The Bangladesh Meteorological Department (BMD) has issued alerts for gusty winds and thundery showers in parts of the country, linked to a low-pressure system forming over the Bay of Bengal. The department reported that a trough of low pressure currently extends over West Bengal and adjacent regions, while the seasonal normal low-pressure area remains positioned over the southern Bay of Bengal.
Short-Term Outlook
From Sunday, 22 March, 6:00 p.m., for the next 24 hours, isolated locations in Mymensingh, Chattogram, and Sylhet divisions may experience gusty winds accompanied by thundery rainfall and occasional lightning. The remainder of the country is expected to see partly cloudy skies with generally dry conditions. Daytime temperatures may rise slightly by 1–2°C, with night temperatures seeing a marginal increase.
