Atlantic hurricane seasons
2015, 2016, 2017, 2018, 2019

The 2017 Atlantic hurricane season was a moderately active season in the annual formation of tropical cyclones in the Atlantic basin that proved to be the costliest and among the deadliest on record. While only 12 storms were named, the season inflicted a preliminary damage total of over $498.5 billion in damages, over three times the cost of 2005, nearly all of which was attributed to four storms: Cleo, Eloise, Herman, and Klaus.

The season officially began on June 1, and ended on November 30, 2017. These dates historically describe the period of year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year; as seen with Tropical Depression 17, the last storm of the season which dissipated on December 6. Breaking the trend that had been seen in the previous two seasons, there was no formation of a tropical cyclone before the official start of the season. However, in mid-June, Hurricane Audrey became the second-place holder for the earliest major hurricane to develop in a season; only behind Hurricane Alma of 1966, which reached category 3 intensity on June 8. Audrey struck the state of Louisiana shortly after reaching its peak strength, becoming the first tropical cyclone to strike the state since Hurricane Isaac in 2012, and the first major hurricane to make landfall in the United States since Hurricane Wilma in 2005. A lapse in significant activity occurred until mid-August, when Hurricane Cleo became the first hurricane to make landfall at category 5 strength in the United States since Hurricane Andrew in 1992. In mid-September, Hurricane Eloise traveled thousands of miles over the Atlantic, impacting the Leeward Islands and Windward Islands before making a direct hit in Charleston, South Carolina as a category 4 hurricane, becoming the second most intense hurricane to strike the East Coast north of Florida since 1900, behind only Hurricane Hugo which made landfall slightly north of Charleston in 1989. Two weeks later, Hurricane Herman became the northernmost landfalling major hurricane on record, packing 125 mph winds as it crossed onto the New Jersey coast, causing catastrophic flooding through its 15-ft (5-m) storm surge, resulting in dozens of fatalities and hundreds of billions of dollars worth of damage. Another catastrophic flooding event took place in early November when Hurricane Klaus moved ashore in Alabama and slowed to a crawl, dumping several feet of rain as the system meandered over the area for nearly a week after landfall, setting the record for the most rainfall dropped by a tropical cyclone in the United States.

Season summary

Preseason forecasts

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 the dissipation of the 2014–16 El Niño event. On average, an Atlantic hurricane season between 1981 and 2010 contained twelve tropical storms, six hurricanes, and two major hurricanes, with an Accumulated Cyclone Energy (ACE) index of between 66 and 103 units.

Hurricane Audrey

Main article: Hurricane Audrey (2017)
Category 3 tropical cyclone (NHC)
Audrey 2017 06 23 2345Z.jpeg Audrey 2017 track revised.jpg
Duration June 19 – June 24
Intensity 185 km/h (115 mph) (1-min)
954 hPa (mbar)

In mid-June, a tropical disturbance within the Intertropical Convergence Zone (ITCZ) was first observed near Trinidad and Tobago. The disturbance later reached the Caribbean Sea and developed into a tropical depression on June 19. While heading north-northwestward, the depression intensified and was upgraded to Tropical Storm Audrey the next day. Thereafter, Audrey gradually strengthened and became a hurricane on June 21. Further strengthening continued into June 23 as Audrey neared the Gulf Coast, where it ultimately became a category 3 hurricane with peak winds of 115 mph (185 km/h) just before landfall at Grand Chenier, Louisiana shortly after midnight. The storm modestly weakened upon moving inland, falling to category 1 intensity just hours following its landfall; and later to tropical storm intensity a few hours after that. By noon on June 24, Audrey had weakened to a tropical depression and was later absorbed by a frontal system over Missouri that same evening.

The worst of the damage was confined to relatively rural sections of Louisiana and Texas coastline, with over 8 inches (203.2 mm) of rainfall and a storm surge of 12 feet (3.7 m), caused over $1.15 billion (2017 USD) in damage. A total of 237,000 people lost power, and oil rigs offshore were shut down for up to a week. 7 people were killed by the storm during its existence; all within Louisiana.

