2016–17 UK and Ireland windstorm season

The 2016–17 UK and Ireland windstorm season was the second instance of the United Kingdom's Met Office and Ireland's Met Éireann naming extratropical cyclones. Substantially less active than the previous season, the season succeeded the 2015–16 UK and Ireland windstorm season and preceded the 2017–18 European windstorm season.

Background
Main article: Winter storm naming in the United Kingdom and Ireland

In 2015, the Met Office and Met Éireann announced a pilot project to name storm warnings as part of the Name our Storms project for wind storms and asked the public for suggestions.[2] The meteorological offices produced a full list of names for 2015–16, common to both the UK and Ireland.[3] A new list of names was released on 19 September for the 2016–17 season.[4] Names in the UK will be based on the National Severe Weather Warning Service, when a storm is assessed to have the potential for an amber 'be prepared' or red 'take action' warning.[4]

Damage≥ £80 million (≥ €90 million)[12]

Storm Angus was named on 19 November, with southern and southeast England, especially along the Channel coast expected to be the greatest affected areas as the storm moves northeast on 20 November.[13][4] The storm was known as "Nannette" in France, Germany, Belgium and the Netherlands.[14] Guernsey, in the Channel Islands, were hit with hurricane-force winds with the highest wind gusts since its 1990 record.[15]

The south-west of England was affected with over 1,000 power outages, mostly in Devon. Residents were evacuated due to flooding near South Molton, Devon. Further flooding was reported in Braunton, Bradiford, Devon, and East Bar, Swanage, Dorset. The high winds affected train service in the south-east, ferry crossing at the Port of Dover and the Brighton 10k run.[10]

The National Grid launched an investigation whether a ship's anchor damaged four of the eight cables of the Cross Channel high voltage interconnector during storm Angus, which would leave it only able to operate at half of its capacity until February 2017.[16]

A 39-year-old woman was found in the sea near Folkestone and was airlifted to hospital; she later died.[17] Russell Sherwood, aged 69, had been reported as missing on the day of the storm: a car was found upside-down in the River Ogmore with his body inside on 23 November.[18]

Damage from Storm Doris in New Barnet, London.

Storm Doris was named on 21 February and impacted Ireland, the UK and the Netherlands on 23 February 2017.[27][28][29] A gust of 94 mph (151 km/h) was recorded at Capel Curig, Wales.[30] On its approach the storm strengthened considerably going through a process called bombogenesis,[31] wherein the central pressure of the system fell at a very fast pace; 24 hPa (0.71 inHg) of pressure in 24 hours to 974 hPa (28.8 inHg).[32][33]

A 32-year-old woman was killed in Swindon when blown with an empty pram into the road.[34] Another woman, a 29-year-old, died in Wolverhampton when debris fell on her in the street.[35][36] A man in his 80s died in hospital on 26 February after the car he was travelling in was crushed by a falling tree.[37] The Shropshire and Wolverhampton incidents were chronicled in the final episode of the second series of Ambulance, a BBC One documentary programme, the following October.[38][39]

A girl was seriously injured when a ceiling collapsed on her at the Southwood School in Milton Keynes.[40] On 23 February 2017, during high winds caused by Storm Doris, a Flybe plane (Flight 1284) from Edinburgh to Amsterdam crash landed on the runway at Amsterdam Airport Schiphol: the rear right landing gear collapsed but there were no injuries.[41]

There was also snow and rain. Road, rail and air travel was disrupted and there were failures in power supply. The storm was described as a weather bomb.[42][43]

Storm Ewan

Storm Ewan was named by Met Éireann four days after Doris on 25 February and impacted Ireland on 26 February 2017.[44] Ewan failed to form a low pressure system and damage was limited in Ireland to strong winds on the south coast.[45]

Season effects

This table lists all known windstorms that affected the UK and Ireland during 2016–2017. It includes their name, duration, peak recorded gust (excluding mountain stations), lowest pressure, areas affected, deaths and damage totals from the two nations. All damage figures are in 2016 pounds sterling and euros. The 2016/17 storm season was described as relatively quiet by the reinsurance broker Aon Benfield's Impact Forecasting division in late February.[46]

IR satellite image of storm Egon 13 January 2017

During the 2016/17 winter 3 storms exceeded the Perils.org insured loss reporting threshold of €200 million, Egon, Thomas/Doris,[47] and Zeus.

(† Zeus was not named by a national meteorological agency but was widely used in French media, believed to be a misappellation of another low named by the Free University of Berlin charts.)

gollark: I don't think objective horror particularly exists.
gollark: There are nonmilitary schools with that, I'm sure.
gollark: You should have tried not going there, retroactively.
gollark: So basically, I would not take that figure very seriously.
gollark: The only source I can find is here (https://alfin2100.blogspot.com/2013/01/the-life-span-of-empires-250-years.html) and this has a dead link to an essay of some kind, and is apparently only aware of about 10 empires.
