastation in the Dominican Republic, where it was regarded as the worst natural disaster since Hurricane Georges in 1998. At least 298 people on the island of Hispaniola died as a result of flooding and mudslides caused by torrential rains produced by Gordon. In the Bahamas, the hurricane was the costliest since Hurricane Joaquin in 2015, inflicting nearly $170 million in damages, mainly caused by flooding due to the storm's large storm surge, measuring at 16 ft (4.9 m) in some areas.
|Category 3 hurricane (SSHWS)|
|Duration||September 12 – September 20|
|Peak intensity||115 mph (185 km/h) (1-min) 965 mbar (hPa)|
Early on September 10, the NHC began tracking a tropical wave embedded within an envelope of deep moisture as a possible contender for tropical cyclone formation. The wave quickly developed deep convection, prompting the NHC to begin issuing advisories on a potential tropical cyclone. Early on September 12, the disturbance was classified as Tropical Depression Nine. At 15:00 UTC, the depression further strengthened into Tropical Storm Helene. Favorable conditions were expected to allow Helene to strengthen, as wind shear was low and sea surface temperatures were above-normal. In the morning of September 15, Helene was upgraded to a hurricane based on a Dvorak T-number of 4.2. Helene continued to intensify as it tracked northwest, and on September 16 it briefly strengthened into a major hurricane. Afterward, Helene weakened and turned northeast after interacting with a trough. Helene weakened below hurricane strength on September 19 as it turned to the north. On September 20, Helene was declared post-tropical 135 miles northwest of the Azores.
|Category 4 hurricane (SSHWS)|
|Duration||September 13 – September 27|
|Peak intensity||150 mph (240 km/h) (1-min) 932 mbar (hPa)|
A tropical wave left the coast of Africa on September 10 and tracked slowly west-northwestward across the tropical Atlantic. Noting favorable atmospheric and oceanic conditions, the NHC gave the system a high chance of developing into a tropical cyclone. On September 12, the wave was classified as Potential Tropical Cyclone Ten, and early the next day it was reclassified as Tropical Storm Isaac. On September 15, Isaac attained hurricane strength, although it would remain a minimal hurricane for the next three days, until it rapidly intensified into a major hurricane on September 18. The storm was expected to pose a major threat to the Leeward Islands, but Isaac instead curved northeast around a ridge to its northeast. On September 19, Isaac attained an initial peak intensity of 140 mph (220 km/h) before undergoing an eyewall replacement cycle and subsequently weakening back to a Category 3 hurricane.
Late on September 20, Isaac's eyewall began to contract, signaling intensification, and on September 21 the storm reached its peak intensity with winds of 150 mph (240 km/h). Afterward, sea surface temperatures began to decrease as Isaac accelerated northeastward, causing the storm to weaken. Isaac developed the characteristics of an annular hurricane on September 23, with a large eye surrounded by a ring of deep convection, despite being located over northerly latitudes. The following day, Isaac weakened below major hurricane strength, and then below hurricane strength on September 26. On September 27, Isaac finally transitioned to a post-tropical cyclone while located 831 miles south of Greenland.
Tropical Storm Joyce
|Tropical storm (SSHWS)|
|Duration||September 21 – September 23|
|Peak intensity||45 mph (75 km/h) (1-min) 1004 mbar (hPa)|
A tropical wave emerged off the coast of Africa on September 11. Convective activity within the wave diminished as it entered a region of unfavorable conditions. On September 17, the wave entered the Caribbean Sea and merged with a mid-level trough, leading to a burst in convective activity. The NHC began to monitor the system for possible tropical cyclone development. Late on September 20, the disturbance crossed the Yucatán Peninsula, and early the next day strengthened into a tropical depression. The depression remained nearly stationary over the Bay of Campeche, and at 10:00 UTC it was upgraded to Tropical Storm Joyce. Steered westward by a ridge to its north, Joyce struggled with moderate wind shear and reached peak winds of 45 mph (75 km/h) before making landfall 10 miles south of Veracruz in Mexico. Joyce quickly weakened over the mountainous terrain of Mexico, and early on September 23 it degenerated into a remnant low.
|Category 3 hurricane (SSHWS)|
|Duration||September 29 – October 7|
|Peak intensity||120 mph (195 km/h) (1-min) 957 mbar (hPa)|
On September 27, the NHC highlighted a low pressure area associated with a tropical wave as having the potential to develop into a tropical cyclone within the following week. Unexpectedly, the low quickly organized into a tropical depression on September 29. At 22:00 UTC the same day, the depression strengthened into Tropical Storm Kirk. Steered northwestward by a ridge to its south, Kirk gradually intensified in an area favorable for development. On October 2, Kirk strengthened into a hurricane and began to rapidly intensify, reaching major hurricane status by 12:00 UTC on October 3. Turning north, Kirk executed a tight cyclonic loop on October 4 after interacting with a trough, which also caused the storm to weaken below major hurricane status. Kirk continued to track north-northeastward as it gradually weakened. Despite increasingly colder sea surface temperatures, Kirk maintained hurricane status until it transitioned to an extratropical cyclone, albeit still with hurricane-force winds. Kirk's remnants continued eastward until they were absorbed by a larger extratropical system off the coast of France.