Tropical Depression Two

Duration July 6 – July 9
Intensity 65 km/h (40 mph) (1-min)
1,007 hPa (mbar)

A tropical wave emerged off the coast of Africa on June 23, and no significant development occurred until it became Tropical Depression Two in the western Gulf of Mexico on July 6. On its first advisory, a tropical storm watch was issued for from Baffin Bay, Texas southward to Tampico, Tamaulipas. Nearing the coast of Mexico, the depression attained its peak intensity with winds of 35 mph (55 km/h) and a minimum pressure of 1,007 mbar (29.7 inHg). Failing to intensify further, Tropical Depression Two made landfall near La Pesca, Tamaulipas, Mexico on July 7. The National Hurricane Center issued the final advisory on July 8, although the circulation persisted until July 9 southwest of Texas. The depression had only minor impacts in Mexico and Texas, other than rainfall. Precipitation was heaviest in San Luis Potosí, where the rainfall peaked at 12 in (304.8 mm) in Ciudad del Maíz, Mexico.

Tropical Storm Bill

Tropical storm (NHC)
Tropical Storm Bill 2017.jpg Bill 2017 track.jpg
Duration July 19 – July 24
Intensity 75 km/h (45 mph) (1-min)
1,002 hPa (mbar)

The third tropical depression of the season developed on July 19 from a tropical wave east of the Lesser Antilles. The depression slowly intensified, and was eventually upgraded to Tropical Storm Bill after it crossed Barbados late on July 21. Tropical Storm Bill crossed the Windward Islands chain, and it was noted that the storm made landfall on Saint Vincent. Emerging into the Caribbean Sea, Bill maintained tropical storm intensity through July 22 as it moved west. Wind shear began increasing over Bill, and a weakening trend began. As Bill headed further into the Caribbean Sea, it significantly weakened and was downgraded to a tropical depression on July 23. By noon on the next day, Air Force reconnaissance and satellite imagery did not show a low-level circulation, indicating that Bill had degenerated into open tropical wave 170.00 mi (273.58 km) south of Jacmel, Haiti.

Shortly before Bill was upgraded to a tropical storm, a tropical storm warning was issued for Martinique, Saint Lucia, and the Grenadines on July 21. About 24 hours later, all of the warnings were discontinued. As Bill headed further into the Caribbean Sea, tropical storm watches were issued for Hispaniola and Puerto Rico on July 22. All of the tropical storm watches and later warnings were discontinued after Bill weakened to a tropical depression. After Bill made landfall on Saint Vincent, several landslides occurred, and electrical and water services were significantly disrupted. Bill caused damage to two factories, a church, and hundreds of houses. Damage was also reported on Saint Lucia, where hundreds of buildings were damaged, electricity and telephone service was disrupted, and crops were affected as well. Wind gusts on the island of Saint Lucia reportedly reached 35 mph (56 km/h).

Hurricane Cleo

Category 5 tropical cyclone (NHC)
Cleo 2017 08 21 0735.jpg Cleo 2017.jpg
Duration August 15 – August 27
Intensity 290 km/h (180 mph) (1-min)
917 hPa (mbar)
Main article: Hurricane Cleo (2017)

A tropical wave moved off the coast of Africa on August 13, and organized into Tropical Depression Four on August 15 while located about 200 miles west of Cape Verde. It moved to the west-northwest, and strengthened into Tropical Storm Cleo on August 16. A trough of low pressure positioned to the southwest of Cleo created an environment with little vertical shear and well-defined outflow. The storm quickly intensified, and became a hurricane on August 19. It bypassed the Lesser Antilles completely, and turned west in response to a building high pressure system to the north. Cleo rapidly intensified under ideal conditions for development, and on August 21 the hurricane peaked with winds of 180 mph (290 km/h). It crossed the Bahamas at that intensity, weakened slightly, and made landfall near Homestead, Florida as a 170 mph (274 km/h) Category 5 hurricane. It weakened slightly over the state to a 130 mph (209 km/h) hurricane, but restrengthened to a 150 mph (241 km/h) hurricane over the Gulf of Mexico. Cleo crossed the Gulf throughout August 22 and 23, and curved to the north before making landfall as a 145 mph (233 km/h) category 4 hurricane in Texas after midnight on August 24. It turned northeastward, weakening as it continued further inland; degenerating to a tropical depression by the late afternoon on August 25. The storm continued to track further inland, and eventually dissipated over Quebec, Canada on August 27.

