Scots have been warned to expect travel delays, flooding and power cuts as the country is hit by thunderstorms from Wednesday.

A yellow weather warning has been issued for most of the country including Glasgow and Edinburgh.

The Met Office say that thunderstorms are likely and could bring flooding in places and travel disruptions.

Homes and businesses are also at risk of damage from flood water and there is a chance that the storms could cause power-cut.

The warning is in place for 24 hours from midnight on Tuesday.

Commuters have been told to expect difficult driving conditions and road closures throughout the day.

The Met Office said: "Where flooding or lightning strikes occur, there is a chance of delays and come cancellations to train and bus services."

STV Weather Presenter Sean Batty said: "A deep low pressure system for the time of year is currently spinning its way up from the south of England, which will bring increasingly unstable air and thunderstorms in the coming days to Scotland. By unstable, I mean air will move quickly and to a great height vertically creating large clouds known as cumulonimbus, which are also known as thunder clouds.

"Thunderstorms are most likely across Wester Ross, Inverness, Moray, Lochaber in the north later on Tuesday. Further south the risk is across south Lanarkshire, Ayrshire and Dumfries and Galloway. These storms could bring some torrential downpours of rain and localised flooding that could develop quickly, especially on roads where drains are blocked. As is always the case during lightning, there's a possibility of power cuts.

"Thunderstorms looks like being an issue for the next wee while, with Wednesday, Thursday and the weekend being the main days of activity. The risk on Wednesday covers a much wider area with the south Highlands, central and southern Scotland at risk. The risk on Thursday is in a similar area and for the weekend the focus remains in the west and central parts, including the south west.

"As is the way with thunderstorms, these will be localised meaning that some areas may manage to escape them, while a few miles down the road there could be a deluge. Watch my Twitter account for updates in the coming days."
