Aftermath of Storm Desmond; totals, heights and speeds

Mon 8th Dec 2015 Update on rainfall totals 
341.4mm of rain at Honister Pass, new rainfall record for 24 hours. Thirlmere also recorded 322.6mm which also beat the previous record.
In 38 hours Thirlmere recorded 405mm of rain 6pm 5th to 8am 6th Dec, 16 inches of rain! Figures from Environment Agency, confirmed by UK Met. Office

Sunday 7th Dec The news coverage from Saturday showed flooding from Scotland, N.Ireland, Isle of Man, N.Wales and N.England. The trailing fronts from Storm Desmond have brought a weekend of severe weather to many parts of the UK. The gales and damaging gusts began on Friday and returned during Saturday as a secondary low developed. And boy, did it rain. Worst hit were Cumbria and the Scottish Borders, where there were numerous severe flood warnings from the Environment agencies as rivers burst their banks and Met Office Red weather warnings for the sheer amount of rainfall.

Trains were cancelled with landslides on the lines or rails flooded, some services are still suspended. Bridges are closed due to debris or structural damage. Ships were damaged in the high seas and thousands of homes were without power for a time. Roads that were submerged now have reappeared but are damaged and covered in sludge. The Army came to help in the NW as sandbags and flood gates or defences were just not enough. For businesses and properties which flooded on Saturday, now it is the depressing, dirty and saddening clear up time as Keswick and Hawick in particular try to recover, once more. Inspections and recoveries will continue in earnest today.

WIND STRENGTHS

Capel Curig, N.Wales recorded a gust of 90mph at 1am on Sat, NE Scotland and Co.Down G78mph and S.Yorkshire G77mph. These sites all reaching severe gales for their mean speeds and even along the south coast of England, rather exposed, the Needles lighthouse saw Storm Force winds.

Most of the Scottish football matches were postponed due to waterlogged pitches or high winds. Part of a Cineworld cinema roof came loose in Glasgow on Saturday afternoon. In London, a man died when a gust of wind blew him into the side of a moving bus.

WHAT NEXT?

The severe weather has now cleared. Hawick has now cleared it's severe flood warning status. However, Cumbria keeps it's High then Medium risk of flooding as river levels stay high, there are still impacts to communities and roads closed. By Tuesday, the levels over N.England should have fallen to LOW. Environment Agency 3 day flood risk.

There is more rain in the forecast, perhaps another 25mm 1" for flood hit areas, which although in itself is not that much, it is totally unwelcome to the flood hit areas. There is also the possibility of further wet and windy weather Weds/Thurs. Although, not expected to be as severe as the weekend's events this next system will certainly need to be kept an eye on.
