Beginning on 24 February 2018, Great Britain and Ireland were affected by a cold wave, dubbed the Beast from the East by the media, which brought widespread unusually low temperatures and heavy snowfall to large areas. The cold wave combined with Storm Emma, part of the 2017–18 UK and Ireland windstorm season, which made landfall in southwest England and southern Ireland on 2 March.

In contrast to usual winter storms, Emma was not formed as a normal low pressure area along with the jetstream; the initial event was an arctic outbreak due to a disordered polar vortex into Central Europe, transporting not only cold air from Siberia to Europe, but on the way to the British Islands according to the lake effect sent a lot of snow into areas of Great Britain and Ireland.

This weather situation repeated itself on the weekend of 17 and 18 March, but was less severe than on the previous occasion due to the onset of spring. This briefer cold snap was given the name "Mini Beast from the East".

Beast from the East[edit]

The cold spell nicknamed the Beast from the East was caused by a large arctic airmass with anticyclonic structure, stretching from the Russian Far East to the British Isles covering large parts of Asia and almost all of Europe. The anticyclone, centered over Scandinavia,[2] is the dominant high pressure area in the weather system and represents its European part. North Asia was covered by other anticyclones that belong to that giant arctic airmass. The anticyclone brought cold easterly winds into Europe and the British Isles leading to snowfall and sub-zero temperatures as result of freezing air from Siberia.[3][4] Ireland was predicted to experience its worst winter for at least 30 years.[5][6] In the United Kingdom the Met Office issued a red snow warning, meaning a potential risk to life.[7]

The anticyclone, nicknamed 'Hartmut' was such an intense high pressure system that it evolved into an anticyclonic storm. A gust of 187 km/h was registered in the Øvre Dividal National Park in Norway, relatively near to the anticyclonic centre.[8] Other hurricane-force gusts delivered by Hartmut were registered across Europe, particularly over Scandinavia and the British Isles. Such hurricane-force anticyclonic storms are not extremely rare, but occur less often than cyclonic storms of similar intensity.

16 weather-related deaths include that of a seven-year-old girl in Looe, Cornwall Thursday 1 March, when she was hit by a car that slid on ice into a bungalow. On Wednesday 28 February, Stephen Cavanagh, 60, died after trying to save his dog from a lake in Welling, South East London. Also on Wednesday, a 46-year-old man died in a crash and a 75-year-old woman was found dead underneath her car in Farsley. A carer from Glasgow died on her way to work and a 52-year-old homeless man was found dead freezing inside his tent. On Tuesday, 27 February, four people died in two separate weather related crashes. A 20-year-old also died after slipping and falling whilst crossing a bridge in Haddington, East Lothian. This followed the death of a man trying to help another driver in the snowy conditions in Bergh Apton, Norfolk who suffered a heart attack. A 70-year-old also died after being rescued from icy cliffs in Torquay.

Storm Emma[edit]

Storm Emma brought chaos with heavy snow and strong winds to Southern Ireland, South West England and Southern Wales on the 2–3 March 2018 with up to 50 cm of snow in some elevated areas.[26] High winds brought disruption to other parts of Great Britain and Ireland. It also brought rail disruption as several trains became stranded, full of passengers, for up to 14 hours.[27]

Mini Beast from the East[edit]

Following a brief spell of warmer weather, a fresh cold snap nicknamed the "Mini Beast from the East" was forecast to bring another covering of snow on the weekend of 17 and 18 March. However, due to the onset of spring, and a higher sun position, it was forecast that the effect would be less severe than on the previous occasion, as the ground was warmer than before so the snow would melt more quickly.[28][29]

Snow showers began to affect parts of Britain and Ireland on 17 March, with north-east England, the North Midlands, and parts of southern England experiencing the heaviest snowfall. The snow was accompanied by strong winds, forecast to be as high as 70mph, and the Met Office issued an amber weather warning effective from the afternoon of 17 March.[30] Snow showers continued to affect parts of the UK and Ireland on 18 March, with South West England the most severely affected. The adverse weather conditions forced the cancellation of some sporting events, including the Reading Half Marathon, while Ireland's rugby union team, who had won the 2018 Six Nations Championship, cancelled their homecoming "due to heavy snowfall" with no new date confirmed.[31]
