An update of the severe weather warning in place for Saturday shows that Cornwall is set to miss the worst of forecast torrential downpours.
Forecasters warned earlier this week that the public should be aware of the "potential for localised flooding due to the intensity of these storms", however adding that the location of the heaviest rainfall is "uncertain".
The area covered by the warning has now moved north, and while the forecast for Cornwall is now for showers, it is likley to avoid the heavier downpours.
The wet weather is due to warm, humid air likely to be pulled northwards from France late on Friday and during Saturday.
The chief forecaster at the Met Office said: "Within this airmass, there is an increasing likelihood that heavy, thundery showers will break out. It is likely that many places within the current broad warning area will miss the worst of the storms."
