August 7: The activity will continue, though the intensity may gradually decrease by the evening.
The IMD has advised people to take precautions during thunderstorm hours, avoid open areas, and ensure safety during lightning occurrences.
Synoptic Features
According to the IMD’s synoptic analysis, the monsoon trough at mean sea level currently extends from Amritsar, Chandigarh, Shamli, Shahjahanpur, Lucknow, Chapra, Bankura, Canning and moves southeastward into the northeast Bay of Bengal.
An upper-air cyclonic circulation has developed over northwest Bihar and adjoining northeast Uttar Pradesh, extending up to 4.5 Km above mean sea level.
This system is tilting southwestwards with height, which enhances moisture incursion and instability over Jharkhand.
These weather systems are collectively responsible for localized thunderstorms and strong winds across eastern India, including Jharkhand.
