Police are looking for a missing woman from the Hutton le Hole area who has not been seen since Friday afternoon.
57-year-old Evelyn Bumby who lives just outside the village was reported missing on Saturday morning.
Police say her disappearance is out of character and she does not have her essential medication with her.
Police officers, police dog handlers, a police helicopter and search and rescue volunteers from Scarborough and Ryedale and Cleveland Mountain Rescue Teams are involved in the search which at this stage is being centred in and around the Hutton le Hole area.
Inspector Andy Everitt of Ryedale Safer Neighbourhood Team, said: “We are growing very concerned for Evelyn’s safety.
"I am appealing to anyone who may have seen her to contact the police.
"I also urge residents to check their outbuildings, sheds and garages in case Evelyn has taken shelter in them."
