Part of the 2017 Atlantic hurricane and 2017–18 European windstorm seasons |
Hurricane Ophelia (known as Storm Ophelia in Ireland and the United Kingdom while extratropical) was regarded as the worst storm to affect Ireland in 50 years,and was also the easternmost Atlantic major hurricane [nb 1] on record. [2] The tenth and final consecutive hurricane and the sixth major hurricane of the very active 2017 Atlantic hurricane season,Ophelia had non-tropical origins from a decaying cold front on 6 October. Located within a favorable environment,the storm steadily strengthened over the next two days,drifting north and then southeastwards before becoming a hurricane on 11 October. After becoming a Category 2 hurricane and fluctuating in intensity for a day,Ophelia intensified into a major hurricane on 14 October south of the Azores,brushing the archipelago with high winds and heavy rainfall. Shortly after achieving peak intensity,Ophelia began weakening as it accelerated over progressively colder waters to its northeast towards Ireland and Great Britain. Completing an extratropical transition early on 16 October,Ophelia became the second storm of the 2017–18 European windstorm season. Early on 17 October,the cyclone crossed the North Sea and struck western Norway,with wind gusts up to 70 kilometres per hour (43 mph) in Rogaland county,before weakening during the evening of 17 October. The system then moved across Scandinavia,before dissipating over Norway on the next day.
Three deaths can be directly attributed to Ophelia,all of which occurred in Ireland. Total losses from the storm were less than initially feared,with a minimum estimate of total insured losses across Ireland and the United Kingdom of US$87.7 million.
On 3 October, a broad low-pressure area had formed along a stationary front about 460 mi (740 km) west of the Azores. The low meandered over the north Atlantic for days. On 6 October, a large wind field had formed associated with the low. The low only developed shallow, weak convection, along with a long, curved cloud band, and a cold-core center—typical characteristics of an extratropical low. [3] The system began to acquire subtropical characteristics on the next day, benefits from warm sea surface temperature of 81 °F (27 °C), thus the National Hurricane Center (NHC) noted for a high chance of tropical cyclogenesis. [4] Although the system lost some of its organization due to dry mid-level air, [5] it managed to develop gale-force winds and a well-defined center. [6] Deep convection continued to develop near the center early on 9 October, [7] and the NHC classified the system as Tropical Storm Ophelia at 06:00 UTC, about 875 mi (1,410 km) west-southwest of the Azores. [3]
Despite moving over marginally warm waters of 79.7 °F (26.5 °C), the effects of cold air temperatures aloft and decreasing wind shear allowed Ophelia to gradually strengthen. At the same time, Ophelia drifted several hundred miles southwest of the Azores due to the cut off from mid-latitude westerlies. [8] In addition, the large temperature contrast between the unusually-warm ocean surface and the extremely cold temperatures in the upper atmosphere provided instability for Ophelia's thunderstorms, which allowed the storm to continue strengthening, despite marginally warm ocean temperatures. [3] [9] Late on 10 October, Ophelia began to move southeastwards as it embedded in a mid-to upper-level trough. [10] A slight degradation of the structure of the storm resulted in some weakening early on 11 October, [11] but this was short-lived as deep convection wrapped around the entire storm. [12] After developing a ragged eye, [13] the NHC upgraded Ophelia to a hurricane at 18:00 UTC about 760 mi (1,225 km) south of the Azores. [3] Upon the upgrade, Ophelia becoming the record-tying tenth consecutive hurricane to form during the 2017 hurricane season; this was the fourth such occurrence after 1878, 1886, and 1893 seasons. [14] [nb 2] Afterwards, Ophelia steadily intensified as it became nearly stationary, intensifying to a Category 2 hurricane late on 12 October, as the eye became better defined. [15] Ophelia achieved its initial peak intensity at 06:00 UTC on 13 October, with maximum sustained winds of 105 mph (169 km/h) and a central pressure of 966 mbar (966 hPa; 28.5 inHg). [3]
