Brechin residents are being evacuated as the town prepares for Storm Babet.
Angus Council has identified around 335 homes which have been asked to evacuate for their own safety.
Emergency shelters are being set up at Brechin Community Campus, Forfar Community Campus and Montrose Sports Centre from 3pm.
Those impacted are being asked to take sleeping bags, medication and other supplies.
A spokesman for Angus Council said: “Over the past few days, resilience colleagues have been working with Sepa to identify areas at most risk of flooding, due to the unprecedented level of rain that is expected to fall across Angus.
“As a result, we have identified approximately 335 homes in Brechin, and an additional 87 homes in Tannadice and Finavon where residents will be asked to evacuate for their own safety.”
Rest centres
“In preparation of such a situation, rest centres have been set up at Brechin Community Campus, Montrose Sports Centre and Forfar Community Campus which will open at 3pm to support those affected and we are working closely with colleagues from Angus Health and Social Care Partnership to identify vulnerable residents who will require additional support.”
A rare red weather warning is in place across parts of Aberdeenshire, Angus and Tayside.
Sepa flood unit manager Pascal Lardet told the BBC: “We will try to anticipate as much as we can.
“There’s a specific focus in the Brechin area which has flooded in the past.”
Flood defences
Brechin’s £16.3m flood defence scheme officially opened in 2016.
It was built to protect parts of the town from the River South Esk during periods of severe flooding.
Residents in the River Street area endured decades of flood misery when the river burst its banks.
And a year into the construction project, locals had to be evacuated from their homes when Storm Frank struck in 2015.
The Brechin scheme was one of the biggest civil engineering projects of its kind in Angus at the time.
It includes a flood wall along River Street and three submerged pumping stations along the stretch.
