Almost all of the victims were in Panjshir province, approximately 150 kilometres (90 miles) north of the capital Kabul, acting governor Abdul Rahman Kabiri told AFP.
The avalanches came after two days of heavy snow destroyed more than 100 homes in the province and blocked main roads, making it difficult for rescue workers to reach the stricken villages.
“Ordinary people and government employees are using shovels and bare hands to rescue those who are still trapped under the snow,” Kabiri said, warning that the toll could rise without emergency help.
“We have gathered 300 people to help with the rescue, but we don’t have the equipment we need,” he added.
As temperatures plunged well below freezing, workers continued to toil into the night to rescue at least 28 people still believed to be trapped in their houses buried under the snow.
Around 30 people were also suffering from frostbite and other injuries after being rescued, the acting governor said.
“We will continue the rescue operation throughout the night,” Kabiri added.
One hundred have been killed in Panjshir province, while a further 11 people lost their lives in the provinces of Bamyan, Badghis, Nangarhar and Laghman, officials said.
Abdul Rahman Kalantari, head of disaster response at the Afghan Red Crescent Society, confirmed the heavy death toll and said they had already dispatched health teams to Panjshir.
President Ashraf Ghani in a statement expressed his sorrow at the deaths and said he had ordered Afghan authorities to provide urgent assistance to those affected.
Earlier in the day, Mohammad Aslam Sayas, the deputy head of the Afghan disaster management authority, said rescue teams were being dispatched to areas affected by the snowfall.
Deadly avalanches are common in Afghanistan’s mountainous areas in winter. One in the remote far northeast in 2012 left 145 people missing, presumed dead
In 2010, another avalanche killed 165 people in the high-altitude Salang Pass, which runs through the Hindu Kush mountain range that connects capital Kabul to the north.
Large parts of the north of Afghanistan have experienced heavy snowfall over the last 48 hours.
Parts of Kabul were hit by power cuts after snowstorms and avalanches damaged power cables in the Salang Pass, which officials said remained closed to traffic on Wednesday.
Despite the billions of dollars in aid from the international community after the collapse of the Taliban in 2001, Afghanistan remains among the world’s poorest nations after decades of conflict.
Rescue efforts after disasters such as avalanches and flash floods, which often hit as snows melt in the spring, are frequently hampered by lack of equipment.