In the Bahamas, Cleo brought high tides, hurricane-force winds, and tornadoes, which caused significant damage in the archipelago, especially on Staniel Cay. At least 500 houses were destroyed and left damage to the transport, communications, water, sanitation, agriculture, and fishing sectors. Overall, Cleo caused seven fatalities and $265 million in damage in the Bahamas. Throughout the southern portions of Florida, Cleo brought very high winds; a wind gust of 182 mph (293 km/h) was reported at a house in Perrine, Florida. High winds caused catastrophic damage in Florida, especially in Miami-Dade County, where approximately 200,000 houses were either severely damaged or destroyed. In the Everglades, 70,000 acres (280 km2) of trees were knocked down and about 182 million fish were killed. Rainfall was moderate, due to the storm's fast motion, peaking at 10.28 in (261 mm) in eastern Miami-Dade County. Significant damage to oil platforms was reported, with one company losing 13 platforms, had 104 structures damaged, and five drilling wells blown off course. In Texas, Cleo produced hurricane-force winds along its path, with numerous structures being heavily damaged or destroyed, boats were tossed or capsized, power poles were bent or snapped, and trees were downed. As debris covered roadways and cellphone service was compromised, communication to the hardest-hit locales was severed. Eleven fatalities were reported in Texas. The storm spawned at least 28 tornadoes, primarily in Texas and Oklahoma. Overall, Cleo caused 64 fatalities and $68 billion (2017 USD) in damage, making it the third costliest hurricane in U.S. history, behind only Hurricane Sandy in 2012, and Hurricane Katrina in 2005.

Hurricane Diana

Category 4 tropical cyclone (NHC)
Hurricane Diana 2017.jpg Diana 2017 track.jpg
Duration August 31 – September 6
Intensity 240 km/h (150 mph) (1-min)
941 hPa (mbar)

A tropical wave moved off Africa on August 24 and failed to organize appreciably until reaching the eastern Caribbean Sea on August 28. There, an increase in convection led to the formation of a tropical depression around 06:00 UTC on August 31; it intensified into Tropical Storm Diana twenty four hours later. A broad, deep upper-level trough to the cyclone's northwest caused it to conduct a counter-clockwise turn and accelerate northeast while also aiding in the onset of a limited period of rapid intensification. Diana attained hurricane strength around 18:00 UTC on September before ultimately reaching winds of 100 mph (161 km/h), by 06:00 UTC the next day. Shortly thereafter, the hurricane made landfall in the Dominican Republic. The storm quickly tracked across the island nation, having emerged in the Atlantic as a category 1 storm twelve hours later. Diana then resumed strengthening over the open waters of the Atlantic ocean, rapidly deepening to reach its peak strength of 150 mph (241 km/h) on September 4. As the storm continued to accelerate into the colder waters of the central Atlantic, it steadily lost its strength, weakening to a tropical storm around 12:00 UTC on September 6 and degenerating to a remnant low twelve hours later. The low was absorbed by a passing extratropical cyclone later the next day.

Hurricane Eloise

Category 4 tropical cyclone (NHC)
Hurricane Eloise 2017 sep 17 0045Z.jpg Eloise 2017.jpg
Duration September 10 – September 19
Intensity 220 km/h (140 mph) (1-min)
942 hPa (mbar)
Main article: Hurricane Eloise (2017)

A westward moving tropical wave developed into Tropical Depression Six on September 10, while located southwest of Cape Verde. It headed generally westward and intensified into Tropical Storm Eloise on September 11. Eloise became a hurricane by September 13. After becoming a hurricane, rapid intensification commenced, and less than 24 hours later, Eloise was a Category 3 hurricane with winds of 120 mph (193 km/h) and a barometric pressure of 950 mbar (28.05 inHg). Eloise battered the U.S. Virgin Islands and Puerto Rico at this intensity before re-emerging into the Atlantic as a weakened category 2 hurricane on September 15. As Eloise accelerated to the northwest, re-intensification occurred, and it eventually reached a peak intensity as a low-end Category 4 hurricane. Early on September 17, Eloise made landfall near Charleston, South Carolina with winds of 140 mph (225 km/h). After landfall, Eloise rapidly weakened as it turned to the northeast, and transitioned into an extratropical cyclone by that evening. The remnants continued rapidly northeastward, and dissipated on September 19 near Greenland.

