Storm Desmond set to unleash 75mph winds and up to 200mm rainfall in 30 hours

The Met Office and Met Eirann have named the fourth storm of the autumn/winter season so far.

Storm Desmond - a deep area of low pressure is currently tracking north of the UK, however it's producing it's strongest winds further south, which lies across northwestern parts of Britain where there's a tight squeeze in the isobars.

During tonight and Saturday gusts of wind are likely to hit 60 - 75mph on exposed northwestern coastal areas of Scotland in particular.

The wind will also be accompanied by heavy and persistent periods of rain.

An Amber Warning is also in force because of an escalated flooding risk as a staggering 150 - 200mm rainfall is forecast in the next 30 hours over the most prone mountainous regions of Southwest Scotland and Northwest England.

A Yellow Warning has also been issued by the Met Office across a much wider area of Scotland, N. Ireland, N. England and N. Wales. As all this water runs off the high ground in the next two days river levels will rise and the ground will remain very saturated.

The wet and windy weather will travel southeastwards across Britain during the course of the weekend fairly slowly. It does mean that whilst it'll be stormy in the north overnight and during Saturday, southern parts of Britain will be a lot drier, although it will be windy.

By Sunday the wind and rain will be across the south, but by this time it would have run out of steam. Although it'll still be windy, northern areas will be a lot drier and brighter.
