The Assam government has issued a high alert after extremely heavy rainfall and flash floods were reported in Arunachal Pradesh’s Lower Subansiri district, potentially impacting several districts of Assam downstream.

According to information received from Guwahati’s Regional Meteorological Centre and the Meteorological Centre in Itanagar, Lower Subansiri’s Yazali recorded 72.8 mm of rainfall during the last 24 hours, mostly between 6 a.m. and 9 a.m. on Wednesday (June 24, 2026).

“The high volume of rainfall resulted in flash floods and a substantial increase in river discharge in the upper catchment areas,” an Assam government statement said.

Train movement on the Trans-Harbour line was resumed this morning following a brief operational snag caused by soil erosion beneath the tracks due to the recent downpour in the city. The rains, happening in spells since Tuesday (June 23, 2026) evening, have resulted in the cancellation of 24 trains and ongoing speed restrictions between Turbhe and Vashi.

Central Railway, in an official update, stated, “Due to a track damage incident at the Trans Harbour line of Mumbai Local, 24 trains have been cancelled till now. Though the traffic is resumed in the affected portion after repairing, speed is limited due to caution in the affected portion of the trans harbour line between Turbhe and Vash.”

The incident occurred amid heavy rain that lashed Mumbai on Tuesday (June 23, 2026) and Wednesday (June 24, 2026), causing widespread waterlogging in several low-lying areas and leading the India Meteorological Department (IMD) to issue an Orange Alert for the region.

An under-construction retaining wall collapsed due to the downpour, and a large amount of water inundated low-lying residential areas in and around the colony, he said.

A day after the monsoon’s onset in Mumbai, heavy overnight rain disrupted suburban train services, caused waterlogging in low‑lying areas, and left commuters stranded.

Heavy rains lashed Maharashtra’s Thane and Palghar districts over the last 24 hours, triggering a landslide at the scenic Malshej Ghat and leading to dozens of complaints of tree falls, officials said.

A minor landslide was reported on Tuesday (June 23, 2026) evening along the vital Malshej Ghat stretch, which connects Thane and Pune districts, Thane’s Resident Deputy Collector Sandeep Mane said.

The incident occurred between the “wash point” and “umbrella point” at the ghat between 6 pm and 7 pm on Tuesday (June 23, 2026), according to district disaster management authorities.
