Monsoon conditions initially brought heavy rainfall, thunderstorms, and warnings of flash floods and landslides to Nepal and the Indian state of Nagaland. Authorities in Nepal warned that weather in hilly and mountainous provinces could impact agriculture and transport.

Subsequent reports highlighted specific disaster risks, including a massive landslide in the Nepal-China border region caused by a glacier collapse. This event potentially created a temporary dam that burst, resulting in a sudden surge of water and sediment. In Japan, concerns were raised regarding the risk of catastrophic debris flows in Hidaka River Town due to steep cliffs and the potential for landslides triggered by rain or earthquakes.
