Cornwall Council has urged residents affected by the flash flooding in the last 24 hours to clean up safely and keep evidence of flood damage.
The small coastal town of Hayle in West Cornwall has been hit by sever flash floods after torrential rainfall last night and this morning.
Around 30 premises in the town and two in St Erth have been affected by floodwater and part of the A30 was shut after Devon and Cornwall Police declared a major incident.
With more heavy rain forecast tonight from 11pm, residents at risk of flooding are advised to be prepared and to put out sandbags and move valuable possessions from ground level.
The council has advised residents using portable heaters to dry indoors to ensure there is good ventilation and to be careful of carbon monoxide poisoning.
They also warned people not to turn on gas or electrics if they may have been exposed to floodwater, and advised those affected to contact family and friends for support.
