David Faichney, SEPA’s Hydrology Duty Manager, said:
A brief period of relative calm is forecast for today with only occasional rainfall over parts of eastern Scotland and some snow on higher ground in Tayside, Angus and Grampian. This respite however is due to be short lived, as a more persistent band of rain arrives overnight tonight, moving from the South West to cover central and northern regions by Thursday morning.
"This weather front is forecast to move slowly across the north east and out to the North Sea on Friday morning. The Met Office are forecasting over 25mm of rain across the region with some areas seeing up to 50mm throughout the course of this feature.
"With the saturated nature of the ground and the currently high river levels we expect to see some significant flooding impacts in parts of Tayside, Angus, Aberdeenshire and eastern Moray. This is likely to include flooding of properties, roads and further disruption to infrastructure and travel. The main areas at risk include the Rivers Isla, the lower reaches of the River Tay and smaller watercourses in Angus and southern Aberdeenshire.
"Whilst the focus is in the NE of Scotland, rain will also be very heavy across Fife and the eastern part of the Scottish Borders and minor impacts are likely for these areas too.
