The Met Office has issued rain and thunder warnings lasting 54 hours in Dundee, Perthshire, Angus and Fife.
People in the whole of Courier Country are braced for more thunderstorms and torrential rain, a day after several routes were hit by flooding.
As the clean-up continued today, the Met Office issued two yellow warnings for Courier Country.
A yellow warning for rain is already in place for the whole of Friday, with heavy showers or thunderstorms potentially bringing disruption.
Now the forecaster has issued a warning of thunderstorms throughout the day on Saturday until Sunday at 6am, meaning the local area is subject to 54 hours of weather warnings.
The forecaster said local properties would be at risk of flooding and lightning strikes on Saturday as “slow-moving, heavy” downpours batter the region.
It said driving conditions could become difficult and that there may be some disruption to travel.
A number of roads became impassable yesterday as sudden downpours struck.
A section of Stannergate Road in Broughty Ferry was closed as manhole covers gave way and Scottish Water was called to deal with the issue.
In Fife, residents were rescued by boat as homes were evacuated in Rosyth.
Police were at the scene to ensure members of the public did not approach the area while it was cleared by engineers.
A number of manhole covers were lifted due to the huge volume of rain.
A Scottish Water spokeswoman said: “As a result of heavy rainfall overnight, areas within the vicinity of Broughty Ferry Road, Dundee are experiencing some surface level flooding.
“During such weather events, drains and water courses can struggle to cope with the amount of surface water from buildings, footpaths and roadways.”
