An orange alert has been issued for Tiruvallur district for 24 hours ending 8.30 a.m. on Wednesday (October 29). Eight more districts, including Kancheepuram and Ranipet, are likely to receive heavy rainfall until the severe cyclonic storm makes landfall.
During the past 24 hours ending 8.30 a.m. on Tuesday, several places in extreme north Tamil Nadu received intense downpour. Ennore in Chennai recorded the heaviest rainfall of 13 cm, followed by Virinjipuram in Vellore (11 cm). While Chennai and its neighbouring districts recorded widespread, moderate to heavy rainfall, other districts like the Nilgiris, Coimbatore, Villupuram, and Thoothukudi also received light rainfall.
RMC forecast
Tamil Nadu’s north coastal and adjoining districts may experience strong surface winds with speeds reaching up to 55 kmph under the influence of Cyclone Montha, according to the RMC.
With another depression remaining practically stationary over Arabian Sea, districts like Theni, Tenkasi, Kanniyakumari, and the Ghat areas of Coimbatore may receive heavy rains till Wednesday morning.
On Tuesday, Chennai is likely to experience moderate to heavy rainfall in some areas and a pleasant, winter-like weather, as the maximum temperature is likely to hover around 25 degree Celsius. Rainfall over Tamil Nadu may reduce gradually from Wednesday, once the cyclone makes its landfall.
Water levels rise
Meanwhile, the city reservoirs, including Red Hills and Chembarambakkam, received light rainfall of 1-2 cm between 8.30 a.m. and noon. The Water Resources Department (WRD) will open the floodgates of the Red Hills reservoir wider to discharge 1,000 cusecs of water around 2 p.m. on Tuesday to manage the rise in the inflow.
Officials of the WRD noted that the minor irrigation tanks located upstream of the reservoir are nearly 95% full and the reservoir received an inflow of 556 cusecs. Water discharge is also being maintained in other two key reservoirs: Poondi and Chembarambakkam.
On Tuesday, Chennai’s six drinking water sources, including Veeranam tank in Cuddalore district, had a total storage of 10.18 thousand million cubic feet against their capacity of 13.22 tmcft. The waterbodies had a combined storage of 6.14 tmcft on the same day last year.
A total of 711 sewer cleaning vehicles, including those hired from other districts, are in operation to clear sewer blocks, according to Chennai Metrowater.
