The Met Office has issued a 16-hour rain warning for Devon and Cornwall. This weekend's stunning weather will come to a crashing halt on Monday when a wall of rain arrives.

The yellow warning is in place from 8am until 11.59pm on Monday and covers most of Devon and Cornwall. The Exeter-based Met Office said heavy rain is likely to bring some transport disruption and possible flooding in a few places.

Up to 50mm of rain could fall in some parts of the region on Monday. The Met Office said: "A band of rain will move east across the area through Monday to bring a spell of heavy and persistent rain.

"Rain will reach Cornwall during Monday morning but won't reach eastern parts of the warning area until Monday afternoon. 20-30 mm of rain is expected to fall widely with as much as 40-50 mm over some hills. Conditions will likely improve across Cornwall through the afternoon, but will persist across the east of the area until the end of the day."
