Police are concerned for the safety of a woman reported missing in Westport last Friday.
Acting Senior Sergeant Paul Watson said they were continuing to search for Leanne Ryall.
The 50-year-old was last seen walking south along Cobden St towards Derby St, in the West Coast town, about 9am last Friday.
Mr Watson said police believed Ms Ryall was still in the Westport area, but they were not ruling out the possibility she might have left.
He said an extensive land-based search was carried out over the weekend, and a drone was also used to search bush areas and tracks.
Ms Ryall is about 161cm tall, of solid build and has short wavy red-brown hair.
