The Environment Agency is urging communities to remain vigilant during this weekend’s stormy weather and high tides.
Significant disruption could occur in vulnerable areas throughout the South West.
The Environment Agency has been liaising with the Met Office to understand the impact these might have in the region.
Catchments are already saturated and likely to respond quickly to further rainfall on Friday. Strong winds (Force 5-6) and spring tides will increase the risk of coastal flooding in parts of Dorset, North Somerset, Bristol and the north coast of Devon and Cornwall.
High tides and possible storm surges could cause wave overtopping and localised flooding of roads and properties in exposed coastal locations. The stormy weather is expected to continue into Sunday.
High winds combined with spring tides will result in dramatic waves.
People can stay safe by:
Keeping away from seafronts and promenades when waves and winds are high – respect the sea and resist the temptation to ‘wave watch’ -
Staying informed – check flood warnings and alerts
A spokesman said: "Strong winds and large waves are forecast along the south and west coast of England between Friday and Sunday, coinciding with high tides,’ said Nick Lyness for the Environment Agency.
"Impacts could include flooding affecting some coastal properties and communities. Coastal paths and promenades could be highly dangerous as there is an increased risk of being swept out to sea. People are warned to stay away from the shoreline.
"The Environment Agency is monitoring the situation closely, working alongside partners including the Met Office and local authorities. Environment Agency teams are out on the ground making sure that flood defences are in good working order, monitoring sea levels and preparing to issue flood alerts and warnings."
