Indian navy ships and helicopters searched in extreme weather and rough seas for 78 people still missing from a barge that sank off Mumbai as a deadly cyclone blew ashore this week.

Navy Commander Alok Anand said 183 people were rescued within 24 hours by the three ships and helicopters engaged in the operation.

A survivor told the New Delhi Television news channel that he jumped into the sea with his life jacket and was later picked up by the navy.

In another operation, a navy helicopter rescued 35 crew members of another barge, GAL Constructor, which ran aground north of Mumbai, a government statement said.

Both barges were working for Oil and Natural Gas Corp, the largest crude oil and natural gas company in India.

The company said the barges were carrying personnel deployed for offshore drilling and their anchors gave away during the storm.

Cyclone Tauktae, the most powerful storm to hit the region in more than two decades, packed sustained winds of up to 130 miles per hour when it came ashore in Gujarat state late on Monday.

The storm left at least 25 dead in Gujarat and Maharashtra states.

The Hindu newspaper tallied more than 16,000 houses damaged in Gujarat state and trees and power poles uprooted.

The cyclone has weakened into a depression centred over the south of Rajasthan state and adjoining Gujarat region, a statement by the Indian Meteorological Department said on Wednesday.

In Nepal, authorities on Tuesday asked mountaineers to descend from high altitudes because the storm system may bring severe weather.

Hundreds of climbers, guides and staff are on various mountains in Nepal, trying to climb the peaks this month when weather is usually most favourable in the high altitudes.

Nepal has eight of the world’s 14 highest peaks, including Mount Everest.

The Department of Tourism in a statement asked climbers and outfitting agencies to monitor the weather and stay safe.

In 2014, snowstorms and avalanches triggered by a cyclone in India killed 43 people in Nepal’s mountains in the worst hiking disaster in the Himalayan nation.

The snowstorms were believed to be whipped by the tail end of a cyclone that hit the Indian coast a few days earlier.

The blizzards swept through the popular Annapurna trekking route and hikers were caught off-guard when the weather changed quickly.
