Two sections of the M4 in south Wales which were flooded in the wake of Storm Frank have now been 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 but it has now reopened.

The Met Office weather warning for rain was in place until 18:00 GMT.

Strong winds led to the closure of one lane in both directions of the M48 Severn Bridge in Monmouthshire.

Natural Resources Wales said less rain fell overnight than expected but warned some rivers would be very high, fast flowing and dangerous.

Rivers were expected to peak by early afternoon.

Localised flooding has been reported in Pontypool in Torfaen, Cowbridge in the Vale of Glamorgan, Ferryside in Carmarthenshire and Llanishen in Cardiff.

Three flood warnings are in place for the Lower Dee Valley in Wrexham, Abergwili in Carmarthenshire and Pontargothi and Pontynyswen in Carmarthenshire.

Several flood alerts have been issued across Wales.

On Anglesey, ferry services between Holyhead and Dublin have been cancelled while phone lines were brought down in Llansadwrn and Penmynydd.
