More than 120,000 lightning strikes were recorded in 12 hours over southeast England and northern France on May 28, 2017, as a superstorm “the size of Wales” swept across the Channel.
Between 6pm on Sunday and 6am on Monday morning there were up to 500 flashes a minute.
Experts described the conditions as an “intense, dangerous supercellular storm”. A supercell storm is the least common — and most perilous — of the four classifications of thunderstorms.
