Lost Tas bushwalker remains on mountain

A lost bushwalker has spent another night on Tasmania's Cradle Mountain with poor weather preventing her rescue.

The Northern Territory woman was found on Tuesday morning with an injured thigh after she used a satellite phone to call for help the previous afternoon.

She stayed with five members of the police search and rescue team at the Waterfall Valley Hut overnight.

Police say she might not be able to be rescued until Thursday, as a helicopter hasn't been able to get to the area.

Difficult weather conditions are set to continue.

"It may well be that she has to bunker down for the night and we'll try again tomorrow or indeed Thursday to walk her out," Inspector Shane LeFevre said on Tuesday.

The woman was suffering from hypothermia, police saying she wasn't prepared for Tasmania's cold.

The state is expecting strong winds, freezing temperatures and snow down to 100 metres above sea level on Wednesday.
