Disaster management officials in Khyber Pakhtunkhwa province, where 51 people have died since the downpour began Saturday night, said bad weather was hampering the rescue and relief operation.
"Death toll has been risen to 51, at least 150 houses have been destroyed," an official of the Provincial Disaster Management Authority told AFP, requesting anonymity as he was not authorised to talk to media.
Latifur Rehman, a spokesman for the Authority, told AFP that rescue workers had not been able to reach three affected districts in the far-flung mountainous north of the province.
Rehman said they had received reports that at least 180 houses had been destroyed in those areas.

"We need to get bodies and the injured out from under the rubble and provide food and tents to the survivors," Rehman said, adding that four truckloads of supplies had been sent to affected districts.
"All roads leading to villages and other areas have been blocked... There is no movement at all," Khalid Khan, a courier company owner in Shangla district of Khyber Pakhtunkhwa, told AFP, adding that local hospitals lack the facilities to deal with the injured.
At least ten people, including five children, died there when two houses were buried in a landslide caused by the rains, Raja Moazzam, a spokesman for local disaster management authority told AFP.
