Kolkata: The city was lashed by a thunderstorm which is the third one of this month. It triggered a steady drizzle, uprooted trees and disrupted traffic in some parts of Kolkata.
A cyclonic circulation that stretched between Bihar and north Bengal also aided the storm. According to the Met office, it was triggered by clouds that were generated in the neighbouring districts of Hoogly, Burdwan and Nadia.
Mercury dropped by as much as six degrees, tumbling to around 24°C from 30°C. The cooling effect lasted through the day. Real feel temperature — calculated based on humidity, intensity of sun rays, wind speed, cloudiness and precipitation — dropped below 30°C, according to a private weather forecasting service. It slid to 21°C early in the evening.
The Met office didn’t rule out the possibility of a thunderstorm on Thursday. Conditions remain favourable due to the incursion of moisture and the presence of the circulation.
