Conall, the third named storm of the season, has caused further disruption in the UK. On Wednesday, trains were cancelled in parts of southern England, and the Met Office issued a warning about possible power outages and traffic delays.

In certain areas of south and south-east England, up to 40 mm of rain fell overnight, and another 5 to 8 mm was predicted to fall throughout the day.

A severe weather warning was issued by the Met Office for parts of Essex, Kent, Surrey, and West Sussex in addition to London.

Because Conall was predicted to deliver severe gusts to the Netherlands, the Met Office's partner, the Dutch forecaster KNMI, named the storm.

On Wednesday morning there were no trains between Ascot in Berkshire and Aldershot in Hampshire and part of a line was blocked on the Isle of Wight. There was also train disruption across the Thameslink, Gatwick Express and Southern networks.

Further west the impact of the weekend storm, Bert, meant there was disruption for trains between Hereford and Newport in south Wales and in the south Wales valleys.

Almost 100 flood warnings remained in place for England and Wales and there was one severe flood warning – meaning danger to life – for the River Nene at the Billing Aquadrome in Northamptonshire.

The Environment Agency said the situation on the Nene “remains hazardous”. It added: “There is danger to life. Keep yourself and your family safe. Severe flooding is expected to continue. Please stay evacuated from the area.”

Storm Bert left more than 500 homes and businesses in England and Wales flooded, turned roads into rivers and saw winds of more than 80mph.
