2 cyclones are churning in Arabian sea

As severe cyclonic storm ‘Maha’ has moved further over east-central Arabian sea and Lakshadweep area, rainfall over Tamil Nadu may begin to ease from Friday afternoon.

Meanwhile, two city reservoirs — Red Hills and Poondi Red Hills lake, which are major drinking water sources — received copious inflow from various catchment areas, such as Vellanurkandigai, Pammadukulam and Arikambedu. On Thursday, a stretch of Pothur-Red Hills Road was flooded with rainwater flowing into Red Hills lake.

Officials of the Water Resources Department said besides surplus water from lakes such as Vellanur Periaeri and Pothur, Red Hills reservoir receives floodwater runoff from areas such as Morai, Pothur, Pakkam, Kovilpadagai and Tirumullaivoyal. Overnight rains have translated into a heavy inflow of 1,059 cusecs into Red Hills lake. Of this, nearly 380 cusecs was transferred from Poondi lake for water supply. P.Vijaya, a resident of Konimedu, said the new bridge adjacent to the road has made travelling on the stretch better.

The Poondi reservoir is nearly 50% full, as it now has 1,648 mcft against its capacity of 3,231 mcft. It is receiving an inflow of 1,320 cusecs, which includes Krishna water. However, storage in Cholavaram and Chembarambakkam reservoirs remains low. In a single day, the combined storage of the four reservoirs has gone up by about 200 mcft, which is equal to nearly a week’s water supply.

The Meteorological Department has forecast that many places may get moderate rainfall and one or two places in districts, including Kanniyakumari, Tirunelveli, Coimbatore, Krishnagiri and Salem may receive heavy to very heavy rainfall till Friday morning.

From Friday noon, rainfall activity would reduce and up to 50% of the weather stations over the State may receive showers. Chennai too would record only light to moderate showers in some areas till Saturday.

Another low pressure

However, there are prospects for another low pressure area over the north Andaman sea on November 3. It is likely to intensify into a depression over east-central Bay of Bengal in the next two days. S.Balachandran, Deputy Director General of Meteorology, Chennai, said.

“We are monitoring the prospects of the weather disturbance. We have to wait for the movement of the system to determine its extent of impact over Tamil Nadu.”

It is the first time in the past 58 years that two cyclones are churning in Arabian sea. “We have had two cyclones following one after another in 2015 and 2018 in Arabian sea. But two cyclones, ‘Maha’ and ‘Kyarr’ are prevailing simultaneously for the first time since 1961.”

In October 2015, the extremely severe cyclonic storm ‘Chapala’ was followed by another extremely severe cyclonic storm ‘Megh’.

In May 2018, cyclone ‘Sagar’ was followed by cyclone ‘Mekunu’, he recalled.
