A week before the recent devastating landslides in the Chattogram region, the BMD forecast consecutive days of heavy to very heavy rainfall and explicitly warned of landslide risks. Rainfall between 115 and 204 mm is classified as very heavy, while rainfall of 205 mm or more is categorised as extremely heavy. One proposal under consideration would raise the lower limit for very heavy rainfall from 89 mm to 150 mm, requiring a broader recalibration of the entire rainfall classification system. We warned about very heavy rainfall and also about landslides.” Regarding the current definitions of heavy and very heavy rainfall, Momenul said the department is considering revising the rainfall thresholds.
