RCMP in Yellowknife are seeking the public's help to find a mentally ill woman who has been missing since the weekend.

Angela Meyer, 21, was last seen on Saturday at around 1:20 p.m. MT outside her 54th Street home, police said in a release Monday.

Meyer was not wearing gloves or a hat at the time. Police say she has a mental illness and it's not known if she had brought her medication with her.

A ground search is underway for Meyer, who they are describing as an Inuit woman about five feet 10 inches in height and weighing about 230 pounds.

Police say she was last seen wearing a white Helly Hansen winter coat, black yoga pants, a black T-shirt, black socks and grey winter boots. Her fingernails were manicured with a black design on them, they add.

Anyone who has seen Meyer is asked to call the Yellowknife RCMP detachment.
