Following the formation of a well-defined circulation, the disturbance was upgraded to a tropical depression at 18:00 UTC on August 12 about 265 mi (426 km) northeast of the Turks and Caicos Islands. [135], A Central American gyre and a tropical wave interacted, spawning a tropical depression about 40 mi (64 km) south of San Andrés Island on October 4. The fourteenth named storm and ninth hurricane of the hyperactive 2017 Atlantic hurricane season, Nate originated from a … [24] Activity concluded with the formation of Tropical Storm Rina in early November,[43] though the season did not officially end until November 30. [25] Despite an above average number of storms to begin 2017, many were weak and short-lived, resulting in the lowest ACE value for a season's first five named storms on record. [118] Agricultural losses alone reached about $2.85 million,[119] while infrastructural damage totaled about $407,000. Prior to affecting the U.S. mainland, Miami’s mayor Tomás Regalado noted on Hurricane Irma, "This is the time to talk about climate change. [93] In the former, about 90% of homes were damaged, with 60% of those being considered uninhabitable. 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. [25] Unlike the pattern of previous years that acted to steer many tropical cyclones harmlessly into the open Atlantic, 2017 featured a pattern conducive for landfalls;[24] in fact, the season culminated into 23 separate landfalls by Atlantic named storms. 1988 old record", "Real-Time North Atlantic Ocean Statistics by Storm for 2017", "Irma, Jose & now Maria have all accrued 40+ ACE - 1st time on record with 3 Atlantic TCs each producing 40+ ACE in a single season", "September 2017 Was the Most Active Month on Record for Atlantic Hurricanes", "Tropical Storm Arlene Forms in the Atlantic; No Threat to Land", "The current central pressure of TS #Arlene of 990 mb is the lowest pressure for any April Atlantic TC or subtropical TC on record", "Adios, Adrian: Earliest Tropical Storm in East Pacific Annals Dissipates", "Gobierno atiende a 800 familias en Miranda afectadas por tormenta Bret", Post Tropical Cyclone Report...Tropical Storm Cindy, Tropical Cyclone Report: Tropical Depression Four, Tropical Cyclone Report: Tropical Storm Don, "Gov. Five Eastern Pacific tropical cyclones made landfall in 2017. Arlene would likely not have been detected without the help of satellites, and there may well have been other similar storms this early in the year in the pre-satellite era (1966 and before). However, as shown by Tropical Storm Arlene in April, the formation of tropical cyclones was possible at other times of the year. [41] Maria was the deadliest hurricane in Dominica since the 1834 Padre Ruíz hurricane,[134] and the deadliest in Puerto Rico since the 1899 San Ciriaco hurricane. Increasing wind shear, the storm's relatively fast forward speed, and land interaction caused Bret to dissipate about three hours later. The season also had the highest accumulated cyclone energy (ACE) since 2005, with a record three hurricanes each generating an ACE of over 40: Irma, Jose, and Maria. After briefly emerging in the Caribbean Sea, Bret made another landfall on the Paria Peninsula of Venezuela around 09:00 UTC on June 20. Tropical Depression Six developed at 18:00 UTC on July 30 about 165 mi (266 km) west-northwest of St. Petersburg, Florida. In early September, Hurricane Irma became the first Category 5 hurricane to impact the northern Leeward Islands on record, later making landfall in the Florida Keys as a Category 4 hurricane. A potent extratropical cyclone formed well east of Bermuda on April 16. Late on September 8, the nascent storm peaked as a 105 mph (169 km/h) Category 2 hurricane while it began to move southwestward. Ten hurricanes occurred in succession, the greatest number of consecutive hurricanes since the start of the satellite era in 1966. The rise in the surface temperature of the ocean has had an impact on weather patterns and we must do everything possible to bring it down. After striking Barbados and Saint Vincent, Harvey entered the Caribbean Sea, where it encountered hostile wind shear. Shortly after attaining peak strength, convection began to wane and became displaced well from the center of the system, while the overall structure became comma-like in appearance on satellite imagery, signifying that Rina was transitioning into a post-tropical cyclone. Now moving north-northeastward, Nate made a second landfall near Biloxi, Mississippi, at 05:20 UTC. All Barbudans who stayed during the storm left for Antigua afterwards, leaving the island uninhabited for the first time in 300 years. [112], The interaction of a tropical wave and a mid-level trough over the Gulf of Mexico resulted in the development of Tropical Depression Thirteen on September 5, about 40 mi (65 km) east of the Tamaulipas–Veracruz state line. Initial predictions for the season anticipated that an El Niño would develop, lowering tropical cyclone activity. The Australian region season experienced the average number of cyclones reaching tropical storm intensity, numbering 11, respectively. [5] They anticipated that the 2017 season would be a near-average season, with a prediction of 14 named storms, 6 hurricanes, and 3 major hurricanes. [66] Don attained its peak intensity at this time, characterized by winds of approximately 50 mph (80 km/h) as measured by reconnaissance aircraft. The most active basin in the year was the Western Pacific, which documented 27 named systems. [14] [143] As a result, more than 360,000 electrical customers lost power due to falling trees and power lines and poles. [34] Harvey killed 108 people, including 107 in the United States[34][90] and one woman in Guyana who died after her house collapsed on her. [83] As the storm hit, severe floods occurred in Northern Ireland, with floodwaters reaching 4.9 ft (1.5 m) in height, necessitating the rescue of more than 100 people. 