KOLKATA: The city could be lashed by spells of heavy shower on Saptami under the impact of a deep depression that will hit the Bengal-Bangladesh coast on October 23 afternoon, moving along the same route that had been taken by cyclone Amphan. The rain could be accompanied by winds at a speed of 30km/hr-40km/hr with occasional gusts of up to 50km/hr, said the Met office. Along with Kolkata, Howrah, Hooghly and Nadia could receive light to moderate showers while East Midnapore, North and South 24 Parganas are likely to receive heavy rain on Friday.
A bulletin issued by the Regional Meteorological Centre (RMC), Alipore, said that Wednesday’s “well-marked low pressure area over west-central Bay of Bengal has concentrated into a depression over northwest and adjoining west-central Bay of Bengal and lay centred about 180km south-southeast of Paradip (Odisha), 350km south-southeast of Sagar Islands and 490km south-southwest of Khepupara (Bangladesh)”. It is set to intensify further into a deep depression in next 24 hours and move north-northeastwards and cross Bengal and adjoining Bangladesh coasts as a deep depression between Sagar islands and Khepupara by October 23 afternoon. This is the same region that was hit by cyclone Amphan on May 20 and wreaked havoc across south Bengal, including Kolkata.
But the impact of Friday’s deep depression is likely to be a much lesser one, said weathermen. “Even though it will hit the same coastal areas, the system will steadily lose strength as it moves over land in a northeast direction towards Bangladesh. Depending on the time of its landfall — which is likely to be Friday afternoon — it could be nearest to Kolkata early in the evening. We expect the showers in the city to intensify around that time and then gradually taper off. But the rain will continue till the first half of Saturday,” said RMC director G K Das.
One or two places in Kolkata, Howrah, Nadia and Hoogly could receive 70mm-110mm rain on Friday, it has been predicted. This could lead to waterlogging in some parts of the Kolkata Municipal Corporation area, warned the RMC. KMC has already alerted the executive engineers of all major drainage pumping stations to get ready for a heavy downpour. Leaves of KMC sewerage & drainage department offi-cials and workers have been cancelled.
“We are keeping a vigil over functioning of our drainage pumping stations. We need to keep all heavy-duty pumps functional to flush out storm water in case of heavy rain. We will be keeping focus on low-laying areas where there is no underground drainage system. We will be pressing into service portable pumps to flush out storm water from these areas,” said a KMC drainage department official.
