Areas like Koyambedu, Anna Nagar, Choolaimedu, Nungambakkam in the city and suburbs like Poonamallee, Maduravoyal, Alandur, Madipakkam and Meenambakkam have been recording steady spells since 7am.
IMD said Nungambakkam and Meenambakkan weather stations recorded 3mm rainfall till 5.30am. But strong steady spells started only after 7am.
The weather agency has forecast thunderstorms with light to moderate rain at isolated places over Coimbatore, Tiruppur, Chennai, Kancheepuram, Tiruvallur, Chengalpattu, Vellore, Ranipet, Tirupattur, Tiruvannamalai and Villupuram districts of Tamil Nadu and Puducherry for the next one to three hours.
The strong wind and heavy rain affected trains. Suburban trains on Tiruvallur route were disrupted for an hour after an overhead power cable developed a snag at around 7.30am. This delayed suburban trains on the route. A few of the incoming express trains from the south and western lines were also delayed as there was strong wind near Chengalpet at night and near Tiruvallur in the morning. At Chengalpet railway station, a platform stall toppled and slammed into a parked suburban train and a few roof tiles were damaged in the wind after midnight.”
A Elumalai, public relations officer of Chennai division of Southern Railway said, “suburban trains were delayed for an hour after an object swept by the wind got entangled on the overhead power cable. It has been set right and services have resumed.”
The Indian Coast Guard said ICGS Shaurya and ICGS Sagar with helo embarked onboard have been deployed for responding to any contingency, including rescue operations post landfall of Cyclone Asani. Safety advisory have been issued by the Coast Guard to ships and oil handing agencies to initiate preventive measures.