The hurricane accelerated to the northeast, under the influence of the large mid-latitude trough. [16] Ophelia weakened slightly later that day. The cloud tops warmed due to moderate vertical wind shear, [17] but wind shear decreased shortly afterwards, allowed Ophelia to strengthen once again. [18] Its eye became better defined, and the NHC upgraded Ophelia to a Category 3 hurricane at 12:00 UTC on 14 October; at 27.7°W, this was the farthest east that a storm of such intensity had been observed in the satellite era. [19] It attained its peak intensity simultaneously with maximum sustained winds of 115 mph (185 km/h) and a central pressure of 959 mbar (959 hPa; 28.3 inHg) while located approximately 575 mi (925 km) southwest of the Azores. [3] Early on 15 October, increasing wind shear and cold waters of 68 °F (20 °C) caused Ophelia to gradually weaken. Embedded within a fast southwesterly flow, Ophelia raced to the north-northeast with a speed of 38 mph (61 km/h). [20] After losing all of its deep convection and becoming attached to a warm front and a cold front, [21] the storm became extratropical at 00:00 UTC on the next day, about 310 mi (500 km) southwest of Mizen Head. The extratropical low then made landfall in southwestern Ireland, near Valentia Island, with winds of 75 mph (121 km/h), at 11:00 UTC. Afterwards, Ophelia's extratropical remnants tracked over Ireland and made its second landfall in Soay, Inner Hebrides with winds of 60 mph (97 km/h), at 23:45 UTC. On 17 October, the extratropical low turned to the east-northeast, and tracked over the North Sea. The storm made its third and final landfall in Våge, Austevoll, with winds of 45 mph (72 km/h), at 17:30 UTC, before dissipating over Norway early on 18 October. [3]
The Portuguese Institute of the Sea and the Atmosphere issued a red warning for heavy rainfall for the eastern group of the Azores—São Miguel, Santa Maria and Formigas—on 14 October from 17:59 UTC to 23:59 UTC. [22] An orange gale warning was issued for the eastern group for the afternoon through night of 14–15 October, [22] as well as a yellow alert for high seas. [22] Rainfall alerts were also issued for the central group—Terceira, Graciosa, São Jorge Island, Pico and Faial.
The President of the Regional Service of Civil Protection of the Azores, Lieutenant-Colonel Carlos Neves, announced there was no serious damage. High winds downed four trees on São Miguel, three in the Ponta Delgada district and one in Povoação. The island also experienced some minor flooding. In the central group of the Azores, there were a few instances of light damage, with one home suffering a roof leak. [23]
Starting on 15 October 2017, winds from Ophelia fanned wildfires in both Portugal and Spain. The wildfires have claimed the lives of at least 49 individuals, including 45 in Portugal and four in Spain, and dozens more were injured. [24] [25] [26] [27] [28] In Portugal, more than 4,000 firefighters battled around 150 fires. [29] The National Hurricane Center's Tropical Cyclone Report on Hurricane Ophelia makes no mention of the fires, thus the associated fatalities are not included as part of the storm total. [3]
Met Éireann, Ireland's national meteorological service, reported on 12 October that the storm would reach Ireland. On 14 October, it issued a 'Status Red' warning, its highest storm category, [30] for portions of Ireland. [31] [32] Issuing such a warning more than 48 hours in advance was "unprecedented," as such warnings are normally issued within 24 hours of the event. [33] On 15 October, the National Emergency Coordination Centre and Met Éireann convened to advise the public in relation to the post-tropical storm reaching Ireland. At 20:15 on the 15th, 'status red' was extended to all of Ireland, [33] and all public education services were confirmed as cancelled. [34]
The Department of Education confirmed that all Montessoris, crèches, primary and post-primary schools would be closed on 16 and 17 October. [35] [36] Other public services would be withdrawn such as Court and District Court services, third-level institutes such as UCC, CIT, University of Limerick, and Waterford Institute of Technology. [37] Aer Lingus confirmed a number of flights from Cork Airport and Shannon Airport would be cancelled, with the likelihood of 50 flights being cancelled. [38] All public transport previously scheduled within the red alert zone were cancelled including bus, rail and ferry journeys. Bus Éireann announced the cancellation of school bus services for the west of Ireland after Met Éireann issued a rare Status Red warning affecting the south western and western counties of Wexford, Waterford, Cork, Kerry, Clare, Mayo and Galway. [39] The Department of Housing, Planning and Local Government confirmed members of the public should not make any unnecessary journeys especially travelling within the red level warning areas and the department reiterated the storm's potential risk to life. [40]
