The Met Office issued amber "be prepared" warnings of heavy rain for Grampian, the Western Isles, Tayside, Fife and Central Scotland today.
In Fife a woman and her dog had to be rescued from a car after it was stuck in about 3ft of water in Colinsburgh late last night while another driver needed help from the fire service after a similar incident in Elie.
The A92 in Dundee has been closed due to flooding while traffic was said to be slow on roads in the Strathclyde area and the Lothians because of surface water. Roads in Grampian were also affected by flooding and surface water.
Transport minister Keith Brown said: "Just weeks after the first major storm of the autumn, the transport network is braced for another major challenge. Our operating companies are closely monitoring the situation and are ready to deal with any weather-related issues that arise.
"A wide range of agencies and organisations are poised to react quickly to the alerts and activate their response plans for the potential impact of heavy rain. The travelling public also have a key role to play. The Traffic Scotland website, variable message signs and traffic internet radio are being used to provide up-to-date information, allowing them to plan and amend their journeys accordingly."
