While the official figure of the death toll stood at 35, more reports of deaths are pouring in.
The incessant rainfall that hit the district on Tuesday night triggered massive landslides all across the hills and swept away several houses.
Two NDRF and NDMA teams are working at the landslide site, besides the SSB and state national disaster teams.
Prime Minister Narendra Modi expressed pain over the loss of lives and announced a compensation of Rs 2 lakh each to the families of the deceased.
He directed Minister of State for Home Kiren Rijiju to go to the locations to take stock of the situation. A team from NDRF is extending all possible support, Modi said.
"Deeply pained at the loss of lives due to the landslides in Darjeeling district. Condolences to the families of the deceased," he tweeted.

West Bengal Chief Minister Mamata Banerjee announced that a compensation of Rs 1.25 lakh will be given to those who are injured in the landslide and a compensation of Rs 4 lakhs will be given to the family of those deceased.
The National Highway - 10 has been cut off, as a result of which hundreds of tourists are stranded at Darjeeling.
"The state administration has swung into action and the rescue operations have begun. Border force is also helping in the rescue operations. Continuous rains are stalling the rescue operations," said Binay Tamang, Morcha Leader.
