Three persons went missing after heavy rains triggered flash floods in Arunachal Pradesh’s Keyi Panyor district on Wednesday morning, PTI reported.

They were at the North Eastern Electric Power Corporation Limited project colony near Poosa under the Yazali circle, where an under-construction retaining wall collapsed due to the downpour, the news agency quoted State Disaster Management Secretary Dani Sulu as saying.

The flash floods inundated low-lying areas and damaged at least 18 houses.

The rains also triggered landslides along a national highway, disrupting traffic and leaving several persons stranded.

The government in neighbouring Assam has issued a high alert, warning of possible impacts of the flash floods in districts in downstream areas, PTI reported.

Mumbai records heavy rain

A day after the monsoon arrived in Mumbai, heavy overnight rainfall disrupted suburban train services and caused waterlogging in several low-lying areas, PTI reported.

Parts of the city recorded more than 200 mm of rainfall in the 24 hours ending at 8 am on Wednesday.

The IMD had issued a red alert for Mumbai and Palghar in the early hours of Wednesday, warning of thunderstorms, lightning, intense to very intense rainfall and winds of 40-60 kmph.

The alert was later downgraded to orange, though moderate to intense spells of rain are expected to continue in Mumbai, Thane, Raigad, Palghar and Sindhudurg districts.

Monsoon advances further

The southwest monsoon has advanced into more parts of Gujarat, Madhya Pradesh and Maharashtra, and some areas of Chhattisgarh and Jharkhand, the India Meteorological Department said on Wednesday.

Conditions remain favourable for its further advance into the remaining parts of Chhattisgarh and Jharkhand, more areas of Gujarat, Madhya Pradesh and Bihar, parts of Uttar Pradesh, and parts of Uttarakhand over the next two to three days.

However, heatwave conditions are likely to continue over eastern Uttar Pradesh for the next four to five days and over northeastern Madhya Pradesh and Bihar for the next two to three days.
