A motorcyclist wades through the flooded waters at Ritherdon Road, Vepery, Chennai on Friday. Heavy rains lashed Chennai throwing normal life into tizzy for the past three days.

Rains continued to lash Chennai and neighbouring districts of Kancheepuram, Tiruvallur besides other regions of Tamil Nadu, even as the MeT department forecast more rainfall due to a low pressure area persisting in the Bay of Bengal.

The fury continued in Chennai and other coastal regions of Tamil Nadu, with the metropolis gauging 93% more showers than normal for the October one to November 4 period.

The MeT department said low pressure area and upper cyclonic circulation in the Bay of Bengal are likely to bring more rains.

Light to moderate rains were recorded in some areas in the state.

Eight persons have died so far since the onset of the northeast monsoon in the state on October 27.

For the October 1 to November 4 period, 19 cm of rainfall was recorded in Tamil Nadu against the normal of 21 cm, Director, Area Cyclone Warning Centre, S. Balachandran said.

Chennai gauged 62 cm of precipitation against the normal of 32 cm for the period, he said.

Chennai received 6 cm of rains in Meenambakkam and 7 cm in Nungambakkam, Nagapattinam 9 cm and Ponneri 10 cm, according to MeT department data.


Commuters had a harrowing time due to delayed services of buses and trains and severe traffic snarls. Mild rainfall was recorded in some areas in the state, moderate in others and heavy in some pockets.

Schools and colleges, closed since October 31, were shut on Saturday as well and several university exams were postponed. The state-level National Talent Search Exam scheduled for Saturday was deferred to November 18.

Civic authorities, including corporation officials, district collectors (Kancheepuram, Tiruvallur) coordinated relief work.

Power supply

Power supply was suspended in inundated areas such as parts of MKB Nagar in North Chennai, pockets of Madipakkam in South Chennai and Karapakkam off Porur in Western Chennai to ensure safety.

Netizens posted updates about traffic diversions and inundated areas on social media and volunteers distributed food packets and water in affected areas of Nanmangalam and Pallikaranai here.

Chief Minister K. Palaniswami had on Friday visited many waterlogged parts of the city and its suburbs, insisting that his government was working on a “war-footing”. He was accompanied by his deputy O Panneerslevam and senior officials.

Low pressure in Bay of Bengal

Meanwhile, a MeT bulletin said the low pressure area over south west Bay of Bengal, adjoining Sri Lanka and Tamil Nadu coast and the associated cyclonic circulation extending up to 3.1 km above mean sea level continued to persist.

With the north east monsoon active in the state and neighbouring Puducherry, Chennai city (Nungambakkam) recorded 65.8 mm of rainfall while suburban Meenambakkam registered 62 mm rains in 24 hours ending 8.30 a.m. on Saturday.

The coastal district of Nagapattinam in the Cauvery delta zone recorded 2 cm rain and Karaikal in Puducherry one cm rain from 8.30 a.m. to 5.30 p.m. on Friday. Comprehensive updates on rainfall for other regions till Saturday morning are awaited.

The MeTt department said rain or thundershowers were likely to occur at many places over coastal Tamil Nadu and Puducherry and at a few places over interior Tamil Nadu.

Heavy rain at isolated places was very likely over Tamil Nadu and Puducherry, it said.

Suburban railway services

A release from the railways said showers caused track “circuit based signalling to fail” due to water logging in Chennai Division, “affecting punctuality” between Kodambakkam-St Thomas Mount stations in the southern sector from 9 p.m. on Friday and it was restored at 9.50 p.m.

This was also the case at the northern Tondiarpet and Korukkupet route at 9.35 p.m. and services were restored at 5.45 a.m. on Saturday, the release said.

“Wherever automatic signalling got affected, trains got slightly delayed since they had to be dealt with manual signals instead of automatic signals,” it said.

There were also some power tripping issues in railway routes, including the northern suburban Chennai Beach-Central-Tiruvallur. Power was immediately restored by extending supply from adjacent sub stations within a few minutes, they said.

On Saturday morning, a rail fracture was detected between St. Thomas Mount and Pallavaram stations and it was attended and set right soon after, they said.

“Except for some minor delays, train services including Chennai Suburban Services are being maintained normally and monitored continuously by railway officials,” they said.
