IMERG Shows Heavy Rainfall From Southwest India To Northeast India
In the past couple weeks rainfall has had a significant impact on Sri Lanka, southwestern India, Bangladesh and eastern India. Monsoon rainfall caused widespread flooding, devastating mudslides and displacements of many thousands of people in Sri Lanka. Over 200 people's deaths have now been attributed to this disaster. Then cyclone Mora formed in the Bay Of Bengal on May 27, 2017. Heavy rain from Mora and it's remnants moved over southeastern Bangladesh and northeastern India. Monsoon rainfall also started to move into southern India.
This rainfall analysis was derived from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data. Total rainfall accumulation is depicted for the period from May 24 to early June 1, 2017 using estimates from IMERG data collected in near real time. IMERG data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the GPM Core Observatory as well as rain gauge networks around the world. The heaviest rainfall during this period accompanied cyclone Mora. The maximum rainfall estimates with Mora were over the open waters of the Bay Of Bengal south of Bangladesh. IMERG estimates indicated that more than 1166 mm (45 inches) of rain fell in that area. Over 381mm (15 inches) of rain contributed to the disaster over southern Sri Lanka. Heavy monsoon rainfall is shown moving into southwestern India.
