What will the weather be like across South Bengal?
The latest IMD warning bulletin shows no warning for Gangetic West Bengal from October 2 through October 8. However, recent observations show that rain has occurred in several southern locations, including Dum Dum, Salt Lake, Sunderban, Howrah, Alipore and Krishnanagar. Therefore, residents may continue to see localised changes in weather, with rain occurring in some pockets while nearby areas remain comparatively dry.
What should residents expect over the coming days?
Overall, West Bengal is likely to experience mixed weather conditions, with the possibility of thunderstorms and lightning mainly over the northern part of the state on October 2 and 3. After that, the IMD has not listed any specific warning through October 8. The recent rainfall pattern also suggests that showers can remain highly localised, so conditions may vary considerably between neighbouring districts and cities.
