‘Amphan’ is likely to make a landfall somewhere between Digha and Hatiya islands in Bangladesh close to the Sunderbans, a UNESCO World Heritage Site, between afternoon and evening of Wednesday, India Meteorological Department (IMD) said. The intensity near the centre of the storm was 170 kmph to 180 kmph gusting to 200 kmph, the weatherman said, adding gale-force winds of 110-120 kmph will slam Kolkata when the cyclone passes over it later in the day, before weakening further into a cyclonic storm over Nadia and Murshidabad in West Bengal.
