Chennai, November 14, 2023 - The Indian Meteorological Department issued a statement on Tuesday, confirming the formation of a low-pressure area over the southeast Bay of Bengal and Andaman & Nicobar Islands. Predicted to intensify into a depression and deep depression off the Andhra Pradesh coast by November 16, the system has already brought substantial rainfall.
Rainfall Records and Impact:
Velankanni in Nagapattinam district reported the highest rainfall for the second consecutive day, recording 17 cm. In Chennai, Nungambakkam and Meenambakkam weather stations documented around 5 cm of rainfall until 8 PM on Tuesday. Coastal and interior districts are expected to experience heavy rainfall over the next two days, with Chennai and its suburbs anticipating moderate to heavy showers, according to Deputy Director General S. Balachandran.
School Closures and Emergency Measures:
In response to the weather forecast, schools in several districts, including Ariyalur, Thanjavur, Villupuram, Tiruvannamalai, Nagapattinam, Tiruvarur, and Cuddalore, were closed on Tuesday. Chief Minister MK Stalin conducted an inspection at the State Emergency Operations Centre, emphasizing the need for disaster preparedness. He virtually communicated with district collectors, urging precautionary measures and ensuring the availability of essential facilities at relief centers.
Outlook and Preparedness:
Weather blogger K Srikanth highlighted the likelihood of reduced rainfall activity from November 16-17 as the deep depression recedes. However, models indicate the potential formation of another low-pressure area, possibly bringing more rains next week. As precautionary measures, ministers were dispatched to oversee districts with heavy rain forecasts, and senior IAS officers were assigned monitoring roles to coordinate rescue and relief efforts.
