Drivers in Edinburgh and the Lothians are being urged to use caution after Scotland was hit with torrential rain overnight.
And tomorrow (Sunday) high winds are expected to affect major bridges including the Forth Bridge.
Widespread warnings over surface water were issued late on Friday night by Traffic Scotland.
They cover all routes in Edinburgh, Glasgow, South Lanarkshire, North Lanarkshire and Fife for today (Saturday).
There are no weather alerts in place for Scotland at the moment.
But heavy rain and the expected winds will make driving conditions more challenging.
