Flood warnings are in place for almost the whole of the south Cornish coast this afternoon as 24 hours of heavy rain hits the region, as the Environment Agency warns of a risk to properties.

Porthleven, Praa Sands and Mousehole are described as being particularly at risk by the EA, which has issued the second highest level of alert: “Flooding is expected - immediate action required.”

The warning covers the south Cornish coast from Land’s End to Lizard Point, excluding Mounts Bay.

The EA said: “Flooding is expected over the high tides on Saturday evening, Sunday morning, and Sunday evening.

“High water times at Newlyn are Saturday evening at 5:17pm, Sunday morning at 5:41am, and Sunday evening at 6:01pm. Times of high water will vary along the coast.

“High astronomical tides and Force 6 South Westerly winds, combined with offshore wave heights of up to 4m are forecast to cause flooding to properties.

“Expect tides to be around 300mm higher than predicted due to weather conditions. Large waves and spray are likely, so take care near coastal paths and promenades.

“This may cause localised standing water on roads. Do not drive through flood water or waves.

“Locations particularly at risk include Mousehole, Praa Sands, and Porthleven.”

Rain is expected to last until around 3pm tomorrow afternoon, when a break is forecast. However, rain is expected to make an appearance again on Monday morning and continue for most of the day.

Cornwall has escaped the yellow weather warning for rain that covers much of the west of the UK for the next four days.
