Over the past three days, Sirajganj’s Tarash logged 120mm of rainfall, while Tetulia in Panchagarh received 162mm — both considered “very heavy rain”, defined as precipitation exceeding 88mm in a day. Farmers in flood-prone regions often keep Aman rice for household consumption as protection against future calamities. Yet even amid devastation, some scientists see a possible silver lining: heavy rain could temporarily curb the dengue outbreak that has surged this year.
