Storm Callum is to batter Scotland, bringing 80mph winds and 100mm of rain to parts of the country.
A weather warning has been put in place for western and northern areas on Friday and Saturday.
Gusts of 80mph are expected as well as a risk of homes flooding and power cuts.
STV weather presenter Sean Batty said: “The worst affected areas will be the north and west of the country with severe gales developing and a risk of storm force winds in some of the more exposed parts of the north west.
“It’s likely gusts of around 80mph will be recorded in the Hebrides and the north-west.
“The track of this storm is a bit further north than Storm Ali, so therefore Callum shouldn’t be as damaging as Ali was in central parts of the country.”
Storm Callum is also predicted to bring major travel disruption to parts of the country.
Sean added: “Being a little more into the autumn now, you would also expect less tree damage as there are now less leaves on the trees.
“Very rough seas can be expected with a risk of waves overtopping sea walls, especially in the north west of the country.
“There will be another spell of heavy rain, with as much as 100mm possible in some parts of the Borders and Dumfries and Galloway.
“This will increase river levels and because drains are now blocked by fallen leaves in some areas, could lead to localised flooding issues again.”
The extreme weather comes just weeks after Storm Ali battered the country, leaving 16,000 homes without electricity.
Buildings were damaged, bridges were closed and trains were cancelled.
School pupils in Dumfries and Galloway were banned from walking home over safety fears due to the storm.
