Storm Corrie is set to thrash Scotland with gusts of up to 90mph, with Nicola Sturgeon issuing an urgent warning.
The country is still recovering from the chaos wreaked by Storm Malik on Saturday.
The storm triggered the cancellation of nearly 200 trains and busy routes were blocked by fallen trees.
One woman, 60, was also tragically killed when she was crushed by a fallen tree in Aberdeen.
Storm Corrie is set to bring further devastation on Sunday, with The Met Office issuing further weather warnings.
A yellow weather warning is affecting the country from 3pm on Sunday, January 30, until 12pm on Monday, January 31.
But a more severe amber weather warning has been issued for a large swathe of Scotland from 5pm on Sunday until 6am on Monday- which stretches from Dundee to Thurso.
First Minister Nicola Sturgeon has warned that some Scots could be without power for the rest of the weekend as Storm Corrie rolls in.
Ms Sturgeon chaired a Scottish Government resilience meeting on Saturday as winds of more than 100mph were recorded.
She issued a grave warning on Twitter, saying the impact of Storm Malik had been "severe", but that Storm Corrie "may be more severe for parts of Scotland".
"Unfortunately as Malik subsides, Storm Corrie is about to hit from late tomorrow afternoon & may be more severe for parts of Scotland - eg Highlands, Grampian, Tayside than anticipated," she said.
"Please follow @metoffice for any updates to the weather warnings in place."
There are currently 209 power outages across Scotland, most of which are in the north-east or north of the country, according to the Scottish and Southern Electricity Networks.
"Impact of Storm Malik is severe," the First Minister said.
"Power companies working hard to restore supply ASAP but many SSEN customers, esp in (north east) may be without power over weekend.
"Importance of welfare support and good communication stressed."
As of 10pm on Saturday, 23,000 households across the north and north-east of Scotland were without power, with SSEN saying attempts to reconnect them would be "likely to extend across multiple days" with customers being told to consider making "alternative arrangements".
The agency said it had moved to "red alert status", with director of distribution system operations Richard Gough saying: "Whilst our teams have made good progress and have restored power to the majority of customers affected by Storm Malik, due to the extent of damage caused, alongside the likely impact of Storm Corrie, we expect the full restoration of customer supplies from both storms to extend across multiple days."
Deputy First Minister John Swinney said in a statement on Saturday up to 20,000 customers could be without power overnight.
"The Scottish Government's resilience committee will continue to monitor the situation overnight and into tomorrow, and keep Ministers fully updated," he added.
"We will remain in close contact with local authorities and the emergency services to ensure people in the affected areas receive the latest information, advice and support where needed."
The Met Office has warned Storm Corrie could bring gusts of up to 90mph.
Forecasters said: "The intense area of low pressure will move eastwards across Scotland on Sunday, continuing across the North Sea in the early hours of Monday.
"Corrie will bring gusts of 70-80mph, potentially even up to 90mph in exposed coastal locations and mountainous areas of Scotland, in the late afternoon and into Sunday evening."
