Days of heavy continuous rainfall have caused a sharp rise in water levels in the Gandak River, which flows through the territories of Nepal and India. According to reports from local authorities, record water level readings have been recorded at several sections of the river throughout the entire history of observations. The heavy precipitation that triggered the flooding affected both the mountainous regions of Nepal and the plains of India's Bihar state, where the river flows into the Ganges. Authorities in both countries have begun monitoring the situation and have warned residents of riverside settlements about the possible threat of flooding. In the past, rises in the Gandak's water level have repeatedly led to infrastructure destruction, population evacuation, and damage to agricultural land in floodplain zones. Meteorologists attribute the current heavy rainfall to seasonal monsoon rains, which this year have proven to be particularly intense in the Himalayan region and adjacent plains. Emergency services are on high alert, and preparations are underway for the possible evacuation of residents from risk zones. The situation remains under the control of regional authorities, who are coordinating actions with neighboring countries as part of transboundary management of the river's water resources.
