The warning from Owen Paterson came after a meeting of the Government's emergency committee Cobra, where ministers heard that the Environment Agency will issue "severe" flood warnings - the highest category available.
In London the Thames Barrier has been closed to protect those living along the river, and power companies and councils are being told to brace for the impact of the storms.
Mr Paterson told Sky News: "I have just chaired a further Cobra meeting as we have further bad weather coming in. We are looking to have a combination of exceptional rain, wind and a surge in sea and high tides and so there are nearly 50 warnings put out around the whole of the west coast and south coast.
"We had a range of ministers from right across Government attending the meeting, who will be working very closely with local councils, power companies, utility and transport companies, making sure that all of those organisations are absolutely prepared for the bad weather that is coming."
