This is that infamous 80s weather blooper (in 1987) when Michael Fish forecast that there wouldn't be a hurricane. Unfortunately, on the evening of October 15th/16th the great storm of 1987 decended upon the southern half of the UK.
Of course, technically, it wasn't a hurricane, but there were hurricane force gusts, so stating that the weather would be "very windy" was a bit of any understatement to say the least!
In his defence, he had actually predicted a storm but just not in the right place. He forecast that the storm would move further south along the English Channel and the British mainland would escape the worst effects. This remainder of his warning is frequently left out of re-runs, and was left out of the video clip above.
