Heavy rain batters Tamil Nadu: flooding, power cuts hit 6 districts on 27 Oct
Synopsis
Six districts across Tamil Nadu are reeling from heavy rain that submerged roads, knocked out power for over 10 hours in Sivaganga, and drove Army teams to clear a landslide-hit hill road near Udhagamandalam — all while the weather department warns a Bay of Bengal cyclone is on course to intensify into a very severe storm, with landfall projected near Yanam on the Andhra Pradesh coast.

A cyclone in the Bay of Bengal is expected to intensify into a very severe cyclonic storm , with likely landfall between Bapatla and Visakhapatnam on the Andhra Pradesh coast.
The weather department forecast a gradual reduction in rainfall over Tamil Nadu over the next two days, with Chennai expecting partly cloudy skies.
Heavy rainfall disrupted normal life across several districts of Tamil Nadu on 27 October 2026, submerging roads, damaging infrastructure, and triggering power outages lasting over 10 hours in some areas, even as the weather department forecast scattered showers to continue over the Western Ghats districts and southern parts of the state. The disruption came as forecasters separately warned of a cyclone in the Bay of Bengal intensifying into a very severe cyclonic storm.
Flooding and Road Damage Across Districts
In Tirupattur district, roads in the Vayampattu area were submerged following heavy downpours, leaving motorists struggling to navigate waterlogged stretches and causing considerable inconvenience to commuters. In Coimbatore district, intense rainfall lashed Puliyamarathupalayam, Sulur, and Varapatti, with a tarred road in Puliyamarathupalayam suffering damage that disrupted access for road users.
In Kodaikanal, the rainfall substantially increased flow at the Silver Cascade waterfall, and water entered homes in the Thoppikanal area, severely affecting household activities and daily life. Army personnel were meanwhile engaged in clearing and repairing a landslide-affected stretch of the hill road leading to Udhagamandalam, with restoration work continuing through the day.
Power Outages and Civilian Hardship
Urban areas of Sivaganga experienced a power outage lasting more than 10 hours, compounding difficulties for residents already grappling with wet weather and inundated streets. In the Tharangambadi area of Mayiladuthurai district, students were forced to make the morning journey to school in driving rain, with many arriving drenched — a visible indicator of the scale of disruption to daily routines.
Cyclone Warning: Bay of Bengal Storm to Intensify
The weather department issued a warning that a cyclone tracking through the west-central Bay of Bengal was expected to intensify into a very severe cyclonic storm. The bulletin indicated a possible landfall along the Andhra Pradesh coast between Bapatla and Visakhapatnam, near Yanam. While the storm's projected track does not make direct landfall on Tamil Nadu, its outer bands are expected to continue influencing weather in the state's southern and coastal districts.
Weather Forecast for Tamil Nadu
For Tuesday, the weather department forecast light to moderate rain at one or two places across Western Ghats districts and southern districts, with predominantly dry conditions elsewhere. On Wednesday, isolated light to moderate showers were forecast over Western Ghats districts, with light rain possible in parts of southern Tamil Nadu.
Chennai was expected to see partly cloudy skies on Tuesday, with light to moderate rain possible in some localities — a relative reprieve following days of heavy downpours that left multiple districts dealing with waterlogging, damaged roads, and interrupted power supply. The broader forecast points to a gradual easing of rainfall intensity over the next two days across most of the state.
Point of View
The same waterlogging, the same multi-hour power failures that surface every October. What the district-by-district damage list obscures is a systemic failure in urban drainage and rural road resilience that no season of repairs has yet fixed. The more consequential concern, however, is the Bay of Bengal cyclone: its projected landfall on the Andhra Pradesh coast does not insulate Tamil Nadu, whose coastal and southern districts will likely absorb significant outer-band rainfall. Authorities would do well to front-run evacuations and power-grid protections rather than respond after the fact — a lesson from past cyclone seasons that has yet to be fully institutionalised.
