Police Scotland are appealing to residents in the Strichen area to check their outbuildings as enquiries continue to trace Seonaid (Shona) Bacon, 52, who has been reported missing.
She was last seen walking at around 12.10am today, Monday, April 3, in the Skelmanae area near to the A98 Fraserburgh to Banff road.
Inspector Kevin Goldie said: "It is out of character for Seonaid to not be in touch with family or friends and as time goes by we are increasingly concerned for her well-being.
"We are asking residents in the local area to please check any outbuildings, garages or sheds for signs that someone may have sought shelter there.
"Searches are being carried out in the local area including the use of a search dog and the Police Scotland helicopter.
"We are urging anyone who has information that could assist us to get in touch as soon as possible on 101."
Seonaid (Shona) is described as around 5ft 6ins tall with a slim build and short white hair. When she was last seen she was wearing a white dressing gown with blue and pink spots, black slippers and grey tracksuit bottoms.
If anyone has seen her or knows of her whereabouts they should contact police as soon as possible on 101.
