British Isles weather, December 2015

Fronts associated with storm Frank crossed the British Isles on the 30th. A mild night was followed by a mild day with heavy falls of rain in parts of Scotland, NW England and N Wales that led to serious flooding in parts of Scotland. It was a dull day, and windy in the N and W due to the storm system, while the temperature finally dropped later in the day as a cold front passed through from the W. Two sections of the M4 in south Wales which were flooded in the wake of Storm Frank have were later cleared. Police dealt with three separate crashes where there was standing water on both sides of the carriageway between junctions 35 (Pencoed) and 36 (Sarn). Flooding also blocked one lane on the eastbound stretch at junction 26 for Malpas. Natural Resources Wales said less rain fell overnight than expected but warned some rivers would be very high, fast flowing and dangerous. Localised flooding was reported in Pontypool in Torfaen, Cowbridge in the Vale of Glamorgan, Ferryside in Carmarthenshire and Llanishen in Cardiff. The storm led to more than 1,400 properties losing power in Carmarthenshire, Pembrokeshire, Rhondda Cynon Taff, Swansea and Newport on Wednesday morning; on Anglesey, ferry services between Holyhead and Dublin have been cancelled while phone lines were brought down in Llansadwrn and Penmynydd. Power cuts, widespread flooding and landslips have been reported as Storm Frank continued to batter Scotland. Thousands of homes are without power in the north east, Argyll, the Borders, Highlands, Hebrides and Northern Isles. Ten adults and two children were winched to safety by a rescue helicopter after a Stagecoach bus became trapped near Dailly, Ayrshire. In Aberdeenshire the A93 was closed for 70 miles while a landslip closed the A83 at the Rest and Be Thankful in Argyll, leading to a 50-mile diversion - about 300 tonnes of material washed down hillside, trapping two cars. The Highland main line was closed all day due to flooding. (Rhyl 15.2C, Inverbervie 9.9C maximum, Tulloch Bridge -0.7C minimum, Tyndrum 82.0 mm, Shoeburyness and Dublin Airport 1.6 h. )

There was a widespread ground frost over much of Ireland and Scotland, with an air frost in N and Cent Scotland, on the 31st. Milder conditions elsewhere gave way to colder air following the clearance of rain - as the skies tended to clear from the W. (Isle of Portland and St Helier 11.9C, Lentran 2.8C maximum, Loch Glascarnoch -4.4C minimum, Shap 29.0 mm, Wattisham 6.3 h.)
