Thirty-one people were still missing and 96 people were injured across the Himalayan nation, police said on Monday.
Many of the deaths were in the capital, Kathmandu, which received heavy rainfall, and much of southern part of the city was flooded.
At least three buses stuck in traffic jam were buried by a landslide that killed three dozen people at a point on the highway about 16km from Kathmandu.
Because of the blocked road, people in the buses and other vehicles were sleeping when the landslide buried the vehicles.
