Met Office issues miserable 16-hour rain warning for Devon and Cornwall

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."

What to Expect

• Flooding of a few homes and businesses is possible

• Spray and flooding on roads probably making journey times longer

• Bus and train services probably affected with journey times taking longer

The warm and sunny weather is set to turn from 1pm on Sunday when northern and eastern parts of Devon fall under a thunderstorm warning.
