The Scottish Environment Protection Agency (Sepa) has issued 25 flood warnings and 16 flood alerts around the country, warning of a risk of coastal flooding.
Sepa said: “The Met Office has forecast strong and sustained winds from Monday morning, January 13, through much of the week.
“Combined with naturally high tides next week, the sustained winds will create an unusual and dangerous combination of tide, storm surge and inshore waves.
“There is therefore a risk of coastal flooding to all Scotland’s coastal areas. The highest risk is around high tides from midday Monday through to Tuesday afternoon.
“There is a flooding risk to coastal road and rail routes and coastal communities right around Scotland’s coastline.”
Restrictions were placed on several bridges, with the Cromarty, Dornoch, Skye and Kessock bridges among those closed to high-sided vehicles.
Some visitor attractions were also affected, with Dumbarton Castle and Dundonald Castle shut due to the weather.
