The Met Office reported a “supercell thunderstorm” across Greater Manchester last night (December 27).
In the post on its official X (formerly Twitter) account, it added: “We know from our Dopplar radar that it had a strong rotating updraft. Whilst we don’t yet have surface data to confirm, the presence of these features suggests a tornado at the surface was likely.”
Is Storm Gerrit a tornado?
With Storm Gerrit causing damage, travel disruption and danger to life, you might be wondering if it is a tornado.
It is important to note that there are no tornado warnings currently in place.
If Storm Gerrit doesn’t currently qualify as a tornado – when was the last time the UK experienced one?
When was the last time the UK had a tornado?
Tornados are categorised using the International Tornado Intensity Scale (The T Scale) which ranks the event based on separate wind speed, track length, track width and track area, according to the Tornado and Storm Research Organisation (TORRO).
The last time the UK experienced a T7 tornado (strongly devastating winds) was December 8, 1954 when it hit Gunnersbury in London.
Meanwhile, the most recent T6 tornado (moderately devastating) was on July 28, 2005 (rated T5-6) which hit Birmingham.
TORRO notes that the most intense tornado on record for the UK (and England) went through Welbourn, Wellingore, Navenby and Boothby Graffoe in Lincolnshire on October 23, 1666.
The Welbourn tornado has been rated at T8-9 with a reported maximum track width of 200m and a track length of 5km.
