Search and Rescue teams are facing challenging conditions, including icy wind gusts and deep snow, as they continue to search for a missing walker in Mt Field National Park.
The search effort is being focused on the Tarn Shelf area, where knee to waist-high snow is being encountered in some areas.
Tasmanian man Daryl Fong, 30, was on a day hike in the Mt Field area at the weekend but his last known contact was about 3am on Sunday when he texted a friend, advising that he intended to seek shelter and camp in the park overnight.
A search has been under way since late Monday, when the alarm was raised.
Additional resources were deployed this morning, involving Tasmania Police Search and Rescue officers, SES search and rescue volunteers, two Ambulance Tasmania wilderness paramedics and the Westpac Rescue helicopter crew.
Police have released a photograph of Mr Fong as part of a call for information to anyone who may have seen him at the weekend, or since.
Mr Fong is believed to be wearing clothing similar to the image released.
Anyone with information about Mr Fong's movements at Mt Field, or who may have seen him in the national park, is asked to contact Bridgewater Police on 6173 2010.
