Motorists and residents can expect a further 24 hours of floods after experts have predicted another night of heavy rainfall.
Two inches of rain fell during 12 hours in the south west last night, and the Environment Agency has told communities in the West Country to expect more disruption.
Up to five inches of rain may fall on already soaked ground tonight, leading to river flooding during the next day.
ITV News' Neil Connery reports:
Strong winds may also come into play, worsening conditions like surface water flooding.
Pete Fox, the Environment Agency's head of flood risk strategy, said: "There is already significant travel disruption due to the wet weather and we would urge people to remain vigilant as further flooding is possible across the South West tomorrow.
"People at flood risk should move their valuable possessions to a safe place before the heavy rain falls later tomorrow.
"We also ask that people stay safe, by staying away from swollen rivers and not attempting to drive through floodwater."
The Environment Agency today put more than 200 flood warnings and alerts in place, mostly in the south west of England and the Midlands.
Emergency services issued warnings to motorists to take extra care on the roads, and Devon and Cornwall Police said there was a risk of drivers losing control of their vehicles.
.A spokesman said: "There are significant incidents of standing water being reported on the roads, and so we need drivers to take extra care and adjust their braking times accordingly."Drivers need to match their speed with the conditions."
