Chennai, Oct 21(NationPress) A new low-pressure system has formed over the Bay of Bengal, leading the Regional Meteorological Centre (RMC), Chennai, to predict substantial rainfall across Tamil Nadu in the upcoming days. This weather pattern is a precursor to the northeast monsoon, and areas including Chennai and its surrounding suburbs have already begun to experience extensive showers.
The ongoing rains have caused a considerable rise in the water levels of significant reservoirs and lakes, prompting authorities to take precautionary actions.
One of the main sources of drinking water for Chennai, the Chembarambakkam Lake, has observed a continuous increase in inflow over the last 48 hours.
Officials have reported that the lake's water level is nearing 21 feet, just three feet shy of its maximum capacity of 24 feet.
With the rising inflow from upstream catchment areas, discussions among district and water resource officials have centered on the necessity for controlled water release.
After a review meeting on Tuesday, authorities resolved to begin releasing excess water from Chembarambakkam Lake starting at 4 p.m.
The initial discharge rate will be set at 100 cubic feet per second (cusecs) as a precaution, with officials closely observing inflow patterns and weather forecasts to evaluate the need for additional releases.
The Water Resources Department and Revenue officials have issued flood warnings to residents along the banks of the Adyar River and in low-lying areas near Kundrathur and Thirumudivakkam. Local administrations have been placed on high alert, with field teams ready to manage any potential flooding scenarios.
The RMC has cautioned that heavy to very heavy rainfall is anticipated in northern coastal districts, including Chennai, Tiruvallur, Chengalpattu, and Kancheepuram, in the next 48 hours.
Fishermen have been warned against entering the southwest and adjacent west-central Bay of Bengal due to hazardous sea conditions. As the northeast monsoon is expected to strengthen, officials have emphasized the importance of ongoing monitoring of water bodies and timely discharge of surplus water to avert flooding in Chennai and neighboring regions.
