The monster storm is verging on being the most powerful North Atlantic storm since records began 196 years ago. The Met Office has warned of flooding in homes and businesses due to five inches of rain set to being lashed. The Met Office has issued both amber and yellow warnings for wind and rain on Saturday and Sunday across the whole of Britain.

The amber warnings for rain will last until 6pm on Sunday.

They are spread across south west England, southern Wales, north west England and south east England. 

The yellow warnings for rain are in place across the whole of Scotland, England, Wales and Northern Ireland during the same time.

People re being urged to be careful while they are out, particularly on the roads.

This comes just a week after Storm Ciara caused travel chaos last weekend.

Paul Gundersen, Chief Meteorologist at the Met Office said: “Another spell of very wet and windy weather is expected for Saturday.

“Although Storm Dennis is currently not expected to be as severe as Ciara, disruption is still likely.”

Saturday is predicted to be the most dangerous day.
