More downpour has been forecast till tomorrow.
The Met department forecast heavy rain at isolated places in Gangetic West Bengal till 8.30 AM tomorrow, while the districts in sub-Himalayan West Bengal are likely to receive heavy downpour at isolated places from tomorrow.
Incessant drizzling with one or two spells of heavy showers marred the pre-puja activities like shopping and decorations of pandals at different parts of south Bengal.
The day being 'Mahalaya', which according to the Hindu almanac marks the end of 'Pitri Paksha' and the beginning of 'Devi Paksha', lakhs of people congregated on the banks of Hooghly river here and at other rivers and waterbodies braving continuous drizzling to pay obeisance to their ancestors.
Other places in South Bengal where significant rains occurred during the day are Kalaikunda (38 mm), Medinipur (29 mm), Mogra (27 mm) and Panagarh (22 mm), the Met department said.
