A severe weather warning has been issued for Cornwall with heavy rain due to sweep into the county.
The Met Office issued the warning as the Atlantic weather system moves in.
The Environment Agency also warned of possible floods in the area.
The Met Office weather warnings are in place for all of Cornwall on Friday and for most of the county with exception of the far west on Sunday.
Anthony Astbury, Met Office deputy chief forecaster, said: "Everyone is advised to keep up to date with the latest forecasts and warnings and plan ahead if they are travelling during this change from icy to mild conditions."
Phil Rothwell, Environment Agency Flood Risk Manager, said: "A combination of rain and snowmelt over the weekend will increase the risk of flooding especially in South West England, Wales, the west Midlands and northern England. We are closely monitoring the situation and have teams ready to respond to any potential flooding."
