Devastating floods, landslides hit Arunachal; over 80 homes inundated in Upper Subansiri

Arunachal Pradesh is currently battling a severe monsoon crisis, as torrential rains over the past several days have triggered widespread flooding and landslides across multiple districts. A red alert has been sounded in numerous regions, including Kurung Kumey, East Kameng, Siang, Shi Yomi, Kra Daadi, Lower Subansiri, Upper Subansiri, Namsai, and Lohit, among others. Despite the extensive damage to infrastructure, no casualties have been reported thus far.

The worst-hit areas include the picturesque Ziro Valley, now submerged under floodwaters. Agricultural fields and paddy crops have suffered heavy damage as rivers and streams overflowed their banks. The overflow of the Sigin River has particularly impacted Daporijo in Upper Subansiri, where over 80 homes have been flooded, and vital roads and public facilities are underwater. The landslide-prone NH-13 between Raga and Daporijo has also been affected, disrupting connectivity.

In the twin capital cities of Itanagar and Naharlagun, floodwaters have inundated roads and low-lying areas, leading to disruptions in daily life. Locals have blamed unplanned urban development, especially the newly built Trans-Arunachal Highway, for aggravating the crisis. Blocked traditional drainage systems and unscientific landfills have worsened the situation.

A concrete bridge over the Buri Dihing River in Changlang's Magantong area is reportedly at risk of collapse due to rising water levels. Meanwhile, in Tezu (Lohit district), warnings have been issued for further heavy rainfall. Authorities continue to plead with residents to avoid risky behavior—such as fishing in flooded areas like Machawara Camp—especially with children, despite repeated warnings.

Emergency measures have been put in place. Deputy Commissioners of several districts have issued prohibitory orders, advising residents in vulnerable zones to move to safer areas. All relevant departments, including police, disaster response teams, and civil supplies, have been placed on high alert.

The Indian Meteorological Department (IMD) has forecast heavy to very heavy rainfall with isolated extreme events over Arunachal Pradesh until at least May 31, 2025. Thunderstorms accompanied by lightning and gusty winds are also expected. The rainfall is associated with a Low-Pressure System over Northeast India, contributing to an extended monsoon spell.

The IMD has also issued a Multi-Hazard Warning for the state. With the Brahmaputra River and its tributaries swelling in neighboring Assam, the regional impact of Arunachal’s rainfall is already being felt across Northeast India. While the IMD anticipates a marginal reduction in rainfall intensity, above-normal showers are expected to continue due to the advancing southwest monsoon.

Relief operations are underway, and authorities are closely monitoring the situation. The government has appealed to the public to remain vigilant, follow official advisories, and cooperate with emergency services to mitigate potential loss of life and property.
