People in Cornwall are being warned of further flooding as heavy rainfall is expected overnight.
Forecasters are predicting more showers into Thursday, with the possibility of heavy localised rain.
The Environment Agency said: “This rain will fall on already saturated ground resulting in a risk of further flooding in Cornwall.”
Heavy rain into Wednesday left villagers stranded, with some needing to be rescued as homes and cars were swamped.
The agency added: “We are monitoring the situation closely. Our teams are on the ground clearing debris from rivers and grates, checking flood defences and assisting emergency services.
“Elsewhere, river levels are now falling and the risk of flooding outside of Cornwall is low. The Met Office predicts a mix of sunshine and showers throughout Thursday and Friday, leading to a low risk of flooding.”