On 16 October, gusts of up to 191 km/h (119 mph) were recorded at Fastnet Rock off the coast of County Cork, the highest wind speeds ever recorded in Ireland. 10-minute sustained wind speeds at Roches Point, also in County Cork, reached 111 km/h (69 mph), with gusts of 156 km/h (97 mph). [41]
ESB Group confirmed that more than 360,000 customers were without power in the wake of the storm. [42] [43] Two people, a man in Dundalk and a woman in Aglish, County Waterford, were killed when trees fell on their cars. [44] [45] In County Tipperary, another fatality occurred when a man was clearing a fallen tree with a chainsaw. [46] Two men died in separate incidents after suffering fatal injuries while carrying out repairs to damage caused by Ophelia and Storm Brian. In Cork, a man died after he fell while working on a shed roof, and in County Wicklow another man died after falling from a ladder while carrying out repairs to his farm shed. [47] Initially, it was estimated that Ophelia would cause €1.5 billion (US$1.8 billion) worth of losses in Ireland, mostly due to the shutdown of economic activities on the day of its passage. [48] However, as of 24 October, insurance claims across the country just reached €50 million (US$59 million), much less than the initial estimation of damage. [49] Total damage across the country stood at €68.7 million (US$81.1 million). [50]
The Met Office in the United Kingdom issued the first severe weather warnings for Ophelia on 12 October, referring to the hurricane as "ex-Ophelia" in the context of the 2017–18 UK and Ireland windstorm season. [51] The severe weather warning initially issued on 12 October was a yellow weather warning for wind, covering Northern Ireland, western England, Wales, and southern and western Scotland, valid between 12:00 and 23:55 BST on 15 October. [51] The weather warning impact matrix warned of relatively severe impacts anticipated, although with a low level of certainty so far in advance preventing the issuance of amber weather warnings initially. [51] Subsequently, on 13 October, a yellow severe weather warning for wind was issued for Northern Ireland, southern Scotland, western England and Wales, valid between 00:05 and 15:00 BST on 17 October. The weather warning for wind in Northern Ireland on 15 October was upgraded to an amber.
The arrival of Ophelia brought Saharan dust to parts of the United Kingdom, giving the sky an orange or yellow-sepia appearance, and the sun a red or orange appearance. [52] [53] A strange 'burning' smell was also reported across Devon, also attributed to the dust, and smoke from forest fires in Portugal and Spain. [54] Winds up to 115 km/h (71 mph) were observed in Orlock Head, County Down, at the height of the storm. Approximately 50,000 households lost power in Northern Ireland. Insurance claims from Northern Ireland, Wales, and Scotland are estimated to reach £5–10 million (US$6.6–13.3 million). [55]
In Tallinn, Estonia, black rain fell because Ophelia brought smoke and the soot of fires to Estonia from Portugal, as well as dust from the Sahara Desert, Report informs citing the Estonian media. "We looked at photos from satellites and the Finnish weather service confirmed that the smoke and soot of the fires in Portugal and partly the dust from the Sahara reached us," meteorologist Taimi Paljak said. [56] [57]
Climate scientist Reindert Haarsma of the Royal Netherlands Meteorological Institute said that climate change is likely to cause Europe to see more hurricanes like Ophelia, as the oceans get warmer, although they were still comparing their model's results (previously reported in 2013) with those from other climate centres. [58] But UCD Professors Ray Bates and Ray McGrath argued that "insofar as the influence of the sea surface temperature is concerned, the exceptional strength of Storm Ophelia was due to natural variability" rather than global warming. [59]
Tropical Storm Ana was the first named storm of the 2003 Atlantic hurricane season. A pre-season storm, it developed initially as a subtropical cyclone from a non-tropical low on April 20 to the west of Bermuda. It tracked east-southeastward and organized, and on April 21 it transitioned into a tropical cyclone with peak winds of 60 mph (97 km/h). Tropical Storm Ana turned east-northeastward, steadily weakening due to wind shear and an approaching cold front, and on April 24 it became an extratropical cyclone. The storm brushed Bermuda with light rain, and its remnants produced precipitation in the Azores and the United Kingdom. Swells generated by the storm capsized a boat along the Florida coastline, causing two fatalities.
