Ten more people were missing and the number of dead looked set to climb as large parts of the country were under water, officials said.
Around 600 tourists, including 200 Indians, are stranded in Nepal's Chitwal town because of widespread flooding and landslides caused by heavy rain, unidentified officials said, according to PTI.
The Home Ministry has appealed to the people to shift to safer areas.
Flash floods and landslides triggered by heavy rains have left more than 30 people dead in Nepal in the past 24 hours, authorities said on Saturday. Flood waters had entered the hotels in that area, according to media reports.
Numerous people being rescued from the hotels are tourists.
The flooding and landslides have cut communications and electricity in many affected areas.
Security forces are struggling to provide rescue and relief to the affected as portions of highways have either been swept away, collapsed or are obstructed by debris from landslides in many places. He also urged the population in the areas affected to remain calm.
Meanwhile, Nepal Cabinet held an emergency meeting during which Prime Minister Sher Bahadur Deuba ordered the local district administrations to intensify the rescue and release activities.
Issuing a statement following an emergency meeting on Sunday, the human rights watchdog appealed the Nepal government, security agencies, national and worldwide organizations to expedite the rescue and relief operation in flood and landslide affected settlements.
Almost 100 people died previous year in Nepal during the rainy season, which typically begins in late June and lasts until the end of August. Officials have warned that the death toll could increase because at least 17 people are still missing.
