2017 Hurricane Season Storm Timeline

2017 Season Milestones

  • The 2017 Atlantic Hurricane Season was active, deadly, and extremely destructive. The Season had 17 named storms, the fifth-most active season since records began, equalling 1936. (Records began in 1851)
  • The season also featured both the highest total accumulated cyclone energy (ACE) and the highest number of major hurricanes since 2005.
  • All ten of the Season's Hurricanes occurred in a row, the greatest number of consecutive hurricanes in the satellite era, and tied for the greatest number of consecutive Hurricanes ever observed in the Atlantic basin.
  • 2017 was by far the costliest Hurricane Season on record, with a preliminary total of approximately $281.14 billion (USD) in damages, or about $100 billion higher than the total of the 2005 season. In addition, essentially all of the season's damage was due to three of the Season's Major Hurricanes — Harvey, Irma, and Maria.
  • Tropical Storm Arlene formed in April. Hurricane Season officially begins on June 1 and ends on November 30. These dates historically describe the period of year tropical cyclones are most likely to form in the Atlantic basin.
  • In mid-June, Tropical Storm Bret struck the island of Trinidad, which is rarely experiences tropical cyclones due to its very low latitude.
  • In late August, Hurricane Harvey became the first major hurricane to make landfall in the United States since Wilma in 2005.
  • Hurricane Harvey was the costliest tropical cyclone on record.
  • Hurricane Harvey dumped the most rainfall dropped by a tropical cyclone in the United States since records began.
  • In early September, Hurricane Irma became the first Category 5 hurricane on record to impact the northern Leeward Islands, later making landfall in the Florida Keys as a large Category 4 hurricane.
  • In terms of maximum sustained winds, Irma had the highest maximum sustained winds ever recorded in a hurricane in the Atlantic Ocean (outside of the Gulf of Mexico and Caribbean Sea.)
  • In late September, Hurricane Maria became the first Category 5 hurricane on record to strike the island of Dominica. It later made landfall in Puerto Rico as a high-end Category 4 hurricane.
  • In early October, Hurricane Nate became the fastest-moving tropical cyclone in the Gulf of Mexico. Nate was also the fourth hurricane of the year to hit the overall United States.
  • Hurricane Ophelia became the eastern-most Major Hurricane on record in the Atlantic basin, and impacted most of Northern Europe as an extra-tropical cyclone.

    Tropical Storm Arline's origins were non-tropical. A large and strong extratropical low developed about 750 n mi east of Bermuda early on 16 April.

    There were no reports of damage or casualties associated with Arline.

    Tropical Storm Bret formed southeast of Trinidad and affected portions of the southern Windward Islands and the Paria Peninsula of Venezuela before dissipating over the southeastern Caribbean Sea. Bret marked the earliest formation of a named storm during the season in the Atlantic basin's main development region (south of 20°N and east of 70°W).

    According to media reports, one indirect death from Bret occurred in Trinidad, where a man fell to his death after slipping on a makeshift bridge while running through heavy rains. Roof damage was reported to nearly 100 homes in Trinidad, along with some downed utility poles and power outages. Flooding was noted in several towns in southern and central Trinidad, with flood waters rising as high as 13 feet outside of homes in Lower Barrackpore. In Venezuela, two people were injured on Margarita Island due to a collapsed wall, and mudslides damaged and destroyed numerous homes on the island. Several boats were damaged and some flooding was also noted on the island. On Grenada, only minor damage and some power outages were reported.

    Tropical Storm Cindy was a large, sprawling tropical storm that formed in the Gulf of Mexico and made landfall just east of the Louisiana-Texas border. Cindy produced heavy rainfall and river flooding, as well as some coastal flooding, over the northern Gulf coastal region. The storm caused one direct death in Alabama

    Cindy caused one direct death as a result of waves along the coast. A 10-year-old boy died after he was struck by a log pushed onshore by a large wave outside his family's condominium in Fort Morgan, Alabama. A 57-year-old man also died in Fort Morgan when he drowned in a rip current while attempting to rescue two children. However, the drowning occurred after Cindy had become a remnant low while centered over the Tennessee Valley. Two children were injured when a tree fell on their mobile home in Terrebonne Parish, Louisiana.

    Tropical Storm Don was the third short-lived tropical cyclone to form in the deep Tropics early in the 2017 Atlantic hurricane season. It reached an intensity of 45 kt before decaying into a wave as it approached the Windward Islands.

    There were no reports of damage or casualties associated with Don.

    Tropical Storm Emily made landfall on Anna Maria Island around 0854 local time on 31 July. Weakening quickly ensued, and later that day the circulation of Emily became elongated as it was downgraded to a tropical depression.

