The Bangladesh Meteorological Department (BMD) has issued a weather advisory warning of impending squally winds and thundershowers across twelve inland districts. According to the forecast, temporary gusty or squally winds ranging between 45 and 60 kilometres per hour, accompanied by rain or thundershowers, are expected to pass over these regions.
Affected Areas and Maritime Alerts
The weather bulletin, issued on Wednesday evening and remaining valid through Thursday morning, identifies several vulnerable riverine zones across northern, central, and south-eastern Bangladesh. The districts falling under the advisory include Rangpur, Dinajpur, Rajshahi, Pabna, Bogra, Tangail, Mymensingh, Comilla, Noakhali, Chittagong, Cox’s Bazar, and Sylhet.
Surface winds across these regions are expected to blow primarily from the south or south-east. Owing to the potential for sudden gusts and choppy water conditions along major river systems, maritime authorities have instructed all inland river ports within the designated districts to hoist Distant Cautionary Signal Number 1. Launch operators and small vessel captains navigating these waterways have been advised to exercise heightened caution.
Seasonal Monsoon Context
August falls squarely within Bangladesh’s active monsoon season, a period marked by heavy moisture inflow from the Bay of Bengal and frequent atmospheric instability. Strong surface winds combined with localized downpours often generate sudden turbulence over river channels, creating hazardous conditions for passenger launches, fishing trawlers, and cargo barges reliant on the country’s inland network.
While monsoon precipitation provides vital irrigation for active agricultural production—particularly for the Aman paddy crop across northern districts such as Rangpur, Dinajpur, and Bogra—intense spells of rain can cause brief waterlogging in low-lying urban areas. Port officials and local administrative bodies across the twelve districts continue to track weather patterns closely to ensure waterway safety as the system moves through.
