The Great Storm of 1987: How weather forecasting has changed
The night of Monday 15 October marks 25 years since the UK's Great Storm of 1987, in which 18 people died as winds reached speeds of 115mph.
The Met Office famously failed to predict the intensity and location of the storm, which took residents in the south of England by surprise.
It did, however, kick-start a revolution in weather forecasting. New technology and research means forecasts are now more accurate than ever.
Forecaster and BBC Weather Presenter Peter Gibbs visited the Met Office headquarters in Exeter to see what has changed over the past 25 years.
Peter Gibbs reports on the Great Storm for PM on BBC Radio 4, on Monday 15 and Tuesday 16 October at 1700BST.
