The Bangladesh Meteorological Department has issued a warning indicating the possibility of squally weather affecting the Sylhet region by 6:00 pm on Sunday, with wind speeds potentially reaching up to 60 kilometres per hour. The forecast also indicates the likelihood of rain or thunderstorms accompanying the adverse weather conditions.
According to the inland riverine weather bulletin issued by the Meteorological Office, the advisory remains valid until 6:00 pm on Sunday (19 April). The warning specifically highlights that areas within the Sylhet division may experience temporary gusty or squally winds originating from the west or north-west direction.
The bulletin, signed by meteorologist Md Abdul Hamid Mia, states that wind speeds are expected to range between 45 and 60 kilometres per hour during these periods of instability. Such conditions may occur intermittently rather than continuously, with sudden onset typical of squall activity. In addition, the forecast includes the possibility of rain or thunderstorm activity in the affected areas.
In response to the forecast, inland river ports in the Sylhet region have been advised to display Signal No. 1. This is a precautionary alert indicating that distant squalls or adverse weather conditions may affect river navigation, requiring vessels to exercise caution while operating in the region.
Signal No. 1 is generally used by authorities to indicate the presence of potentially unstable weather conditions that could impact river transport. It does not necessarily indicate severe danger but serves as an early warning to ensure safety precautions are taken by operators of boats and other water vessels.
