Bangladesh's Heavy Rainfall Examined With IMERG
At least 156 people in Bangladesh were killed during the past week by landslides and floods caused by heavy rainfall. Monsoon rainfall has been especially heavy over this area that includes southeastern Bangladesh, northeastern India and western Burma (Myanmar). This disaster follows quickly on the heels of deadly cyclone Mora which hit the same area a couple weeks ago.
This rainfall analysis was made at Goddard Space Flight Center using NASA's near-real time Integrated Multi-satelliE Retrievals for GPM (IMERG) data. Those IMERG data were assembled during the period from June 12-14, 2017. The heaviest rainfall accumulation estimates (purple) by IMERG were located over southeastern Bangladesh. IMERG estimates indicated that landslide inducing rainfall totals there were greater than 510 mm (20 inches). Monsoon rainfall is expected to continue to affect the area. IMERG rainfall totals have been adjusted to reflect observed values in other similar extreme rainfall events.
