A deluge swamped Tayside and Fife with more rain expected over the course of the week.
Although the rain eased off later on Wednesday evening, the Met Office warned this week’s T in the Park could turn into a mudbath with intermittent showers expected over the weekend.
A spokesman said, “The rain is gradually moving north and so it should begin to clear on Wednesday night. There will be showers at T in the Park, but it won’t be like the six hours of persistent rain we saw today.”
Wednesday’s downpour flooded parts of the Kingsway, Dundee’s busiest road, while other streets including Dudhope Terrace and Dura Street were flooded, as were parts of Broughty Ferry.
The Lidl supermarket in Dura Street was forced to close after being flooded.
A spokesman said, “We had teams pumping out water most of the day and if there is a break in the weather we hope to open again on Thursday.”
A police spokesman said, “Anyone who is travelling should allow plenty of time for their journey, reduce their speed and drive according to the conditions.
“Drivers should slow down approaching standing water to avoid risks of aquaplaning.”
The Scottish Environment Protection Agency (SEPA) issued flood alerts for all of Tayside.
The agency said river levels were expected to rise and that all urban areas would be at risk of surface water.
A spokesman said, “Due to heavy rainfall that has already fallen and is forecast for later during Wednesday, river levels in the Tayside alert area are expected to rise, which could lead to some flooding issues.
“The Earn, Almond and Isla catchments are particularly at risk of potentially high river levels, leading to possible flooding of low lying agricultural land.”
As much as 60-70mm or rainfall was expected in some parts of Tayside and Fife. An inch of rain fell on St Andrews alone.
Thunderstorms are expected over the next few days.
The heavy rain did not affect traffic on the Tay Road Bridge and staff at Dundee Airport confirmed that all flights leaving and arriving in the city were operating as normal.
