Thunderstorms are forecast to move into the south western Borders from around 8am, bringing with them extremely heavy, isolated downpours of rain, with the potential for hail, significant lightning and strong gusts of wind.
These will move across the region to the north east, clearing the Scottish Borders by late afternoon. It is expected that the worst periods will be between 9am and 11am and 2pm and 3pm.
In some areas up to 50mm of rain could fall over the course of just a few hours, with between 20-30mm of rain falling per hour in the heaviest downpours.
There remains the potential for significant disruption due to the sudden downpours, and the Met Office has indicated that it may escalate the warning to Amber (Be Prepared) if required, and potentially at short notice.
