The Bangladesh Meteorological Department (BMD) has issued a weather bulletin predicting storms across three specific regions of the country. According to the forecast released on Tuesday, May 12, 2026, wind speeds may reach up to 60 kilometres per hour (km/h) by the evening. Consequently, river ports in the affected areas have been advised to hoist cautionary signals to ensure the safety of maritime activities.
Meteorological Forecast and Warnings
The weather office provided an internal river port forecast valid from 9:00 am to 6:00 pm on Tuesday. The report indicates that the regions of Rangpur, Tangail, and Mymensingh are likely to experience temporary gusty or squally winds originating from the West or North-West.
The wind velocity is expected to fluctuate between 45 km/h and 60 km/h, accompanied by rain or thundershowers. Due to the potential for turbulent weather conditions, river ports within these three jurisdictions have been instructed to display Cautionary Signal Number 1. This signal is a standard advisory for river ports, indicating that a region is threatened by squally weather of temporary nature.

Regional Safety and Local Incidents
The directive for Cautionary Signal Number 1 serves as a notification for small vessels and commuters using riverine routes to remain vigilant. The BMD’s monitoring of North-Western wind patterns often coincides with seasonal atmospheric instability, which can lead to sudden escalations in wind intensity near major river basins.
In a separate development reported from the Gaibandha district, local authorities have confirmed the deaths of three individuals following canine attacks. The incidents involving dog bites have resulted in widespread concern and panic throughout the local community. Public health officials are reportedly monitoring the situation to prevent further occurrences and to address safety concerns regarding stray animals in the region.
The Meteorological Department continues to monitor the prevailing atmospheric conditions. While the current warning is specific to the evening of Tuesday, residents and maritime operators in the northern and central belts of Bangladesh are advised to follow official updates regularly. The involvement of thunder and lightning during these squalls necessitates additional precautions, such as seeking sturdy shelter during the peak hours of the forecasted storm.
