Residents in the north and north-east are warned of flooding as more rain is forecasted to hit the region.
The Met Office issued a yellow warning for thunderstorms overnight for the area, which could lead to some power cuts and travel delays.
The Scottish Environment Protection Agency (Sepa) has since issued a flood warning for the north and north-east too.
The amber alert reads: “Thunderstorms are expected across Scotland from midnight on Tuesday and through Wednesday morning, which could cause flooding impacts in this Flood Alert Area.
“However, the heaviest showers will be localised, so not all areas will be affected. The greatest risk is if these occur over urban areas and the transport network, which could see flooding from surface water. This could include flooding to low-lying land and roads, difficult driving conditions and flooding of properties.
“There is also a risk of localised flooding from small or fast-responding rivers should the heaviest showers occur over these areas.”
The warning covers Aberdeen and Aberdeenshire, Argyll and Bute, Caithness and Sutherland, Easter Ross and Great Glen, Findhorn, Nairn, Moray and Speyside, Orkney, Skye and Lochaber and Wester Ross.
