It was in 1987 that weatherman Michael Fish infamously took to the airwaves to reassure viewers that the country was not about to be battered into submission by a huge storm. ‘Earlier on today, apparently, a woman rang the BBC and said she heard there was a hurricane on the way,’ he said. ‘Well, if you’re watching, don’t worry, there isn’t.’ A few short hours later, the Southeast was hit by the worst storm since 1703, leaving 18 dead and Fish’s reputation in tatters.
Nearly 900 years earlier contemporary meteorologists fared no better with their predictions when London was devastated by a tornado. In fairness, we can’t blame Fish for that one, but it does go to prove it’s dangerous to put too much trust in weathermen.
The tornado hit on the morning of 17 October 1091. Modern experts have estimated the winds could have reached speeds in excess of 230mph (370kmph) and the capital’s many flimsy wooden structures offered little resistance to the onslaught.
‘At the hour of six a dreadful whirlwind from the south east coming from Africa blew upon the City and overthrew upwards of six hundred houses,’ recounts The Chronicles of London Bridge, published in 1825. ‘Several Churches greatly damaged the Tower and tore away the roof and part of the wall of the Church of St Mary-le-Bow in Cheapside. The roof was carried to a considerable distance and fell with such force that several of the rafters being about twenty eight feet [8.5m] in length pierced upwards of twenty feet [6m] into the ground and remained in the same position as when they stood in the Chapel.’
The tornado also had quite a destructive effect on the Thames. ‘During the same storm too the water in the Thames rushed along with such rapidity and increased so violently that London Bridge was entirely swept away,’ reports the Chronicles, ‘whilst the lands on each side were overflowed for a considerable distance.’
The sight of the bridge being washed away by the river must have been as spectacular as it was terrifying for Londoners and a poor reflection of the craftsmen who had erected it just 25 years earlier on the orders of William the Conqueror. King William II had it rebuilt but the latest incarnation of London Bridge lasted little longer than its predecessor, burning down in 1136.
It would be another 600 years before the traditional nursery rhyme ‘London Bridge Is Falling Down’ was first recorded in England but it’s not hard to guess where its anonymous creator drew inspiration from.
