Four killed in Tamil Nadu rains, more downpour expected as cyclonic circulation persists

Chennai, Nov 08: Extremely heavy rainfall is likely over some parts of Tamil Nadu and Andhra Pradesh on November 10 and 11 which may inundate roads and low-lying areas, and cause riverine flooding in some catchment areas, the India Meteorological Department said on Monday.

Surplus rain water gushed out of reservoirs while several roads here resembled swollen rivers and four persons were killed in rain related incidents in Tamil Nadu and over 60 houses suffered damage, authorities here said on Monday, as alert was sounded to people living in low-lying areas in parts of the State.

The weather department also issued a red alert for Chennai. The city has received the heaviest rainfall since the 2015 floods.

The Poondi, Cholavaram, Puzhal, Chembarmbakkam and Thervai Kandigai reservoirs here and Veeranam lake, about 230 kilometres from here released surplus water, which was cumulatively a little over 10,000 cusecs of water, as showers continued in catchment areas.

The Mettur reservoir in Salem district is expected to touch its full level of 120 feet soon and the discharge of surplus water is expected on Tuesday. People have been alerted and local authorities advised to move residents of low lying areas to safer locations.

With the catchment areas of Cauvery river in Tamil Nadu and Karnataka receiving heavy rains, the inflow of water to the dam was over 27,000 cusecs, almost touching 118 feet, official sources said. Coimbatore district administration also sounded an alert to people living in along banks of the Noyyal river in view of continuing rains. Vellore district authorities said the discharge from Ponnai Anaicut was increased to about 6,364 cusecs by evening.

In view of release of surplus water from reservoirs, an alert was sounded to people in their respective regions. In Chennai, most roads and bylanes were covered under sheets of water while there was water upto two feet in low lying localities.Power supply has also been disconnected for several neighbourhoods considering safety. A flooded city police station, Adambakkam had to be shifted to a temporary building. At least 75 trees got uprooted here and these were cleared by civic personnel.

Monsoon rains picked pace for a while and receded for some time, playing hide and seek through the day, here and in several other regions including the northern districts.

A section of subways here and in suburbs continued to be closed and traffic diversions too were on, giving road-users a harrowing time even as civic workers slogged to remove silt and de-clog drains. Southern Railway said due to rains and water-logging, 'Sunday pattern' (minimal services) would be in force on November 9 in Chennai suburban train services in Central-Arakkonam, Central-Sullurpeta (Andhra Pradesh), Beach-Chengelpet and Beach-Velachery sections.

Of the 290 water-logged areas, flood water was drained using heavy equipment in 59 localities and swift action is on to pump out flood water in the remaining 231 neighbourhoods, the government said in an official release. Four persons lost their lives in rain related incidents in Chennai, Theni and Madurai districts 'in the past 24 hours and 16 heads of cattle died, the release added.

Of the 16 city subways that witnessed flooding, water has been drained in 14 of them and the remaining two would also be free of rainwater soon, the authorities said.

As many as 237 huts were partially damaged and 26 completely and 65 and 5 houses were partially and fully damaged respectively. The government said 37 districts received rainfall and the state average was 14.2 millimetres (1.42 CM) for the past 24-hours. Since the start of northeast monsoon last month and till date Tamil Nadu has recorded about 43 per cent rainfall above normal.

While the normal is 241.2 MM (24.12 CM), the state recorded 346.1 MM (34.61 CM). In Chennai, as of now 1,107 people have been sheltered in 48 relief camps and in total 3,58,500 food packets have been provided. Similarly, in northern districts of Kancheepuram, Tiruvannamalai, Chengelpet and Tiruvallur 314 people have been housed in 10 shelters and they are being provided food and all other basic amenities. The Meteorological department advised 'alert' and preparedness on Tuesday for Nilgiris, Coimbatore, Dindigul, Theni, Tenkasi and Tirunelveli districts.

In a bulletin, the department said the cyclonic circulation over south east Bay of Bengal and adjoining South Andaman sea, extending up to 5.8 kilometres above the mean sea level, persists. Under its influence, a low pressure area is very likely to form over southeast Bay of Bengal and neighbourhood during the next 24 hours. It is likely to move west-northwestwards, concentrate into a depression and reach near north Tamil Nadu coast by November 11, early morning and bring widespread rainfall in several regions of the state, the bulletin said.

