A suspected tornado linked to a “supercell thunderstorm” caused damage to about 100 properties in Greater Manchester this week, and a second of these rare storms was confirmed to have hit Morecambe Bay in Lancashire just hours later.
Supercells are rare storms that cause some of the most extreme weather phenomena on the planet. Every thunderstorm has an updraft – a current of air that pulls in moisture from the surrounding area – and a downdraft, which sends rain and hail back to the surface.
