“The Scottish Government is in close contact with local authorities and the emergency services to ensure people in the affected areas receive the latest information and support where needed. I would urge everyone in the affected areas to exercise caution and follow the latest travel advice.
“I want to assure the public that we have strong and robust arrangements in place to manage and address weather-related resilience issues at a national, regional and local level. In the aftermath of Storm Arwen, we will review the preparations and response to ensure we learn from this most exceptional storm.”
