A severe flood warning has been issued for the entire Cornish coastline with fears of significant flooding tonight and tomorrow.
The warnings come as an area of low pressure is set to bring high winds, which, combined with a storm surge and high spring tides, could see coastal defences overtopped.
The severe warning is the highest level of warning issued, and urges residents living in affected areas to take action to ensure they are not in danger.
A statement issued by the Environment Agency this lunchtime reads: "Overtopping of coastal defences is likely with high energy large waves and spray combined with high spring tides and high winds.
"Flooding is expected at exposed coastal locations.
"Gusts of wind of up to 65 miles per hour and large waves of 6-9 metres are forecast.
"Beaches, coastal promenades, roads and footpaths will be extremely dangerous.
"The public are advised to avoid these areas. We will be monitoring the situation and will update as required."
High tide is due at around 6am tomorrow, which will coincide with winds gusting up to 65mph striking the county.
The Met Office has already issued a severe weather warning for the county for the same period.
A further weather warning has also been issued for Sunday with more heavy rain and gales expected.