Hurricane Gordon was the first tropical cyclone since 1992 to affect the Azores while retaining tropical characteristics. The eighth tropical storm, third hurricane, and first major hurricane of the 2006 Atlantic hurricane season, Gordon formed on September 10 in the tropical Atlantic Ocean. It gradually matured into a hurricane as it tracked northward, reaching its peak intensity with winds of 195 km/h (121 mph) early on September 14 while located about 925 km (575 mi) southeast of Bermuda. After becoming nearly stationary, Gordon weakened to minimal hurricane status, although it re-intensified after accelerating to the east. It weakened again after moving over cooler waters, and passed through the Azores on September 20. Shortly thereafter, it became an extratropical cyclone and subsequently affected Spain, Ireland, and the United Kingdom.
Hurricane Michael of the 2000 Atlantic hurricane season caused widespread, but relatively minor damage in Atlantic Canada. The seventeenth tropical cyclone, thirteenth named storm, and eighth hurricane of the season, Michael developed from a non-tropical system to the southwest of Bermuda on October 15. The system was initially subtropical, but rapidly acquired tropical characteristics by October 17. Michael quickly strengthened into a hurricane later that day. By October 20, Michael peaked as a Category 2 hurricane on the Saffir-Simpson hurricane wind scale at a relatively high latitude of 44°N. The storm weakened slightly to a Category 1 hurricane and became extratropical shortly before making landfall in Newfoundland on October 20.
Tropical Storm Laura was a large but short-lived tropical cyclone that developed over the north-central Atlantic Ocean in late September during the 2008 Atlantic hurricane season. Laura's remnants later impacted the Netherlands, Germany, and Norway. The 12th named storm of the season, Laura formed out of a large extratropical area of low pressure located about 1,015 miles (1,633 km) west of the Azores on September 29. Laura slowly developed tropical characteristics throughout the day as it moved over warmer waters. On the afternoon of September 30, Laura had acquired enough tropical characteristics to be designated a tropical storm. Shortly after being declared tropical, Laura began to undergo an extratropical transition, which did not fully take place until the morning of October 1. Laura degenerated into a post-tropical cyclone later that morning, and the final advisory by the National Hurricane Center was issued. The remnants of Laura contributed to heavy rainfall and power outages in the British Isles, the Netherlands, and Norway on October 5 to 8.
The 2011 Atlantic hurricane season was the second in a group of three very active Atlantic hurricane seasons, each with 19 named storms, tied with 1887, 1995, 2010, and 2012. The above-average activity was mostly due to a La Niña that persisted during the previous year. Of the season's 19 tropical storms, only seven strengthened into hurricanes, and four of those became major hurricanes: Irene, Katia, Ophelia, and Rina. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period during each year in which most tropical cyclones develop in the Atlantic Ocean. However, the first tropical storm of the season, Arlene, did not develop until nearly a month later. The final system, Tropical Storm Sean, dissipated over the open Atlantic on November 11.
Tropical Storm Grace holds the record for being the farthest northeast forming tropical cyclone in the Atlantic basin. The seventh named storm of the slightly below average 2009 Atlantic hurricane season, Grace formed from an extratropical cyclone over the Azores on 4 October. It strengthened to attain peak sustained winds of 65 mph (100 km/h) and developed an eye-like feature, although cold sea surface temperatures inhibited the development of thunderstorm activity near the center. The storm lost its tropical characteristics on 6 October, and the storm's remnants merged with a separate system near the British Isles on 7 October.
