A kalbaisakhi, also known as a nor'wester or bordoisila in Assam, is a localised rainfall and thunderstorm phenomenon occurring in Bangladesh and Indian states like Bihar, Jharkhand, Odisha, Tripura, Assam and West Bengal. These events take place during the summer and pre-monsoon season. Typically happening in the afternoon or just before sunset, kalbaisakhi is characterised by the sudden appearance of thick, dark clouds leading to gale-speed winds, torrential rain, thunderstorms and sometimes hail, but they are brief.
