@ChennaiRains "IMD announced the onset of #NEM2025 yesterday. With an LPA expected to form over SE Arabian Sea in the next XX hours and another possible LPA next week in South Bay conditions look good for a wet couple of weeks for most of Tamil Nadu. For the next couple of days South TN Delta and parts of West TN may see more rains with action shifting to North Coastal TN early next week. Chennai and suburbs may continue to see wet weather until then with light / moderate rains daily with heavier spells during night and morning hours. Today we may see heavy rains in many places over South TN and few places"

"South TN under watch for heavy to very heavy rains. Three different convective clusters triggering thunderstorms. Parts of interior Thoothukudi district seeing moderate thunderstorms which could gradually intensity and move into Virudhunagar district. The 2nd cluster is giving rains over parts of Kanyakumari and Tirunelveli district which may bring more rains during the evening hours. The 3rd cluster currently over Palk strait is the one to watch out for. This could give widespread heavy rains over Ramanathapuram and Thoothukudi districts with few places coming under very heavy rains tonight"

"Northeast Monsoon is just days away. Last year under the instruction of the Green Tribunal the temporary structures in Cooum were cleared before NEM season. This year so far they have not been cleared. I hope they are cleared soon and free passage for water to flow through the river is made without any delay. @chennaicorp. @kgbias please look into this sir. Maybe it might come under the mandate of NHAI but any water logging / flooding due to reduced water flow will impact the function of the GCC setup. Image taken from Naduvankarai bridge Anna Nagar"
