Storm Dennis is unlikely to be as serious and disruptive as last weekend's Storm Ciara.
"Storm Dennis has the potential to bring very strong winds and transport disruption during Sunday and Monday morning", said a Met Office spokesman.
Keith Ashcroft, the EA's area director for Cumbria and Lancashire, said: "We knew there was a storm, which we were expecting to be incredibly windy, but not that wet".
"Because the rain came though so strongly and the river rose so quickly, we physically wouldn't have had time to put the barriers up".
"Around 20-40 mm of rain will fall widely with 50-80 mm likely across parts of northern and southern England".
The Met Office issued the amber warning this morning, with heavy and prolonged rain expected from just after midnight on Sunday right through until 6pm.
"There is a possibility that there will be wind warnings and rainfall warnings for periods over the weekend", she said.

There are also several amber warnings in place for torrential rain in parts of Wales and England.
