Despite dangerous weather conditions hampering search efforts, police remain optimistic Mr Bowman will be found alive and well.

The Westpac Rescue Helicopter was forced to turn back from the search for Mr Bowman late on Monday morning due to dangerous conditions.

Police said further attempts would be made once conditions improve.

Acting Inspector Phil Curtis said police information was that Mr Bowman was an experienced bushwalker who was well-prepared for his walk.

"The last information that his family had was that he was at a sheltered campsite," Acting Inspector Curtis said.

Acting Inspector Curtis said this contact between Mr Bowman and his family was about a week ago.

"We are concerned for his welfare, but we remain optimistic that Michael will be located alive and well," he said.

Mr Bowman had indicated his intention to walk in the Mount Cuvier region and was due to return on Saturday.

"Land crews have been assigned from Narcissus Hut to Cuvier area and surrounds and also from the Visitors Centre to Narcissus," Acting Inspector Curtis said.

"This is rugged terrain with no formal track. The search is being further hampered by the current weather event, with no mobile communication in the area.

"Police would like to thank those people who have volunteered to join the search, however the conditions are not suitable for unskilled volunteers."

Acting Inspector Curtis said the continuation of the search effort for Mr Bowman was being regularly assessed, taking into account a number of factors including the safety of rescue teams.

Police said it is believed Mr Bowman was carrying an Emergency Position Indicating Radio Bacon which has not been activated.

Mr Bowman is described as 180cm tall, of medium build, carrying a grey pack and wearing a red/orange jacket and dark coloured pants. He is thought to be using a yellow/mustard coloured tent.

Anyone who may have seen Mr Bowman in the Cradle Mountain - Lake St Clair National Park is asked to call police on 131 444.

On Monday afternoon police were alerted to another walker potentially suffering from mild hypothermia in the Petrarch Lake area, at the North-Western end of Lake St Clair, close to where they were searching for Mr Bowman.

The Brisbane man was rescued from the area by helicopter and returned to Derwent Bridge after activating a personal locator beacon.

"This man is an experienced bushwalker, but he experienced difficulties due to severe weather conditions," Acting Inspector Curtis said.

Emergency services will sweep huts at two Northern national parks on July 16 in response to a number of calls for assistance after several days of snow caused blizzard conditions in the areas.

Huts at the Walls of Jerusalem and Lake St Clair National Park will be the target, with walkers in the area given the option to be abandon their hikes and be removed safely, or continue to their original destination.

Tasmania Police Inspector Darren Hopkins said snowy conditions had been problematic for a number of bushwalkers.

"There is deteriorating weather for the rest of the week, that's why we are trying to get the helicopter in first thing tomorrow morning because that's where we think the window is for the weather," Inspector Hopkins said.

"We will sweep all the huts in the national parks ... to see if there are any walking groups that want to be removed for their own safety, plus it gives us an idea of who is in the park."

About 30 bushwalkers, including a school group, are believed to be in the alpine areas.

A father and daughter from Western Australia spent Monday afternoon attempting to reach Pelion Hut at Lake St Clair National Park after treacherous conditions forced them to stop hiking and set up camp.

The experienced bushwalkers were at Lake St Clair National Park about 4pm on Sunday, trekking near Kia Ora Hut, when they reported being cold and tired, so they set up camp about one-kilometre south of Pelion Gap.

The helicopter attempted to reach the pair but was hampered by the weather.

At 1pm on Monday, Lake St Clair was six degrees, but the feel-like temperature was minus three.

Inspector Hopkins said the father and daughter were communicating to a family member via a Garmin device.

"Once we speak to them tonight via their mother/wife we will determine whether they're happy to continue the next day or whether we move them out tomorrow morning," he said.

A NSW man and a Newtown man were rescued from the Walls of Jerusalem National Park near Junction Lake on Monday.

The experienced walkers were scheduled to complete their walk on July 15, but activated their EPIRB about 10.30am on Sunday when they realised they could not walk in the conditions and wouldn't reach their destination in a reasonable time.

The Westpac Rescue Helicopter searched for the pair, but was unable to reach them due to poor weather conditions.

About 5pm a search and rescue team attempted to walk to the location, but were forced to turn back because of the depth of the snow.

Three police search and rescue members were sent in about 2am, but they also found conditions too difficult to walk in and retreated.

A second attempt with the helicopter the following morning proved successful.

Inspector Hopkins advised anyone thinking of going into the alpine conditions to take the right equipment, including a quality tent, sleeping bag and clothing.

"Make sure you have an emergency device, and you're going with someone or have experience in the alpine of Tasmania," he said.

Bureau of Meteorology forecaster Matthew Thomas said overnight winds in the Central Pleateau would add to the chill people in the area were experiencing.

"We are certainly seeing some reasonable winds at the moment over the Central Plateau," he said.

Overnight rain was expected to wash away some snow from previous days, reducing the depth but increasing the amount of run-off water going into streams, therefore making stream crossing more problematic.

Mr Thomas said showers would ease on Tuesday, with the maximum temperature at Cradle Valley reaching six degrees and Lake St Clair topping seven degrees.

"We will see a front cross the state on Wednesday with showers increasing again, so precipitation will fall as showers ahead of the front, with snow possible once the front has passed," he said.

From Wednesday, rain and snow will fall with rivers expected to rise as a result.

Up to 20 millimetres of rain is predicted for Wednesday, with about 10 millimetres to fall as snow.

A cold front will cross on Wednesday and Thursday, with up to 15 centimetres of snowfall predicted across the two days.

"On Friday there will be another front crossing, and we will again see snow falling, and probably another 5cm of snow on Friday," Mr Thomas said.
