Post-tropical storm Katia - September 2011
In early September Hurricane Katia was forecast to cross the Atlantic and reach the UK as a post-tropical storm, causing widespread strong to severe gale force winds and heavy rain in parts. Accurate forecasts from the Met Office and frequent updates on the progress of the storm helped people in affected areas to prepare and stay safe.
As forecast, a deep area of low pressure which contained post-tropical storm Katia reached the UK on Monday 12 September, bringing severe gales and heavy rain to Scotland, Northern England and Northern Ireland.
In line with our forecast, Scotland and Northern Ireland bore the brunt of the storm, with widespread wind speeds of 60 - 70 mph and gusts of up to 98 mph in the most exposed mountainous areas. There was also heavy rain in parts of Scotland, which resulted in localised flooding in some areas of Central Scotland.
