Storm Gerrit swept through Yorkshire this week causing new flood warnings as a “supercell storm” battered the region.

Heavy rain caused river levels to rise and roads were subsequently flooded – with several being closed, including the A1 northbound between J52 and J53. Several trains were also cancelled yesterday (Dec 27).

The storm battered the region with reports of a tornado in Greater Manchester and Yorkshire overnight and residents took to social media in shock at the weather.

One said: “The loudest & longest thunderclap that I’ve ever heard at 2.07am in Dent. Must have been this.”

Another added: “Woke me up in Lupton, thought our barn had collapsed.”

The Met Office said: “Last night a supercell thunderstorm crossed Greater Manchester causing damage. 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.”

According to the National Weather Service, Supercells are the least common type of thunderstorm, but they have a high propensity to produce severe weather, including damaging winds, very large hail, and sometimes weak to violent tornadoes.
