The example below details an event that happened in southern Scotland, Northern Ireland, northern England and north Wales. It would have generated an amber warning of wind with the new warning service.
Weather situation on 11 November 2010
A very deep area of low pressure brought severe gale force winds and heavy rain to much of the UK overnight from 11 to 12 November. The highest winds were across north Wales, Northern Ireland, northern England and southern Scotland, and resulted in damage and disruption.
The highest gusts recorded on 11 November 2010 included:
|Aberdaron, Gwynedd||81mph (70kn)|
|Needles Old Battery, Isle of Wight||79mph (69kn)|
|High Bradfield, South Yorkshire||78mph (68kn)|
|Lake Vyrnwy, Powys||78mph (68kn)|
|Winter Hill, Lancashire||77mph (67kn)|
|St Bees Head, Cumbria||75mph (65kn)|
|Blackpool Squires Gate, Lancashire||74mph (64kn)|
|Ronaldsway, Isle of Man||73mph (63kn)|
|Mumbles Head, West Glamorgan||73mph (63kn)|
|Walney Island, Cumbria||70mph (61kn)|
|St Angelo, County Fermanagh||70mph (61kn)|
A key difference between this and the strong winds that affected England and Wales on 18 January 2007 (LINK TO RED EVENT) was the timing. The strongest gusts during this event occurred during the evening and overnight. This would be one of the factors taken into consideration when assessing the impact. As such, on this occasion amber impacts would be more appropriate than red.