    On August 1, torrential rains related to Emily impacted parts of Miami Beach, with accumulations reaching 6.97 in (177 mm) in 3.5 hours, of which 2.17 in (55 mm) fell in just 30 minutes. Coinciding with high tide the deluge overwhelmed flood pumps, with three of them shutting down due to lightning-induced power outages, and resulted in significant flash floods. Multiple buildings suffered water damage, with some having 2.5 ft (0.76 m) of standing water. One person was hospitalized after becoming stuck in flood waters. Portions of Downtown Miami, such as Brickell, were also heavily affected; numerous vehicles became stranded in flooded roadways. Total damages from Emily are estimated to be less than US$10 million.

    Hurricane Franklin made landfall just North of the Belize Mexican border, causing few id any problems. After re-emerging into the Bay of Campeche the storm immediately began strengthening again, and became a hurricane late on August 9. Five hours after peaking in intensity with winds of 85 mph (140 km/h) and a pressure of 981 mbar (28.97 inHg), Franklin made landfall near Lechuguillas, Mexico, and began to rapidly weaken.

    There were no reports of damage or casualties associated with Hurricane Franklin.

    Hurricane Gert intensified into a Tropical Storm 03:00 UTC on August 15, Gert intensified to a Category 1 hurricane with maximum sustained winds of 75 mph. Accelerating east-northeastwards, Gert peaked as a Category 2 system early on August 17 at an unusually high latitude of 40°N.[109] Thereafter, Gert began to rapidly weaken as it shifted from the Gulf Stream over cooler waters.[110] Just 12 hours after achieving peak intensity, Gert weakened below hurricane status and evolved to an extratropical cyclone well east of Nova Scotia.

    Two people drowned due to strong rip currents produced by the hurricane: one in the Outer Banks of North Carolina, and the other in Nantucket, Massachusetts. No damage associated with Gert was reported.

    Major Hurricane Harvey: Harvey started as a typical weak August tropical storm that affected the Lesser Antilles and dissipated over the central Caribbean Sea. However, after re-forming over the Bay of Campeche, Harvey rapidly intensified into a category 4 hurricane (on the Saffir Simpson Hurricane Wind Scale) before making landfall along the middle Texas coast. The storm then stalled, with its center over or near the Texas coast for four days, dropping historic amounts of rainfall of more than 60 inches over southeastern Texas. These rains caused catastrophic flooding.

    Harvey is responsible for at least 68 direct deaths in the United States, all in Texas. Over half of the deaths (36) were in Harris County in the Houston metro area. A county-by-county listing of the direct deaths is available in Table 4. All but three of the deaths were from freshwater flooding, and none of the deaths can be linked to the storm surge, which is quite remarkable for a category 4 hurricane landfall. Still, Harvey is the deadliest U.S. hurricane in terms of direct deaths since Sandy (2012) and is the deadliest hurricane to hit Texas since 1919. About 35 additional deaths are ascribed to indirect causes, such as electrocution, motor-vehicle crashes and isolation from necessary medical services. Four people were reported injured by a tornado north of Reform, Alabama.

    Major Hurricane Irma: Irma was a long-lived Cape Verde hurricane that reached category 5 intensity on the Saffir-Simpson Hurricane Wind Scale. The catastrophic hurricane made seven landfalls, four of which occurred as a category 5 hurricane across the northern Caribbean Islands. Irma made landfall as a category 4 hurricane in the Florida Keys and struck southwestern Florida at category 3 intensity. Irma caused widespread devastation across the affected areas and was one of the strongest and costliest hurricanes on record in the Atlantic basin.

    Irma caused 44 direct deaths3 as a result of its strong winds, heavy rains, and high surf across the Caribbean Islands and the southeastern United States. The majority of the causalities were in the Caribbean Islands, where Irma’s winds were the strongest. Eleven direct deaths were reported combined in Saint Martin and Saint Barthelemy, 9 in Cuba, 4 in Sint Maarten, 4 in the British Virgin Islands, 3 in the U.S. Virgin Islands, 3 in Barbuda, 1 in Barbados, 1 in Haiti, and 1 in Anguilla.

    In the United States, 7 direct deaths were reported, and an additional 85 indirect deaths occurred, 80 of which were in Florida. Hundreds more were injured before, during, or after the hurricane. About 6 million residents in Florida were evacuated from coastal areas.

    Major Hurricane Jose: Jose was a classic, long-lived Cape Verde hurricane that reached category 4 strength (on the Saffir-Simpson Hurricane Wind Scale) east of the Leeward Islands but fortunately spared the Irma-ravaged islands of the northeastern Caribbean Sea. Jose made a clockwise loop over the southwestern Atlantic, and it then meandered off the coast of New England as a tropical storm for several days. Jose produced tropical-storm-force winds, as well as minor coastal flooding, along portions of the mid-Atlantic and southern New England coastline.

