Residents of Dundee, Angus and an area of Perthshire have been warned to expect flooding this evening.
The Scottish Environment Protection Agency (Sepa) has issued a flood alert for Dundee and Angus, warning that “fast responding” rivers and other watercourses could lead to properties and roads being affected.
A more severe warning has been issued for the Bridge of Ruthven to Leitfie area of Perthshire near the River Isla, which is expected to surge overnight.
Flooding is expected from Wednesday evening into Thursday morning as a result of “heavy and intense” rainfall.
A Sepa statement accompanying the Perthshire warning said: “A flood warning has been issued for Bridge of Ruthven to Leitfie.
“A band of heavy and intense rainfall will affect this area during Wednesday evening and into Thursday morning. This will cause the River Isla to rise overnight.
“There is a risk of flooding to low lying agricultural areas adjacent to the River Isla.”
On the Dundee and Angus alert, Sepa added: “Heavy rainfall over higher ground is expected overnight Wednesday and early Thursday morning which has the potential to result in some localised flooding from surface water and fast responding watercourses and rivers.
“Potential impacts lasting into Thursday are likely to include travel disruption where the heavier rainfall occurs and localised flooding to low lying land, roads, isolated sensitive properties.
“Remain vigilant and remember, it is your responsibility to take actions which help protect yourself and your property.”
