Casualties due to floods, landslides, and rain-related incidents have been reported from Assam (9), Arunachal Pradesh (8), and Mizoram (6).

The downpour has severely affected road connectivity and infrastructure, damaged homes, and disrupted power supply, leaving thousands in distress.

Landslides claimed five lives in Kamrup Metropolitan district, while three people died in the floods — two in Golaghat and one in Lakhimpur.

More than 200 people from West Tripura and Khowai districts have been relocated to four relief camps after their homes were submerged due to continuous downpours.

Floods Worsen In Manipur, More Areas Submerged

Manipur is facing a second day of severe flooding, as continuous rainfall has caused rivers to swell and embankments to break across the Imphal Valley.

On Saturday evening, fresh breaches in the Imphal and Iril rivers led to new flooding in Ahalup Makha Leikai (Heingang constituency) and Khurai Konsam Leikai (Khurai constituency). These areas are now fully submerged, adding to several others already underwater.

Relief camps have been opened by the authorities. Although no casualties have been reported so far, most homes in the affected areas are flooded. With rain still falling, there are growing fears of more flooding.

Officials are urging residents in low-lying areas to stay alert and follow safety advisories.
