The Met Office has issued a yellow weather warning for rain this week for parts of the UK, including north of the boarder.
The downpours are due to impact Dumfries and Galloway, Ayrshire and Renfrewshire on Thursday and on Saturday and Sunday, all of Strathyclyde, Central, Tayside and Fife, Highlands and Eilean Siar, South West Scotland and Lothian Borders will also be affected by the bout of extreme weather.
So far, Friday appears to be free from weather warnings in Scotland.
Experts warn the areas most affected by the upcoming spell of bad weather are already saturated which will increase the risk of flooding.
A statement on the Met Office website reads: “There is the potential for some very unsettled weather through the coming weekend, especially across southern, central and western Scotland with periods of heavy rain expected through Saturday and, after a respite overnight, Sunday.
"The rain will fall onto already saturated ground increasing the risk of flooding.”
It goes on to warn there is a small chance that homes and businesses could be flooded, causing damage to some buildings and fast flowing or deep floodwater could cause danger to life.
Travel may be affected due to flooding and wet conditions on roads and power cuts and loss of other services to some homes and businesses is also possible.
Storm Alex recently battered the country earlier this month as it brought heavy rainfall to most parts of the country including the Lothians and the North East.
Pictures of the aftermath showed entire sports pictures under water, burst bridges and flooded railway lines.
