According to the Department of Hydrology and Meteorology (DHM), the system is gradually moving eastward and is expected to remain active until Sunday, bringing moderate to heavy rainfall in many areas.
Heavy Rainfall Predicted Across Provinces
Senior Hydrologist Binod Parajuli, from the Flood Forecasting Division, stated that rainfall continues in the eastern parts of Bagmati, Madhesh, Gandaki, and Lumbini Provinces, along with Koshi Province’s eastern belt. “This system will stay active until tomorrow, and the rain is likely to intensify, especially during the evening and night,” he told Nepal News Bank.
