Chennai, Nov 22 (NationPress) The Regional Meteorological Centre (RMC) in Chennai has predicted significant rainfall in 11 districts of Tamil Nadu this Saturday, as a new weather system develops over the Bay of Bengal. According to the most recent bulletin, an atmospheric circulation over the southern Andaman Sea has set the stage for the emergence of a low-pressure area in the southeast Bay of Bengal later today.
This system is anticipated to progress in a west-northwest direction and is likely to evolve into a well-defined low-pressure area within the next 48 hours.
Further strengthening is also expected as it continues its path towards the Indian coastline. In light of this evolving situation, the RMC has forecast widespread rainfall across the southern and delta regions.
Heavy downpours are predicted in Kanyakumari, Tirunelveli, Thoothukudi, Tenkasi, Ramanathapuram, Pudukottai, Thanjavur, Tiruvarur, Nagapattinam, Mayiladuthurai, and Cuddalore districts.
The nearby Karaikal region of Puducherry is also predicted to experience heavy showers. The weather office has indicated that Chennai and surrounding areas will have partly cloudy skies throughout the day.
Some areas of the city may experience moderate showers along with thunder and lightning during the evening or nighttime hours.
Officials noted that the influence of the atmospheric circulation and the developing low-pressure area could increase rainfall intensity in both coastal and interior regions of southern Tamil Nadu.
Fishermen are strongly advised against venturing into the southeast and southwest Bay of Bengal, including the adjacent Andaman Sea, where turbulent sea conditions and brisk winds are predicted for the next two days.
The Meteorological Department has warned that the sea may remain turbulent due to the anticipated strong winds generated by the intensifying system. Fishermen already at sea are urged to return to shore promptly. With numerous districts expecting heavy rainfall, authorities have instructed local administrations to stay vigilant, monitor water levels in low-lying and flood-prone areas, and prepare for any contingencies related to flooding or traffic disruptions.
As the weather system intensifies, Tamil Nadu is likely to witness increased rainfall activity over the weekend, with meteorologists closely tracking its movement and intensity.
