Another weather warning has been issued for Cornwall - this time for thunderstorms.
Torrential rain has been battering the Duchy on Sunday and Monday morning.
Now the Met Office says we could see thundery downpours and lightning strikes from lunchtime.
There is the risk of travel disruption and a small chance of damage to buildings from floodwater, lightning strikes, hail or strong winds.
The first alert for rain has been extended to last until 10am on Monday 28th June.
The second for thunderstorms will be in force from 12pm until 10pm on Monday 28th June.
What can we expect?
The Met Office says:"Many places missing the worst, but scattered torrential thundery downpours may bring some impacts, such as flooded roads". We can expect:
- Spray and sudden flooding could lead to difficult driving conditions and some road closures.
- There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.
- There is a small chance of fast-flowing or deep floodwater.
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.
- There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.
The Met Office forecast states: "Following clearance of overnight heavy rain, there is the potential for thundery downpours to develop across parts of southern England on Monday afternoon, lasting well into the evening.
"Where these form, they could prove to be slow-moving and produce large amounts of rainfall, with 20 to 30mm falling within an hour and perhaps a few places seeing 50 to 60mm in 2-3 hours.
"Lightning, hail and gusty winds may prove additional hazards in a few locations".
