Nepalese police said Thursday that dozens of people remained unaccounted for after Tuesday's peak hiking season storm -- sparked by Cyclone Hudhud -- that defied favorable weather predictions.

Ganesh Rai, the police official in charge of recovery efforts, said rescuers hampered by poor communications, had evacuated 43 stranded trekkers, including Hong Kong and Israeli visitors airlifted to Kathmandu with frostbite.

But, more than 100 other trekkers remained out of contact, Rai said. Some 168 foreign tourists had been registered to hike in the popular Annapurna region. Its trekking route rises to elevations of up to about 5,400 meters.

Rai said "several Nepalese" could still be among those missing in the new snowfalls as deep as two meters.

So far, the bodies of four Canadians, two Israelis, one Pole, one Vietnamese, one Indian, one German and 11 Nepalese had been found, he said. The nationalities of three others were unknown.

'Worst' in memory

The Trekking Agencies' Association of Nepal said it had counted at least 85 trekkers who were still unaccounted for.

Association treasurer Gopal Babu Schrestha described Tuesday's weather event as "one of the worst mountaineering accidents I can remember."

Local officials said most bodies were found on the Annapurna circuit, which draws thousands every October, when conditions are usually favorable.

Rescuers on Thursday were also searching higher on Mount Dhaulagiri for two Slovakian mountaineers and three Nepalese guides, missing since an avalanche struck their camp on Tuesday night.

Alternative route also hit

In western Nepal, a search is under way for a 67-year-old Frenchman who fell into a river swollen by downpours also brought by the cyclone.

He was among a 10-member group of tourists heading up a scenic route near Mount Manaslu that was developed as an alternative to the crowded Annapurna circuit.

Three yak herders also died in Naar village of Manang district.

April disaster on Everest

This week's fatal weather follows the deaths of 16 Nepalese sherpa guides in an avalanche on Mount Everest in April. That disaster prompted an unprecedented shutdown of the world's highest peak.

More than a tenth of the nearly 800,000 tourists who visited Nepal in 2013 went hiking or mountain climbing.

Adventure tourism generates key revenue for the cash-strapped nation, amounting to 4 percent of its gross domestic product.
