Most of the deaths were reported from the central and eastern provinces of the war-shattered South Asian nation, including Parwan, Maidan Wardak, Daykundi and Logar, where torrential rain triggered flash floods and caused houses to collapse in rural and mountainous regions, the authority said.
Conditions remained "unstable" in parts of the country on Monday, with continued risk of further rain and flooding in some areas, it said.
"Twenty-two people were killed, 32 injured and 241 houses damaged in flooding and other weather-related incidents across 13 provinces over the past two days," an NDMA official, who did not want to be named because he was not authorised to speak to the media, told Reuters.
Afghanistan is prone to natural disasters, and the United Nations lists it among the countries most vulnerable to climate change.
With international aid, which formed the backbone of the government's finances, slashed since the Taliban seized power in 2021, the country has been struggling to cope.
A United Nations Development Programme report in November said earthquakes, floods, and drought had destroyed 8,000 homes in Afghanistan in 2025 and strained public services "beyond their limits".
At least 17 people, including 14 children, have been killed and 56 others injured after heavy rains triggered roof and wall collapses in parts of Khyber-Pakhtunkhwa since March 25, according to a report released by the Provincial Disaster Management Authority (PDMA) on Monday.
