Met Office Issues Yellow Weather Warning – Wind

Issued at: 11:53 on Thursday 19 November 2015

Valid from: 21:00 on Friday 20 November 2015

Valid to: 15:00 on Saturday 21 November 2015

A swathe of gale force north to northwesterly winds, accompanied by a band of rain and snow, will move south across much of central and southern Britain on Friday night and Saturday. Wind gusts of 50-60 mph are likely, with a lower likelihood of 60-70 mph gusts, perhaps most likely in exposed parts of east coastal England. In any one area, the strongest winds will last for only a few hours, clearing last from southeastern areas of England.

Additionally, some of the snow may settle, this more likely over some of the high ground, for example in north Wales, but there is a possibility of temporary settling snow even at low levels. The worst affected areas may see a few cm but on current evidence, most places will see little if any lying snow. On Saturday morning, ice will be an additional hazard, particularly for higher level routes.

Please be aware of the likelihood of some difficult driving conditions and possible travel disruption.

Chief Forecaster’s Assessment

A major (but temporary) change of weather type will see the winds swing into a more northerly direction, pulling down much colder air across the whole of Britain and western Europe, after what has been an exceptionally mild first half of November. Wintry showers will spread to many northern areas in particular and night frosts will become much more widespread.

Within this northerly flow, a small but quite active low pressure system is expected to develop and transfer south bringing more widespread wintry conditions and gale force winds. In the area covered by this warning, it is the winds that are currently judged to be more likely to produce some impacts, particularly given the northerly direction.

At present details of both wind strengths and snow amounts are uncertain, and so look out for updates to this warning.
