The disaster has significantly impacted transport, resulting in damage to 19 major roads. Landslides obstructed all highways leading from Kathmandu, with the Prithvi Highway being the sole route partially reopened. Roads in central and southern Nepal, including essential routes such as the BP Highway, Mid-Hill Highway, and Araniko Highway, are currently experiencing partial blockages. Researchers from Nepal, India, Sweden, Australia, the United States, and the United Kingdom conducted an assessment of the impact of human-induced climate change on the likelihood and intensity of extreme rainfall, which resulted in significant landslides and floods. The analysis of the event concentrates on the most impacted regions in Nepal, specifically the provinces of Gandaki, Bagmati, Madhesh, and Koshi. The rainfall occurred at the conclusion of the monsoon season, a period characterised by saturated soils, indicating that the three days of intense precipitation were the primary contributors to the observed impacts. The maximum of the annual 3-day rainfall serves as the definition for the temporal event.