Hurricane Katia was a strong tropical cyclone that had substantial impact across Europe as a post-tropical cyclone. The eleventh named storm, second hurricane, and second major hurricane of the active 2011 Atlantic hurricane season, Katia originated as a tropical depression from a tropical wave over the eastern Atlantic on August 29. It intensified into a tropical storm the following day and further developed into a hurricane by September 1, although unfavorable atmospheric conditions hindered strengthening thereafter. As the storm began to recurve over the western Atlantic, a more hospitable regime allowed Katia to become a major hurricane by September 5 and peak as a Category 4 hurricane with winds of 140 mph (230 km/h) that afternoon. Internal core processes, increased wind shear, an impinging cold front, and increasingly cool ocean temperatures all prompted the cyclone to weaken almost immediately after peak, and Katia ultimately transitioned into an extratropical cyclone on September 10.
Hurricane Ophelia was the most intense hurricane of the 2011 Atlantic hurricane season. The seventeenth tropical cyclone, sixteenth tropical storm, fifth hurricane, and third major hurricane, Ophelia originated in a tropical wave in the central Atlantic, forming approximately midway between the Cape Verde Islands and the Lesser Antilles on September 17. Tracking generally west-northwestward, Ophelia was upgraded to a tropical storm on September 21, and reached an initial peak of 65 mph (105 km/h) on September 22. As the storm entered a region of higher wind shear it began to weaken, and was subsequently downgraded to a remnant low on September 25. The following day, however, the remnants of the system began to reorganize as wind shear lessened, and on September 27, the National Hurricane Center once again began advisories on the system. Moving northward, Ophelia regained tropical storm status early on September 28, and rapidly deepened to attain its peak intensity with maximum sustained winds of 140 mph (230 km/h) several days later. The system weakened as it entered cooler sea surface temperatures and began a gradual transition to an extratropical cyclone, a process it completed by October 3.
Hurricane Nadine was an erratic Category 1 hurricane that became the fourth-longest-lived Atlantic hurricane on record. As the fourteenth tropical cyclone and named storm of the 2012 Atlantic hurricane season, Nadine developed from a tropical wave traveling west of Cape Verde on September 10. On the following day, it had strengthened into Tropical Storm Nadine. After initially tracking northwestward, Nadine turned northward, well away from any landmass. Early on September 15, Nadine reached hurricane status as it was curving eastward. Soon after, an increase in vertical wind shear weakened Nadine and by September 16 it was back to a tropical storm. On the following day, the storm began moving northeastward and threatened the Azores but late on September 19, Nadine veered east-southeastward before reaching the islands. Nonetheless, the storm produced tropical storm force winds on a few islands. On September 21, the storm curved south-southeastward while south of the Azores. Later that day, Nadine transitioned into a extratropical low pressure area.
The 2017 Atlantic hurricane season was a devastating and extremely active Atlantic hurricane season that became the costliest on record, with a damage total of at least $294.92 billion (USD). The season featured 17 named storms, 10 hurricanes, and 6 major hurricanes. Most of the season's damage was due to hurricanes Harvey, Irma, and Maria. Another notable hurricane, Nate, was the worst natural disaster in Costa Rican history. These four storm names were retired following the season due to the number of deaths and amount of damage they caused. Collectively, the tropical cyclones were responsible for at least 3,364 deaths. The season also had the highest accumulated cyclone energy (ACE) since 2005 with an approximate index of 224 units, with a record three hurricanes each generating an ACE of over 40: Irma, Jose, and Maria. This season featured two Category 5 hurricanes, and the only season other than 2007 with two hurricanes making landfall at that intensity. The season's ten hurricanes occurred one after the other, the greatest number of consecutive hurricanes in the satellite era, and tied for the highest number of consecutive hurricanes ever observed in the Atlantic basin.
The 2018 Atlantic hurricane season was the third in a consecutive series of above-average and damaging Atlantic hurricane seasons, featuring 15 named storms, 8 hurricanes, and 2 major hurricanes, which caused a total of over $50 billion in damages and at least 172 deaths. More than 98% of the total damage was caused by two hurricanes. The season officially began on June 1, 2018, and ended on November 30, 2018. These dates historically describe the period in each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Tropical Storm Alberto on May 25, making this the fourth consecutive year in which a storm developed before the official start of the season. The season concluded with Oscar transitioning into an extratropical cyclone on October 31, almost a month before the official end.
