Huge downpours of rain are set to swamp England as more than 100 flood alerts have been issued.
Heavy rain has been forecast throughout the week by Met Office forecasters following a wet and blustery weekend.
The Environment Agency (EA) has issued 50 flood warnings in response and 131 less severe flood alerts across the country, most of which are for waterways in the south of England.
Pictures and videos show parts of St Ives under water after waves toppled over the seawall causing seafront roads to be closed.
There is particularly high flooding concern for the River Severn near Gloucester, properties along the Somerset coast in and around Portishead, and several warnings for groundwater flooding across the West Wiltshire Downs near Warminster.

Discussing the weather for this week, the Met Office said on its website: ‘Heavy rain will [tonight] move into western areas later in the night with brisk winds. Staying frost free under the blanket of cloud.
‘Outbreaks of rain will spread across the UK tomorrow, turning heavy at times.
‘Local flooding is probable from groundwater during the next five days in parts of the South of England.
‘Local flooding from rivers and surface water is possible across parts of the North of England on Wednesday and Thursday. Lands, roads and some properties could flood and there could be travel disruption.’
It comes after heavy rain lashed down on Sunday, the heaviest of which was more than 21mm of rain in Warwickshire in just a few hours.
In Cornwall, the EA has said a high tide will be joined by strong winds, resulting in big waves hitting coastal areas this morning.
People have been advised to avoid driving through flood water and be mindful of local weather conditions.
