The storm brought snow, with the people in South Lanarkshire were seen clearing their driveway, and high winds caused disruption in the road as they toppled trees.
NS Met Office issued a yellow weather warning for snow and wind, with forecasters warning gusts of up to 80 mph on the west coast and up to 65 mph around the east coast.
It warns of 2-5 cm snowfall in some areas and 10-20 cm in the southern highlands and Highlands.
The storm threatens to cause further disruption to areas of the country that have been without power for days after Hurricane Arwen.
The Scottish and Southern power grids said they had put staff on alert in the areas they believe could be hardest hit to try to minimize any disruption to the grid.
As the storm moved across the country, the Met Office recorded a gust of 68 mph in Machrihanish, near Campbeltown in Argyll.
Schools in Dumfries and Galloway were forced to close because of the weather. The council said Stranraer Academy was closed after winds damaged its roof structure, and Drummore School was closed because of fallen trees.
Other schools have also been closed, including Sheuchan School and Raphad School, because of Storm Barra.
High winds have also brought disruption to travel. Earlier, on Tuesday, a tree fell on the A702 near Coulter in South Lanarkshire, blocking the road.
Rod Dennis, a spokesman for RAC Breakdown, urged people to drive to road conditions.
“As Cyclone Barra hit the UK, motorists needed to really have the intelligence to stay safe. We urge drivers to stick to the main roads where possible, to slow down to suit the conditions, and to be especially careful when overtaking vehicles overhead to avoid swerving,” he said.
Snow has slowed M74 and M8 traffic, and Network Rail Scotland said a fallen tree blocked tracks on the West Coast Mainline, north of Lockerbie, and damaged overhead lines.
And Scot Rail has also canceled service and warned passengers of delays after the operator was forced to slow down trains because of the weather.
It canceled Tuesday services between Stranraer and Girvan, and from 3pm will run only a limited service between Dundee and Aberdeen.
It also said trains would stop from 4pm on lines between Inverurie and Montrose, and from 5pm trains between Inverness and Elgin would be cancelled.
North East London Railway also announced a series of flight delays and changes due to weather.
A Department for Transport Scotland spokesman said: “The conditions caused by Cyclone Barra continue to have the potential to affect the backbone network, as well as other modes of transport.
“As always, we urge people to check the latest information before they depart, drive to conditions and follow Police Scotland Tour.”
Cyclone Barra, the second winter storm of the season, will continue to hit the UK tonight, with a yellow warning in Scotland ending at midnight.
Becky Mitchell, senior operational meteorologist at the Met Office, said: “Strong winds will continue across the UK this evening, bringing in around 40-50 mph and up to 65 mph at the coast. This can cause difficult travel conditions, some power outages and large waves at the coast.
“Rain and snow will cover Scotland after midnight, and winds will ease for most of the country. However, it will be windy in parts of south-west England and Wales, where the yellow wind warning remains in effect through Wednesday. ”
Along with warnings from the Met Office, the Scottish Environmental Protection Agency has also issued two flood warnings and 10 flood warnings for the country.
