Fourteen flood warnings are in place across England as a powerful storm moves across the UK, causing widespread travel disruption and power cuts.
On Monday, gale force winds and rain affected roads, rail and air travel and almost 12,000 homes were without power.
The weather is now easing but fears of flooding are expected to increase in the early hours of Tuesday.
The Environment Agency says the Bristol Channel, Severn Estuary and the Somerset coast are most at risk.
High tides along the south west, southern and west coasts will peak by midnight GMT.
A spokeswoman for the Environment Agency said: "The situation has now improved along parts of the south west and southern coasts."
It is urging people in those areas to stay vigilant, as high spring tides combining with strong winds could cause more localised flooding.
