A number of flood alerts are in force, with heavy rain and strong winds hitting the county [2 November].
They include the Rivers Exe, Teign and South Devon Rivers. A full updated list can be found here.
The Environment Agency warnings says: "Heavy rain is forecast from the early hours of Saturday 2nd November, which will last throughout the day. This is likely to be widespread and persistent with the potential for surface water and river flooding throughout Saturday.
"Widespread totals of around 20-40mm of rain are expected. There is potential for localised totals of up to 80mm particularly on higher ground. The forecast is unclear on the precise location of these areas in Devon."
Highways England said in a statement: "Road users are advised to take extra care when travelling and consider whether their journey is necessary before setting out, particularly if they are driving a high-sided vehicle or they are travelling via a major bridge."
"If the journey is essential, drivers should allow plenty of extra time and check the latest weather forecast and road conditions before setting out."
A yellow Met Office rain is in force for much of Devon until midnight tonight [2 November], whilst a wind warning for the South West is in place until 6pm.