4 The wind speeds for this tropical cyclone are based on the Saffir Simpson Scale which uses 1-minute sustained winds. 3 (17 March 2017)", "Madagascar cyclone death toll rises to 78", "Cyclone "Cook" hits New Caledonia, leaving 1 dead, 20 000 without power", "4 killed as Cyclone Maarutha hits Irrawaddy Delta", "Cyclone Mora Wreaks Devastation Along Myanmar's West Coast, Killing One", "Sri Lanka: UN agency deploys rapid assessment teams to assist in wake of monsoon floods, landslides", "EU announces €1.5 million in assistance to victims of Cyclone Mora in Bangladesh, Myanmar", "Death toll up to 146 in Bangladesh landslides", "5 still missing, 530 displaced one month after Kyushu's deadly rain", "One dead, 20,000 evacuated as tropical storm Nanmadol batters western Japan", "Death toll from Kyushu rains hits 22 as searches, evacuations continue", "In Kyushu floods, destruction was magnified by fast-flowing driftwood", "gulftoday.ae – Tropical Storm Talas hits Vietnam, leaves one dead", "9 dead or missing in Vietnam as infrastructure is damaged – VnExpress International", "In Pics: Flood Situation in Odisha worsens, four dead", "Two killed as typhoon slams southern Japan", "Deaths reported as weakening Noru slams Japan", "Worst floods in 2 decades hit Sakon Nakhon (Updated)", "Thailand floods kill 23, cause damage estimated at $300 million", "Agricultural losses from Typhoon Nesat exceed NT$60 million – Focus Taiwan", "16 dead, 20 lakh affected in West Bengal floods", "Eight killed as heavy rains lash Jharkhand", Meteorology, Climatology, and Geophysical Agency of Indonesia, Australian Bureau of Meteorology (TCWC's Perth, Darwin & Brisbane), Papua New Guinea National Weather Service, Meteorological Service of New Zealand Limited, https://en.wikipedia.org/w/index.php?title=Tropical_cyclones_in_2017&oldid=995757628, Articles needing additional references from December 2020, All articles needing additional references, Articles to be expanded from November 2020, Wikipedia articles incorporating text from the National Weather Service, Creative Commons Attribution-ShareAlike License, Philippines, Taiwan, South China, Vietnam, Philippines, South China, Vietnam, Thailand. They also predicted an ACE index of around 101 units. [110] Damage in the state reached approximately $337,000. [146], The storm produced heavy rainfall in the Cayman Islands, Cuba, Florida, and the Bahamas. Although well offshore, winds from Ophelia fanned wildfires in Portugal and Spain. Tropical Storm Cindy was the first tropical cyclone to make landfall in Louisiana since Hurricane Isaac in 2012. Hurricane-force winds extend outward up to 60 miles (95 km) mainly to the west of the center, and tropical-storm-force … IMAGE COURTESY OF CIRA AND RAMMB. The storm briefly weakened to a Category 4 by the time it reached the Caribbean, but re-strengthened to a Category 5 hurricane later on September 19. Operationally, Philippe was assessed as crossing the Florida Keys and exiting into the western Atlantic, but post-analysis showed that it was a non-tropical area of low pressure that was interacting with Philippe. Scientists pointed out that the increase of CO2 emissions contributes to warmer ocean waters and more moist air for rain. Because the cyclone had an asymmetrical structure, heavy rainfall was observed over southeastern Mississippi, southwestern Alabama, and the far western Florida Panhandle, while lesser precipitation amounts fell over Louisiana and Texas. The measure is calculated at full advisories for cyclones at tropical storm strength—storms with winds in excess of 39 mph (63 km/h). Regardless, some outlets such as the Associated Press "poked fun" at the name and Trump. Damage totaled about $500 million. As it started on a northerly track, Rina continued to strengthen despite strong shear and dry air intrusion, and also began to show subtropical characteristics marked by most of the deep convection and strongest winds well removed from the center. Max Mayfield, former director of the NHC, clarified that the name had no relation to Trump and was chosen in 2006 as a replacement for Dennis. With precipitation peaking at 4.76 in (121 mm) in Penal, several towns in southern and central Trinidad were flooded. In the United States Virgin Islands (USVI), widespread destruction was reported on Saint Thomas, Saint John, and Saint Croix. Gradually, the system became better organized and was able to maintain an area of deep convection to the east of the center. [34] Rockport, Fulton, and the surrounding cities were particularly hard hit. [29] Above-average activity continued throughout June and July with the formations of tropical storms (and a depression) Bret, Cindy, Four, Don, and Emily; however, a majority of these storms were weak and short-lived. However, by September 15, convective activity increased and became more organized, including the development of curved cloud bands. Located in an area of weak steering currents, the cyclone meandered around in the region and strengthened into Tropical Storm Katia at 06:00 UTC on September 6. [4], The first forecast for the year was issued by TSR on December 13, 2016. Bret