Flash flood washes away quarters, bridge.
A burst of intense rainfall over Arunachal Pradesh's Lower Subansiri and Keyi Panyor districts triggered flash floods, inundating villages, damaging homes and agricultural land, and washing away critical infrastructure.

According to information released by the Meteorological Centre in Itanagar, Yazali in Lower Subansiri district recorded 72.8 mm of rainfall in the 24 hours ending Tuesday morning. However, officials noted that the majority of this rainfall fell within a short three-hour window between 6 am and 9 am, leading to a rapid rise in river levels and overwhelming local drainage systems.

The sudden deluge caused flash floods in Luksin village and Yiyee-I and Yiyee-II villages under Toru Circle. Residents reported that floodwaters entered homes and swept through agricultural fields shortly after 6:30 am.


Initial damage assessments indicate that the house of Dukhum Adi in Luksin village and several other structures suffered damage. Standing horticultural and agricultural crops, including pineapple, banana and orange plantations, were also affected. Authorities said detailed reports are still being compiled.

Yiyee village was among the worst-hit areas, with floodwaters inundating large sections of the settlement. Local residents were safely evacuated and shifted to neighbouring households. No casualties have been reported so far.

The flooding extended beyond villages. Heavy rainfall and rising river flows caused significant destruction at the NEEPCO Colony in Posa, Yazali, in Keyi Panyor district.

Preliminary reports indicate that 15 residential quarters were destroyed, while a major highway bridge was washed away, disrupting connectivity in the region.

Meteorologists say the flash floods were triggered by an intense cloudburst-like rainfall event rather than prolonged rain over several days. When a large amount of rain falls within a short period, especially in the steep terrain of the Eastern Himalayas, water rapidly runs off mountain slopes into streams and rivers.

This sudden surge can lead to flash flooding even when the total daily rainfall is not exceptionally high.

The India Meteorological Department has warned that the combination of saturated soils, swollen rivers and continued monsoon activity could keep the risk of flooding and landslides elevated across parts of Arunachal Pradesh in the coming days.

Authorities have urged district administrations and line departments to remain on alert and take precautionary measures. Disaster management agencies are monitoring river levels closely as assessments of the damage continue.
