Chennai, Oct 19 (NationPress) The Regional Meteorological Centre (RMC) in Chennai has issued a weather alert predicting extensive rainfall across Tamil Nadu over the upcoming four days, triggered by a low-pressure system forming over the southeast Bay of Bengal and the adjacent South Andaman Sea.
According to the RMC, a low-pressure area is currently situated over the South Andaman Sea and nearby southeast Bay of Bengal. This system is anticipated to strengthen into a well-defined low-pressure zone by October 21, moving west-northwest and intensifying as it approaches the Tamil Nadu coastline.
Consequently, light to moderate rain, accompanied by thunder and lightning, is expected in various regions of Tamil Nadu, Puducherry, and Karaikal on Sunday.
Heavy rainfall is also anticipated in isolated areas, particularly within the hilly terrains of Coimbatore district and the districts of The Nilgiris, Erode, Tiruppur, Theni, Tenkasi, Tirunelveli, and Kanniyakumari.
The forecast for Monday (October 20) indicates heavy downpours in isolated locations within Chengalpattu, Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, Pudukottai, Ramanathapuram, Kallakurichi, and parts of Coimbatore and Erode districts.
Moderate rainfall is also expected in Madurai, Dindigul, and Virudhunagar, along with the union territories of Puducherry and Karaikal.
On October 21, heavy rain is projected in several areas of Villupuram, Chengalpattu, Cuddalore, Mayiladuthurai, Nagapattinam, and Puducherry-Karaikal.
The strengthening of the system is likely to lead to increased rainfall intensity in coastal and nearby interior districts. A red alert has been issued for October 22 for northern coastal Tamil Nadu.
Districts such as Tiruvallur, Chennai, Chengalpattu, Kancheepuram, Villupuram, and Ranipet are expected to receive heavy to very heavy rainfall, while Cuddalore, Kallakurichi, Tiruvannamalai, Tirupattur, and Vellore may also experience significant downpours.
In Chennai, the sky will likely remain mostly cloudy with light to moderate rain, possibly accompanied by thunder and lightning in certain areas.
The maximum temperature is expected to hover around 28-29 degrees Celsius, while the minimum may fall between 25-26 degrees Celsius. The Meteorological Department has advised fishermen to refrain from venturing into the sea due to anticipated rough conditions in the coming days.
