Following a brief lull, Tamil Nadu is gearing up for a resurgence of fairly widespread rain, courtesy of a low-pressure area expected to form by Tuesday. The weather system is poised to bring substantial rainfall to coastal districts and adjacent areas until November 15, potentially alleviating the significant deficit in seasonal rainfall.
The Regional Meteorological Centre predicts heavy to very heavy rainfall (up to 20.4 cm) in isolated locations, including Chengalpattu, Kancheepuram, Cuddalore, and Villupuram districts on Tuesday. Chennai is expected to experience moderate to heavy rain on the same day. The impact of this weather system is likely to extend to 15 districts in north and interior Tamil Nadu, encompassing Chennai, Vellore, Ariyalur, and Delta districts. Intense rainfall, reaching up to 11.5 cm, is forecasted for certain places in Chennai and neighboring districts, persisting into Wednesday.
S. Balachandran, Additional Director General of Meteorology, highlighted the influence of two weather systems, with one potentially developing into a depression over the Bay of Bengal. Despite light rain in some areas on Monday, Tamil Nadu remains at a seasonal rainfall deficit of 17%, emphasizing the significance of the anticipated rainfall.
