New Delhi: Heavy rains on Sunday (November 7, 2021) continued to lash Chennai and its suburban areas with authorities sounding a preliminary flood alert to people as two city reservoirs are set to be opened.
The authorities have informed that the Chembarambakkam and Puzhal reservoirs, which serve as important sources of drinking water to Chennai city, would be opened to let out surplus rainwater that has resulted in waterlogging all around.
Sounding a preliminary flood alert, the state water resources authorities advised district collectors of Kancheepuram and Tiruvallur to evacuate people living in low-lying areas and house them in safe locations.
The Chennai and several suburbs in Kancheepuram and Tiruvallur districts have been witnessing intermittent rains and showers since Saturday morning.

Earlier on Saturday afternoon, the India Meteorological Department (IMD) had predicted heavy rainfall at isolated places over Tamil Nadu for the next five days.
“A cyclonic circulation lies over Southeast Bay of Bengal and adjoining the equatorial Indian Ocean off Sumatra Coast. Under its influence, a low-pressure area is likely to form over Southeast Bay of Bengal around November 9. It is likely to become more marked and move west northwestwards towards north Tami Nadu coast during the subsequent 48 hours,” the Met department had said in a weather bulletin at 1 PM on Saturday.
Increase in rainfall activity with heavy to very heavy rainfall at a few places and extremely heavy rain at isolated places likely over north coastal Tamilnadu and heavy to very heavy rainfall at a few places over south coastal Andhra Pradesh during 11th-12th November, 2021.