The storm caused considerable damage in Barbuda, as it contained winds of 100 mph (161 km/h). Ten fatalities and 158 injuries were reported, while 10,000 homes were destroyed, leaving 35,000 people homeless. In Antigua, one person was killed and 30% of the homes damaged. Dominica suffered the loss of 33% of its banana crop, and landslides cut off many towns for days. Five people were killed, 200 were injured, and 90% of the buildings were damaged or destroyed on Saint Thomas. About 3,500 people were left homeless. Damage estimates for Saint Thomas exceeded $3 billion. Damage from erosion and crop losses in St. Kitts reached $100 million and twelve fatalities were reported. In Puerto Rico, the storm downed thousands of trees and caused near complete destruction of coffee and damage crops. Extreme damage also occurred at Ceiba, Culebra, Fajardo, and Luquillo. Additionally, 28,000 people were left homeless, 12 deaths were reported, and losses exceeded $1 billion. In South Carolina alone, the Red Cross estimated that 5,527 single family homes were destroyed, 30,366 were inflicted major damage, and 94,554 sustained minor impact. Additionally, more than 21,056 mobile homes and 30,081 multi-family houses were either damaged or destroyed. There were 50 deaths and about $11.5 billion in damage in the state. The most significant impact elsewhere in the United States occurred in North Carolina, where 436 structures were destroyed, 2,444 suffered major damage, and 5,610 were inflicted minor impacts. There were no fatalities and damaged reached $3.5 billion. Overall, Eloise caused at least 89 fatalities and $25 billion in losses, making it the eighth-costliest hurricane in the Atlantic basin.

Tropical Storm Flora

Tropical storm (NHC)
Tropical Storm Flora.jpg Flora 2017 track.jpg
Duration September 16 – September 20
Intensity 115 km/h (70 mph) (1-min)
984 hPa (mbar)

On September 16, an area of disturbed weather associated with a broad low-pressure area off the coast of Belize organized over the warm waters of the Caribbean Sea into the seventh tropical depression of the season. Landfall in Mexico prevented significant development over the next eighteen hours as the storm crossed the Yucatán peninsula. The depression soon emerged into the Gulf of Mexico and quickly strengthened into a tropical storm on September 17. Passing over the warm, deep water of the Loop Current allowed accelerated development, and the cyclone reached its peak winds of 70 mph (115 km/h), just shy of hurricane strength. Flora continued on its northeastward track through September 18, making landfall shortly after 18:00 UTC. The storm continued onward and retained its strength until September 20: after crossing the Outer Banks of North Carolina it transitioned to an extratropical cyclone shortly after emerging into the Atlantic. The remnants meandered off the East Coast and dissipated over Nova Scotia on the evening of September 22.

Flora dropped heavy rainfall in Florida, peaking at 10.72 inches (272 mm) twelve miles northwest of Perry. In the Carolinas, fears arose that Flora would compound the damage wrought by Hurricane Eloise, which made landfall in Charleston as a category 4 hurricane just days before, sparking evacuation orders ahead of Flora's passage.

Tropical Depression Eight

Tropical depression (NHC)
TD 08.jpg Depression 08 track.jpg
Duration September 17 – September 19
Intensity 65 km/h (40 mph) (1-min)
1,006 hPa (mbar)

On September 16, a tropical wave exited Africa and quickly developed a low pressure area. Following a convective increase and better-defined outflow, it developed into Tropical Depression Eight about 232 miles (373 km) west-southwest of the southernmost Cape Verde Islands early on September 17. Because the depression was isolated from the subtropical ridge, the depression drifted west-northwestward. Westerly wind shear prevented significant development, and its peak winds were only 35 mph (56 km/h); operationally, satellite imagery suggested the storm may have reached 40 mph (64 km/h), the bare minimum for a tropical storm. By September 19, the shear and cooler waters weakened the tropical depression, which now contained a poorly defined surface center. The system lost its deep convection and by that afternoon, the depression degenerated into a remnant low. It continued west-northwestward, producing intermittent convection, until dissipating entirely east of the Lesser Antilles without redevelopment on September 24. There were no reports of damage or casualties.

