'Bomb cyclone' Storm Dennis continues to wreak havoc on Sunday with flight cancellations, road closures and severe flooding across the UK.
The Environment Agency has issued 124 flood warnings and 322 more alerts as spells of heavy and prolonged rain are expected to hit northern and parts of southern England.
The agency recorded highest levels on the River Ouse in flood-hit York and expected the river to peak on Monday evening.
The unsettled weather conditions are set to bring up to 80mm of rainfall on Sunday, with hundreds of homes at risk of flooding.
The Met Office has now issued a rare red rain warning for south Wales, with extensive flooding likely and communities facing being cut off.
People residing near the Scottish Borders have been warned to expect 'extensive flooding to properties and businesses, with many roads impassable'.
The Met Office has issued eight weather warnings - three yellow wind warnings and five amber rain warnings - covering most of the UK today.
It comes after Storm Dennis' winds peaked at 87mph on Saturday and six inches of rainfall fell.
British Army troops have been deployed to support flood relief supports in West Yorkshire, as well as Scotland.
Defence Secretary Ben Wallace said: "Our armed forces are always ready to support local authorities and communities whenever they need it. The rapid response of the Army today will help with provision of flood relief to local communities in West Yorkshire."
Storm Dennis claimed two lives yesterday - a 19-year-old teenager was died after entering the water at Herne Bay in Kent, while a man died near Margate - also in Kent - after going overboard from a Maltese-registered tanker that had anchored off the coast.
Met Office Chief Meteorologist, Steve Willington, said: “ Storm Dennis will bring another very unsettled spell of weather this weekend with a risk of flooding, particularly in parts of England and Wales and also southern Scotland, where snowmelt will add to the flood risk.
"With Storm Dennis bringing further heavy and persistent rain over the weekend, there is a risk of significant impacts from flooding, including damage to property and a danger to life from fast flowing floodwater.
"We are advising people to sign up for flood warnings by phone, text or email and to access the latest safety advice on gov.uk by searching ‘sign up for flood warnings’."
Network Rail has advised passengers to expect disruption on many routes due to flooding and to allow more time for their journeys.
Meanwhile, people living near the railway are being urged to secure any loose items in their gardens, after several trampolines were blown on to tracks and overhead electric wires last weekend, blocking lines.