intensified slightly further, peaking with maximum sustained winds of 50 mph (80 km/h) around 02:00 UTC the following day. [24], September featured copious activity, with four hurricanes forming: Jose, Katia, Lee, and Maria,[37] the final of which became the tenth-most-intense Atlantic hurricane on record. As Lee moved northwest in tandem with an upper-level trough with periodic bursts of convection, wind shear decreased slightly, allowing Lee to reintensify to a tropical storm again early on September 19 and attaining an initial peak intensity with winds of 45 mph (72 km/h) that day. [131] By the end of January 2018, only about 65% of electricity on the island had been restored. Precipitation peaked at 60.58 in (1,539 mm) in Nederland—the highest-ever rainfall total for any tropical cyclone in the United States. [128] An eyewall replacement cycle that night led to the emergence of a larger eye surrounded by cold cloud tops, and by 12:00 UTC on September 27, Lee reached its peak intensity as a Category 3 hurricane with winds of 115 mph (185 km/h). Around 22:00 UTC on October 28, the storm made landfall on the Zapata Peninsula with winds of 40 mph. (National Hurricane Center) At a Glance. Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes, and major hurricanes will form during a season, and/or how many tropical cyclones will affect a particular country. On the East Pacific, a weak depression, Tropical Storm Jova, Hurricane Kenneth and another tropical storm, Tropical Storm Lidia (2017) formed. Reaching a forward speed of 29 mph (47 km/h), Nate became the fastest-moving tropical cyclone ever recorded in the Gulf of Mexico. [142], Around 12:00 UTC on October 14, Ophelia strengthened into a Category 3 hurricane and peaked with maximum sustained winds of 115 mph (185 km/h) and a minimum barometric pressure of 959 mbar (28.3 inHg), becoming the easternmost major hurricane in the Atlantic basin on record. [142] Five deaths occurred, two from trees falling onto cars and three related to cleanup and repair work in the storm's aftermath. 23 systems formed on the month of July, making it the busiest month of this year. Weakening quickly ensued, and later that day the circulation of Emily became elongated as it was downgraded to a tropical depression.

The system weakened to a tropical depression over central Louisiana later that day, before losing tropical characteristics over central Tennessee early on September 1. Figure 3. However, coastal flooding mainly consisted of roads being inundated, while some beach erosion occurred. At 06:00 UTC on August 15, Gert intensified into a Category 1 hurricane. The disturbance became Tropical Storm Franklin at 00:00 UTC on August 7, about 85 mi (137 km) north-northeast of Cabo Gracias a Dios. In February, 16 systems formed. A reconnaissance aircraft investigating the system east of the Caribbean on September 5 found the cyclone at Category 5 intensity. The birth of Harvey occurred on Sunday August 13 th, 2017 as a tropical wave emerged off the west coast of Africa, eventually merging with a broad area of low pressure near the Cabo Verde Islands. [10] On May 25, NOAA released their prediction, citing a 70% chance of an above average season due to "a weak or nonexistent El Niño", calling for 11–17 named storms, 5–9 hurricanes, and 2–4 major hurricanes. The strongest tropical cyclone was Hurricane Maria with a minimum barometric pressure of 908 mbar (hPa; 26.81 inHg). [115] Tourists left coastal towns, emergency shelters were opened, and storm drains were cleared before the onset of heavy rainfall. Shortly thereafter, the storm intensified into a hurricane. The storm almost entirely destroyed the island's banana crop. In late August, Hurricane Harvey struck Texas and became the first major hurricane to make landfall in the United States since Wilma in 2005 and the strongest since Charley in 2004. In Trinidad, the storm produced sustained winds of 48 mph (77 km/h) and gusts up to 71 mph (114 km/h) at Guayaguayare. [120] Coincidentally, the storm struck Mexico just days after a major earthquake struck the country, worsening the aftermath and recovery. [34], The hurricane made landfall in Texas between Port Aransas and Port O'Connor around 03:00 UTC on August 26, possessing maximum winds of 130 mph (210 km/h). Over the next few months, these anomalies warmed and nearly reached the thresholds needed for an El Niño event to be declared, however, they subsequently cooled throughout the rest of the year and the 2017–18 La Niña event was declared to be underway. About 25 homes on the western end of Dauphin Island suffered severe damage from storm surge flooding, while several other homes experienced minor damage. Additionally, they predicted a revised ACE index of 116 units. Storm surge and abnormally high tides inundated coastal roads and damaged or destroyed hundreds of piers. The storm tracked into the cold sector of the cyclone, causing Arlene to lose tropical characteristics around 12:00 UTC on April 21. Continuing north-northeastward, the extratropical low eventually turned east-northeastward over the Mid-Atlantic and dissipated near Newfoundland on October 11. The storm steadily weakened over the southeastern United States before losing tropical characteristics in Georgia early on September 12. Irma resulted in at least 92 deaths in the United States. Harvey updated 09 May 2018; This document provides a summary of warnings issued for a Potential Tropical Cyclone. At a Glance. Potential tropical cyclones are not included in this table.
