What Katie did – a review of Easter Monday’s storm Katie

Storm Katie may never have been destined to be a record-breaker, but nonetheless she certainly swept dramatically over southern Britain during the night of Easter Sunday and into the morning on Easter Monday.

With her track across southern Britain, storm Katie – the 11th named storm since last autumn – first made landfall in Cornwall and then exited into the North Sea from the Lincolnshire coast during the latter part of the morning.

Mark Wilson is a Met Office forecaster. Reviewing the progress of storm Katie, he said: “The maximum gust speed recorded was 106 miles per hour at 5am on the Needles on the Isle of Wight. The Needles is a very exposed site and regularly records the strongest UK gust speeds. The speed of 74 miles per hour recorded at 7am at St Catherine’s Point on the island is more typical of values recorded elsewhere across southern England.

This map shows the maximum gust speeds recorded in Knots (Kt) across the UK during storm Katie. The maximum gust was 92 Ks, which equals 106 miles per hour.

“Given the southerly wind direction, it’s no surprise that most of the highest wind gust speeds were recorded in southern England. In fact most of the 30 UK stations recording the highest wind gust speeds are south of the M4 corridor.”

Along with the wind, the weather system associated with storm Katie also brought heavy rain. Up until 9am, Leek in Staffordshire had recorded 33mm of rain, while Exeter had recorded 26mm. Some places in the North Midlands and Wales also recorded snowfall overnight.

The progress of storm Katie on Easter Monday was covered by three National Severe Weather Warnings: including an Amber warning for wind in south-east England; and two seperate Yellow warnings covering swathes of southern Britain for both wind and rain.

  1. William Read says:

    Leek is in Staffordshire, not Derbyshire. My back garden rain gauge recorded over an inch of rain overnight, and there was snow lying in Stafford at 0700hrs Monday.

  2. When does the 2015-16 wind season officially end? 31 August perhaps?

  3. It was the storm’s track rather than the wind direction that explained the highest gusts being in the south of England. The southerly wind would only be relevant for the strength close to the south coast.
