John Swinney’s comments came after he chaired a meeting of the Scottish government on storm resilience on Thursday evening.
The Met Office has issued a yellow warning for snow covering much of the Scottish mainland. This went into effect today at 3am and should be canceled Friday at 6pm.
Travel is likely to be affected and the forecaster warned that vehicles and passengers could be stranded on the road due to heavy snowfall. They also involve the delay or cancellation of rail and air travel.
Speaking to BBC’s Good Morning Scotland, Mr Sweeney said: ‘The weather conditions are obviously challenging with very heavy snow during the night.
“This was a forecast, and the trunk road companies and our local government partners were doing extensive sandblasting overnight to try and make sure the journey was road-stable this morning.
“Obviously there are a few problems in different parts of the country, but there are people who are very quick to solve these problems and try to solve them, but undoubtedly the advice that was given last night about people checking the conditions before traveling is advice to be observed today under all circumstances, given the amount of snow that has now fallen.”

Asked if the measures being taken across networks are proportionate, Mr Sweeney said: “We have a much more complex amount of information available to every member of society.
“Where we have to be careful is that the warnings are proportionate to the conditions we are facing.
“The amber warning, for example, required ScotRail to cancel all services the other day, and when you looked at the damage to the network, I saw that this is a proportional decision that ScotRail made, since I would not want the train to be hit by the wreckage, which lying around.”
Mr Sweeney said extensive preparations are underway and resources are available should any welfare issues arise.
The Deputy First Minister confirmed that the storm followed the path that the Scottish government modelers had predicted, causing destruction.
He said: “Snow has swept across the country and there will be heavy snow for most of the day.
“In terms of preparation, it is obvious that all the companies operating the main roads were involved, and last night they had their own plans.
“Energy companies are also prepared for the impact of the other part of the forecast, which was about strong winds, in the event of a power outage.”
Mr Swinney said southern Scotland was of “particularly localized concern” where coastal flooding is predicted to the southwest around Dumfries and Galloway due to strong winds in the Irish Sea and the Solway Firth.
“Obviously one has to be very careful in coastal situations in the southwest.” Deputy Prime Minister said.
