A Met Office warning of heavy rain has been issued for the next two days in Devon.
At 6.25am the yellow warning, which is the lowest of its kind, was put in place to last between 6pm tonight and 6am on Wednesday morning.
Heavy showers, including thunder and hail, are set to hit the region and will continue to affect the South West through Monday, Tuesday and early Wednesday.
The agency is warning people to be aware of the risk of flooding as the rainfall hits ground which is already saturated from recent storms.
Up to 40mm of rain is expected in some places overall, with up to 25mm likely to fall in just six hours.
A chief forecaster said: “Further bands of showers running into southern counties have the potential to produce intense bursts of rain, these quickly leading to localised impacts given the very saturated ground.
“Hail will be an additional hazard associated with some of the heaviest showers. It won't be raining all the time, with some drier interludes likely but on the other hand, longer spells of rain may occur, more particularly in the southeast overnight into Tuesday and again, perhaps more widely, overnight into Wednesday.”