Hurricane Alex was the first Atlantic hurricane to occur in January since Hurricane Alice of 1954–55. Alex originated as a non-tropical low near the Bahamas on January 7, 2016. Initially traveling northeast, the system passed by Bermuda on January 8 before turning southeast and deepening. It briefly acquired hurricane-force winds by January 10, then weakened slightly before curving towards the east and later northeast. Acquiring more tropical weather characteristics over time, the system transitioned into a subtropical cyclone well south of the Azores on January 12, becoming the first North Atlantic tropical or subtropical cyclone in January since Tropical Storm Zeta of 2005–2006. Alex continued to develop tropical features while turning north-northeast, and transitioned into a fully tropical cyclone on January 14. The cyclone peaked in strength as a Category 1 hurricane on the Saffir–Simpson scale (SSHWS), with maximum sustained winds of 85 mph and a central pressure of 981 mbar. Alex weakened to a high-end tropical storm before making landfall on Terceira Island on January 15. By that time, the storm was losing its tropical characteristics; it fully transitioned back into a non-tropical cyclone several hours after moving away from the Azores. Alex ultimately merged with another cyclone over the Labrador Sea on January 17.
Hurricane Gert was a strong tropical cyclone that brought heavy surf and rip currents to the East Coast of the United States in August 2017. Gert originated from a tropical wave that moved off the coast of Africa on August 3 yet failed to organize significantly until August 12, when the system coalesced into a tropical depression east of the Bahamas. A few hours later, the depression became the seventh tropical storm of the annual hurricane season and was named Gert. For the next day, though, further intensification was hindered by the proximity of dry air. Once Gert was able to overcome that on August 14, however, Gert resumed strengthening while moving northwards, paralleling the United States coastline. Gert reached its peak intensity on August 16 at Category 2 status on the Saffir–Simpson scale as it accelerated northeastwards. Thereafter, increasing vertical wind shear and decreasing sea surface temperatures caused Gert to rapidly weaken and transition into an extratropical cyclone on August 17, well east of Atlantic Canada. The remnants of Gert dissipated late on August 18, after they merged with another extratropical cyclone over the open Atlantic.
The 2017–2018 European windstorm season was the third instance of seasonal European windstorm naming. France, Spain and Portugal took part in winter storm naming for the first time this season.
Hurricane Lorenzo, also known as Storm Lorenzo for Ireland and the United Kingdom while extratropical, was the easternmost Category 5 Atlantic hurricane on record. Lorenzo was the twelfth named storm, fifth hurricane, third major hurricane and second Category 5 hurricane of the 2019 Atlantic hurricane season. The storm formed from a tropical wave that moved off the west coast of Africa on 22 September, growing larger in size over the course of its development. It strengthened into a hurricane on 25 September, and rapidly intensified into a Category 4 hurricane the following day before weakening due to an eyewall replacement cycle. After completing the cycle, Lorenzo rapidly restrengthened, peaking at Category 5 intensity on 29 September with 1-minute sustained winds of 160 mph. Steady weakening followed as the storm moved through unfavorable atmospheric conditions. Accelerating northeastward, Lorenzo skirted the western Azores on 2 October, and transitioned into an extratropical cyclone. The extratropical cyclone moved quickly towards Ireland and the United Kingdom and became the first named storm of the 2019–20 European windstorm season, before eventually dissipating on 7 October.