|Category 2 hurricane (SSHWS)|
|Duration||October 11 – October 18|
|Peak intensity||110 mph (175 km/h) (1-min) 961 mbar (hPa)|
- Main article: Hurricane Leslie
A tropical wave moved off the west coast of Africa on October 6. The wave gradually strengthened, and on October 11 it organized into a tropical depression while just east of the Windward Islands. The depression strengthened into Tropical Storm Leslie early the next day. Low wind shear, combined with above-normal sea surface temperatures allowed Leslie to strengthen into a hurricane on October 14. The slow moving storm then turned northwest under the influence of a mid-level ridge to its west. Leslie began to rapidly intensify as it approached Jamaica, making landfall just below major hurricane strength on October 15. Leslie weakened significantly over the mountainous terrain of Jamaica. The storm made its second landfall in eastern Cuba as a strong tropical storm. Leslie accelerated northeast into the Atlantic Ocean and continued to weaken, and on October 18 the storm was absorbed by a frontal zone.
Upon the classification of Leslie as a tropical depression, tropical storm watches were issued for Saint Lucia and Saint Vincent and the Grenadines. No damage was reported in the Windward Islands, although rainfall amounts of up to 3.5 inches (8.89 cm) were recorded in Saint Lucia. Hurricane watches were issued for much of the Greater Antilles, including Cuba, Jamaica, and Hispaniola, shortly after Leslie was upgraded to a hurricane. In Jamaica, the watch was upgraded to a warning 18 hours before the storm's arrival, limiting preparations. Torrential rainfall in Jamaica led to widespread flooding and mudslides across the entire island. The hurricane caused 267 deaths in Jamaica, mainly from rainfall-triggered mudslides that damaged many villages in the central region of the island, and $1.57 billion in damages, making Leslie the costliest and deadliest hurricane in Jamaican history. Leslie also caused widespread flooding and mudslides in Cuba that claimed 182 lives and caused at least $3.5 billion in damages.
Tropical Storm Michael
|Tropical storm (SSHWS)|
|Duration||October 27 – October 30|
|Peak intensity||50 mph (85 km/h) (1-min) 1001 mbar (hPa)|
A cold front exited the eastern United States on October 23 and tracked swiftly across the Atlantic Ocean. The front gradually decayed, and a new low formed at the tail end of the front on October 26. The low quickly acquired tropical characteristics and detached from the front, and by October 27 it had sufficient deep convection to be classified as a tropical depression. At 06:00 UTC the following day, the depression strengthened into Tropical Storm Michael. Although ocean temperatures were relatively cool, a favorable atmospheric environment allowed Michael to strengthen, and the storm reached its peak intensity with winds of 50 mph (85 km/h) on October 29. Afterward, Michael entered a less favorable environment as it moved over colder waters. Michael finally transitioned to a post-tropical cyclone early on October 30.
Tropical Depression Fifteen
|Tropical depression (SSHWS)|
|Duration||November 3 – November 5|
|Peak intensity||35 mph (55 km/h) (1-min) 1006 mbar (hPa)|
Tropical Storm Nadine
|Tropical storm (SSHWS)|
|Duration||November 22 – November 24|
|Peak intensity||60 mph (95 km/h) (1-min) 992 mbar (hPa)|
An extratropical cyclone formed over the Central Atlantic on November 18. A small area of low pressure formed along the tail end of the cyclone on November 19. Steered by a ridge of high pressure to its northeast, the cyclone tracked southeast into warm waters. The cyclone began to acquire tropical characteristics on November 21, and by November 22 it had lost all frontal characteristics. Deep convection developed in the center of the cyclone, prompting the NHC to classify it as Subtropical Storm Nadine. By the following day, an eye feature became evident on satellite imagery as the storm's wind field contracted, signifying its transition into a tropical storm at 12:00 UTC. Six hours later, Nadine reached its peak intensity with winds of 60 mph (95 km/h). As the storm tracked northward into much colder waters, it began to weaken and lose its tropical characteristics. On November 24, with a lack of deep convection and a frontal appearance on satellite imagery, Nadine transitioned to an extratropical cyclone.
The following list of names was used for named storms that formed in the North Atlantic in 2018. The names not retired from this list were used again in the 2024 season. This is the same list used in the 2012 season, with the exception of the name Sara, which replaced Sandy.
On March 28, 2019, at the 41st session of the Regional Association Hurricane Committee, the World Meteorological Association retired the names Gordon and Leslie from its rotating name lists and they will not be used for another Atlantic hurricane again. They were replaced by Gary and Lucy, respectively, for the 2024 season.
This is a table of all the storms that formed in the 2018 Atlantic hurricane season. It includes their duration, names, affected areas, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all the damage figures are in 2018 USD.