    There were no reports of casualties associated with Jose. After Hurricane Irma had hit Barbuda on 6 September, destroying about 95% of the infrastructure and leaving more than half of the island’s residents homeless, the government of Antigua and Barbuda issued a mandatory evacuation of Barbuda two days later, on 8 September, due to the threat posed by Jose. Media reports indicated that about 1700 people were evacuated to Antigua, leaving Barbuda uninhabited for the first time in 300 years. In the northeastern United States, damage was primarily limited to numerous trees and electrical lines being downed by strong winds in portions of southeastern Massachusetts and Rhode Island. On Nantucket, four sailboats sank in Nantucket Harbor, primarily due to heavy rainfall, and four other boats washed ashore. Minor-to-moderate coastal flooding and moderate beach erosion occurred along portions of the coast from North Carolina to Massachusetts.

    Hurricane Katia was a category 2 hurricane (on the Saffir-Simpson Hurricane Wind Scale) over the extreme southwestern Gulf of Mexico. It weakened and made landfall near Tecolutla, Mexico, as a category 1 hurricane.

    According to Mexican authorities, rains from Hurricane Katia caused a mudslide that left two people dead in Xalapa, the capital of the state of Vera Cruz. There were reports of widespread power failures and many mudslides, but the hurricane did not appear to cause any major damage in the region.

    Major Hurricane Lee: Lee was a long-lived cyclone that began as a weak storm over the far eastern tropical Atlantic. It dissipated without much fanfare several days after formation, but regenerated over the subtropical Atlantic as a result of a trough interaction. After becoming trapped under a mid-latitude ridge and performing a sharp cusp, the small storm turned westsouthwestward, eventually becoming a larger category 3 hurricane (on the Saffir-Simpson Hurricane Wind Scale) before recurving well east of Bermuda.

    There were no deaths or damage attributable to Lee.

    Major Hurricane Maria: Maria was a very severe Cape Verde Hurricane that ravaged the island of Dominica at category 5 (on the Saffir-Simpson Hurricane Wind Scale) intensity, and later devastated Puerto Rico as a high-end category 4 hurricane. It also inflicted serious damage on some of the other islands of the northeastern Caribbean Sea. Maria is the third costliest hurricane in United States history

    Maria was a deadly and catastrophic storm. Details of the damage and casualties can be found in the Tropical Cyclone Report linked linked below.

    Hurricane Nate: Nate crossed northeastern Nicaragua and eastern Honduras as a tropical storm, then made landfall on the northern Gulf Coast as a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. Combined with a strong Central American gyre in the Pacific Inter-tropical Convergence Zone rains associated with Nate caused significant impacts in Central America a from 3–7 October.

    The widespread heavy rains over Central America produced widespread flooding and mudslides, and media reports indicate that these caused 44 deaths in the region: 16 in Nicaragua, 13 in Costa Rica, 6 in Panama, 5 in Guatemala, 3 in Honduras, and 1 in El Salvador. An additional death in Panama was due to a “shipwreck”, bringing the death toll directly associated with Nate to 45. An additional 9 people were missing in the region. No deaths were directly associated with Nate in the United States. However, there were two fatalities indirectly related to the storm due to traffic accidents. Media reports indicate that the flooding and mudslides in Central America damaged or destroyed thousands of homes, with Costa Rica and Nicaragua reporting the greatest damage. There was also significant damage to agriculture and the transportation infrastructure in the region, with the Instituto Meteorológico Nacional of Costa Rica reporting a total of $562 million in damage. The locally heavy rains that occurred in the Cayman Islands and western Cuba, apparently produced only minor damage in these areas. In the United States, the National Centers for Environmental Information reported that a combination of winds, storm surge, freshwater flooding, and tornadoes caused $225 million damage to property and agriculture.

    Major Hurricane Ophelia: Ophelia was a category 3 hurricane (on the Saffir-Simpson Hurricane Wind Scale) that spent its entire lifetime over the far eastern Atlantic Ocean, becoming the farthest-east major hurricane observed in the satellite era. After becoming a post-tropical/extratropical cyclone, Ophelia produced hurricane-force wind gusts over much of Ireland and the United Kingdom, resulting in considerable property damage and loss of life. Extratropical Ophelia was the worst storm to affect Ireland in 50 years.

    There were no reports of casualties associated with Ophelia while it was a tropical cyclone. However, three deaths occurred in Ireland during Ophelia’s extratropical phase. Media reports indicate that a woman in her 70 was killed after a tree fell on her car in Waterford in the southeastern portion of the country, a man in his 30s was killed during a chain saw accident while clearing a fallen tree in Tipperary County, and another man died in Louth near Dublin after his car was struck by a tree.