Hurricane Garrett

Category 2 tropical cyclone (NHC)
Garrett 2017 09 22 0100Z.jpeg Garrett 2017.jpg
Duration September 18 – September 27
Intensity 165 km/h (105 mph) (1-min)
966 hPa (mbar)

On September 18 the ninth tropical depression of the season organized from a disturbance in the ITCZ. For the next two days the system traveled west-northwest while it strengthened into Tropical Storm Garrett. After making landfall in Eastern Venezuela, Garrett traveled westward along the South American coast as a minimal tropical storm, eventually degrading to a subtropical depression as it traversed the country. On September 23, it crossed the Gulf of Venezuela and later emerged in the Caribbean Sea, quickly regaining its tropical characteristics and reaching tropical storm strength by that evening. The storm maintained this strength until late on September 24, in which it encountered very favorable conditions and reached hurricane strength. The storm continued to strengthen into the next day, becoming a category 2 hurricane with peak winds of 105 mph (165 km/h) before making its final landfall north of Bluefields, Nicaragua. The storm gradually spun down inland, becoming a depression by September 26 before having completely dissipated the next day.

Hurricane Herman

Main article: Hurricane Herman
Category 3 tropical cyclone (NHC)
Herman 2017 10 01 0700Z.jpg Hurricane Herman revisited.jpg
Duration September 27 – October 3
Intensity 205 km/h (130 mph) (1-min)
952 hPa (mbar)

Hurricane Herman originated from a tropical wave that traversed the Atlantic uneventfully, developing into a tropical depression early on September 27 near the Bahamas. It produced an area of organized convection, and the depression intensified into Tropical Storm Herman roughly 18 hours after forming. It gradually organized over the Gulf Stream, and based on reports from the Hurricane Hunters as well as satellite observations, attained hurricane status on September 29. Shortly thereafter, the hurricane began to turn towards the north-northeast in response to a subtropical ridge over the Atlantic and the trough over the southeastern United States. After further intensification off the Florida coast, Herman reached winds of 115 mph (185 km/h) to the east of Georgia on October 1, making it a major hurricane.

Hours later, the storm underwent an eyewall replacement cycle which resulted in significant weakening, as well as a dramatic increase in the size of the storm. By the morning of October 2, Herman was back at category 2 intensity, and still intensifying. It later reached a peak intensity of 125 mph (201 km/h) as it began to undergo an extratropical transition. The cyclone was still deepening as it completed the transition at 0500 UTC on October 3, resulting in higher winds and lower pressure than the highest values observed in its tropical stages. The center of the now massive extratropical cyclone moved inland at Wildwood, New Jersey. In the Northeastern United States, damage was most severe in New Jersey and New York. Within the former, 285,000 houses were damaged or destroyed, while nearly 15,000 businesses suffered severe losses. In New York, an estimated 305,000 homes were destroyed. Severe coastal flooding occurred in New York City, with the hardest hit areas being New Dorp Beach, Red Hook, and the Rockaways; eight tunnels of the subway system were inundated. Heavy snowfall was also reported, peaking at 27 inches (686 mm) in West Virginia. Additionally, the remnants of Herman left $100 million in damage in Canada, with Ontario and Quebec being the worst impacted. Overall, 167 fatalities were attributed to Herman. Damages totaled $198 billion in the United States and $201.65 billion overall, making Herman the costliest Atlantic hurricane in recorded history, surpassing the totals of Hurricane Katrina in 2005 and other devastating systems that occurred in 2017.

A unusually well-organized disturbance moved off the African coast on December 5 and rapidly developed into Tropical Depression Seventeen. For three days a large trough of low pressure northwest of the depression steered it north-northwest towards cooler waters. Winds in the system never exceeded 35 mph (55 km/h), while moderate to heavy rain was reported along the west coast of Africa, but no damage was reported. The system eventually weakened and merged with the low pressure trough 450 miles (724 km) southwest of the Canary Islands early on December 7.

Storm names

The following list of names will be used for named storms that form in the North Atlantic in 2017. Any retired names will be announced by the World Meteorological Organization (WMO) in the spring of 2018. The names not retired from this list will not be used again until the 2023 season. This particular list has not been used in any previous season, as it was drafted by the Jarrell Meteorological Center (JMC); a independent branch of atmospheric observation and research stationed in Central Texas. Because of this, the presence of various names previously retired or recently used by the NHC appear on this list, which generated some controversy.