Hurricane Paulette was a strong and long-lived tropical cyclone which became the first to make landfall in Bermuda since Hurricane Gonzalo in 2014, and was the longest-lasting tropical cyclone of 2020 globally. The sixteenth named storm and sixth hurricane of the record-breaking 2020 Atlantic hurricane season, Paulette developed from a tropical wave that left the coast of Africa on September 2. The wave eventually consolidated into a tropical depression on September 7. Paulette fluctuated in intensity over the next few days, due to strong wind shear, initially peaking as a strong tropical storm on September 8. It eventually strengthened into a hurricane early on September 13 as shear decreased. On September 14, Paulette made landfall in northeastern Bermuda as a Category 2 hurricane, while making a gradual turn to the northeast. The cyclone further strengthened as it moved away from the island, reaching its peak intensity with 1-minute sustained winds of 105 mph (169 km/h) and a minimum central atmospheric pressure of 965 mbar (28.5 inHg) on September 14. On the evening of September 15, Paulette began to weaken and undergo extratropical transition, which it completed on September 16. The hurricane's extratropical remnants persisted and moved southward then eastward, and eventually, Paulette regenerated into a tropical storm early on September 20 south of the Azores– which resulted in the U.S National Weather Service coining the phrase "zombie storm" to describe its unusual regeneration. Paulette's second phase proved short-lived, however, as the storm quickly weakened and became post-tropical again two days later. The remnant persisted for several days before dissipating south of the Azores on September 28. In total, Paulette was a tropical cyclone for 11.25 days, and the system had an overall lifespan of 21 days.
Hurricane Epsilon was a strong tropical cyclone that affected Bermuda, and parts of North America and Western Europe. The twenty-seventh tropical or subtropical cyclone, twenty-sixth named storm, eleventh hurricane, and fourth major hurricane of the extremely-active 2020 Atlantic hurricane season, Epsilon had a non-tropical origin, developing from an upper-level low off the East Coast of the United States on October 13. The low gradually organized, becoming Tropical Depression Twenty-Seven on October 19, and six hours later, Tropical Storm Epsilon. The storm executed a counterclockwise loop before turning westward, while strengthening. On October 20, Epsilon began undergoing rapid intensification, becoming a Category 1 hurricane on the next day, before peaking as a Category 3 major hurricane on October 22, with maximum 1-minute sustained winds of 115 mph (185 km/h) and a minimum central pressure of 952 millibars (28.1 inHg). This made Epsilon the easternmost major hurricane this late in the calendar year, as well as the strongest late-season major hurricane in the northeastern Atlantic, and the fastest recorded case of a tropical cyclone undergoing rapid intensification that far northeast that late in the hurricane season. Afterward, Epsilon began to weaken as the system turned northward, with the storm dropping to Category 1 intensity late that day. Epsilon maintained its intensity as it moved northward, passing to the east of Bermuda. On October 24, Epsilon turned northeastward and gradually accelerated, before weakening into a tropical storm on the next day. On October 26, Epsilon transitioned into an extratropical cyclone, before being absorbed by another larger extratropical storm later that same day.
Hurricane Pablo was a late-season tropical cyclone that became the farthest east-forming hurricane in the North Atlantic tropical cyclone basin on record, beating the previous record set by Hurricane Vince in 2005. The seventeenth tropical/subtropical cyclone, sixteenth named storm and sixth hurricane of the 2019 Atlantic hurricane season, Pablo originated from a baroclinic cyclone a few hundred miles west of the Azores Islands. The precursor cyclone formed on October 22, traveling eastward towards the island chain. The system initially had multiple centers of circulation, but they consolidated into one small low-pressure system embedded within the larger extratropical storm. On October 25, the embedded cyclone developed into a subtropical cyclone, receiving the name Pablo. The cyclone continued eastwards, transitioning into a fully tropical storm later that day. Pablo quickly intensified between October 26 and 27, forming an eye and spiral rainbands. At 12:00 Coordinated Universal Time (UTC) on October 27, Pablo intensified into a Category 1 hurricane. The storm continued to strengthen, reaching its peak intensity of 80 mph (130 km/h) and a minimum central pressure of 977 mbar (28.9 inHg) at 18:00 UTC on the same day. The storm quickly weakened the next day, becoming extratropical again, and dissipated on October 29.

(help) Original article's title and date: The future will bring hurricanes to Europe, July 28, 2013The increase in the global-mean values in the period from the 1940s to the present, which is the period when the effect of greenhouse gases due to human activities has been most significant, amounts to about 0.4°C. This is only a tenth of the naturally occurring variation in sea surface temperature seen in the Azores-to-Ireland region in the 3 months prior to Storm Ophelia. This indicates that, insofar as the influence of the sea surface temperature is concerned, the exceptional strength of Storm Ophelia was due to natural variability.
