In the wettest UK winter in recorded history, roads turned into rivers and an unprecedented number of yellow, amber and red warnings were issued as storm after storm swept through the UK.

Stewart responds when a woman is stranded alone on the M62 in torrential rain. Rob helps a family with a three-year-old child are locked out of their car, 500 metres up in Snowdonia. Malcolm is called to help stranded motorists during a full-scale flood in the village of Whalley.