Fishermen were advised to not venture into sea for fishing between November 9 and 12. Revenue and Disaster Management Minister KKSSR Ramachandran said two teams of NDRF personnel have been deployed in Madurai and one team each in Chengelpet and Tiruvallur. Similarly, the state disaster response teams are stationed in Thanjavur and Cuddalore districts. The Tamil Nadu Fire and Rescue Services wing is on alert mode with all the necessary equipment, he said.

The 24 x 7 state control room here and those in districts could be contacted through the toll free numbers 1070 and 1077 respectively, the Minister said. People may also get in touch with authorities of Greater Chennai Corporation by using the 1913 toll free number.

The rainfall (from 8.30 AM, 7 Nov to 8.30 AM, 8 Nov) recorded here and suburban areas ranged between 4 CM and 14 CM. Other regions, including Tiruvannamalai, Kancheepuram and Cuddalore, recorded between 3 CM and 1 CM showers. For the second consecutive day, Chief Minister M K Stalin inspected affected areas and gave away flood relief assistance to affected people at Royapuram here.

To clear water-logging, inundation of subways and rain related tasks, Greater Chennai Corporation deployed 23,000 personnel who slogged amid showers to restore normalcy. Stalin has appointed 15 IAS officials to monitor relief work in 15 corporation zones.

As many as 200 special monsoon medical camps were held, in which 3,776 people received medical assistance. A total of 152 fever cases, 165 cases related to skin infections and over 2,600 other cases were treated, the corporation said. Electricity Minister V Senthil Balaji said of about 44,50,000 power connections in the Chennai distribution circle, only 12,297 connections were disconnected, considering safety. "Power supply will be restored expeditiously with receding of flood waters and rains," the Minister tweeted.

Though state-run bus services here and in other neighbouring regions continued to ply, there was disruption in services on several routes. Metrorail services were not affected.

In view of rains, prices of vegetables shot up sharply with a kilo of tomato, which was available for about Rs 30-40, a couple of days ago now being sold at Rs 90-Rs 100.

Similarly prices of other veggies also saw an increase. Considering the showers, the Arignar Anna Zoo here said a 'monsoon monitoring team' has been constituted to ensure the safety and security of animals and to undertake immediate remedial measures, if and when warranted.

Prime Minister Narendra Modi spoke to Tamil Nadu Chief Minister MK Stalin regarding the situation in the state and assured him of the Centre's support in rescue and relief work. While four National Disaster Response Force (NDRF) teams have been deployed in Madurai, Chengalpet and Tiruvallur for rescue work, State Disaster Response Force teams have been sent to Thanjavur and Cuddalore districts.

A cyclonic circulation lies over the southeast Bay of Bengal and the adjoining south Andaman Sea extending up to middle tropospheric levels. Under its influence, a low pressure area is very likely to form over the southeast Bay of Bengal and neighbourhood during the next 24 hours. It is likely to move west-northwestwards, concentrate into a depression and reach near north Tamil Nadu coast by the early morning of November 11, the MeT office said.

"Under its influence, isolated heavy to very heavy rainfall is likely over Tamil Nadu on November 8 and 9 and heavy to very heavy rain at few places with isolated extremely heavy falls are very likely on November 10 and 11. Heavy to very heavy rain with extremely heavy falls at isolated places are also likely over south coastal Andhra Pradesh during the same period," the IMD said in a statement.

Rainfall recorded between 64.5 mm and 115.5 mm is heavy and between 115.6 and 204.4 is very heavy. Anything above 204.4 mm is considered extremely heavy rainfall.

Squally weather with winds gusting up to 60 kmph is predicted over southwest and adjoining west-central Bay of Bengal and along and off south Andhra Pradesh-Tamil Nadu coasts and Gulf of Mannar for the next four days.

Similar conditions are likely over Southeast Bay of Bengal during the next two days. Fishermen are advised not to venture into these areas, the IMD said. It also warned of localised flooding of roads, inundation and water logging in low-lying areas and closure of underpasses mainly in urban areas.

There is a possibility of localised landslides, minor damage to 'kutcha' roads, vulnerable structures and to horticulture and standing crops in some areas. It may also lead to riverine flooding in some river catchments, the IMD said.

The weather office said a depression over east central Arabian Sea has moved west-northwestwards in the last six hours with a speed of 8 kmph and lay centred over East-central Arabian Sea about 840 km west-southwest of Mumbai and 800 km west-southwest of Panjim. It is likely to move nearly westwards and weaken into a well-marked low-pressure area by Tuesday morning. Thereafter it is likely to move west-southwestwards. Fishermen are advised not to venture into these areas, it said.
