On Thursday Morning A steady drizzle interspersed by a couple of heavy spells left Kolkata drenched even as the Met office predicted more showers on Friday. rain could be sporadic and less intense over the next 48 hours. Kolkata received 15.5mm rain on Thursday.
A cyclonic circulation over Gangetic Bengal and the monsoon trough, which now passes over Digha, combined to trigger the rain on Thursday. It started with a drizzle shortly after 8am and continued till 1pm in the afternoon.
Regional Meteorological Centre (RMC) director G K Das said,” The circulation over Gangetic Bengal has moved away towards Jharkhand. So, the showers will now lose intensity and will be less frequent. But light rain will continue till the weekend. As of now, there is no possibility of heavy showers since there is no rain-triggering system in the region”.
