The Department of Hydrology and Meteorology has requested the public to adopt special precautions from Oct 4 to 6.

The department has warned of a high possibility of sudden flooding in small rivers of Bagmati, Koshi, and Madhes.

According to the department, a low-pressure system developed in the Bay of Bengal is expected to move inland from Odisha, India, towards central India. As a result, monsoon winds are predicted to enter Nepal, becoming active mainly in Koshi, Madhes, Bagmati, Gandaki, and Lumbini Provinces from Oct 3 to 6.

Based on current analysis, water levels in the Narayani, Bagmati, Kamala, and Koshi rivers, along with their tributaries, are likely to rise significantly and may reach danger levels.

Smaller rivers and streams flowing through the Mahabharat and Chure regions of Koshi, Bagmati, Gandaki, Lumbini, and Madhesh Provinces also face a risk of sudden surges. As the monsoon has not yet withdrawn from Nepal, the department said it is continuously monitoring potential adverse weather and flood conditions.

The public has been urged to stay updated through the department’s website, social media, toll-free service 1155, and other official channels to take necessary precautions.

The department has also appealed to all disaster risk reduction agencies and the general public to remain prepared. Risks such as floods, inundation, landslides, erosion, and disruptions to road and air transport may occur during this period.
