Various meteorologists predicted steady rainfall in West Bengal and Bangladesh this weekend.
The meteorologists, however, were scattered over their opinion on the reason of this rainfall. The regional meteorological centre – at Kolkata’s Alipore said that a depression has formed over central and adjoining South-east Bay of Bengal and lay centred at 730 km South-east of Paradip. The depression will initially move North-west during the next 24 hours and then re-curve North-east-wards, towards Bengal coast during the next 48 hours. It is likely to intensify further. Rainfall at many places over Gangetic West Bengal during the next 72 hours is expected.
But the AccuWeather Meteorologist predicted, regardless of the intensity of a budding tropical cyclone in the Bay of Bengal, flooding rain will threaten Eastern India and Bangladesh this weekend. Currently a depression, the system will parallel the coast of Eastern India into Saturday. The depression will then make rain in Bangladesh as early as this weekend. Prior to approaching Bangladesh, AccuWeather Meteorologist Courtney Spamer said the conditions are conducive for the depression to become a deep depression or even a named cyclone. “The best chance for it to strengthen into a cyclone will be into Saturday morning,” she said. However, the depression would not become stronger than Cyclone Kyant.
Meanwhile, Skymet weather Service Private Limited said, the depression over central and adjoining South-east Bay of Bengal will continue to move in the North-west direction and is likely to intensify into a deep depression soon. With this, scattered light to moderate rains are likely over coastal areas of Andhra Pradesh and Odisha on Friday. Few places may record some heavy showers as well. However, with system moving away, rains will now reduce over Tamil Nadu including Chennai. Meanwhile, Kerala will continue with light to moderate rains. This system is also likely to give scattered rain in Gangetic West Bengal including Kolkata and North-eastern states of Nagaland, Manipur, Mizoram and Tripura.
Kolkata has received 41.7 mm rainfall till 8.30 am on Friday, the MeT department said, adding cloudy conditions will prevail with one or two or two spells of rain or thundershowers in the city during the weekend. Fishermen have been advised to not to venture into sea along and off North Andhra Pradesh coast on November 4 and 5, and along and off Odisha and Bengal coast during November 4-6. Between November 4 and 6, West Bengal may witness wind at 50-60 km an hour.
