Some of the worst flooding in over a decade is now being reported across southern Asia as a result of summer monsoon rains. So far, there have been over 240 fatalities in Nepal, India and Bangladesh since the flooding began, and up to 10 million people have been displaced by the widespread flooding. Nepal has been hit hard by flash floods and mudslides. In India, the hardest hit states are Assam and Bihar. Twenty-two of the 24 districts in Assam are reported to be under water as the Brahmaputra river continues to rise. Meanwhile, in Bangladesh the worst hit province is Sylhet where the Surma and Kushiyara rivers have flooded widespread areas. Sylhet borders the Indian state of Assam.

Since its launch in November of 1997, the Tropical Rainfall Measuring Mission satellite has been providing un-precedented estimates of rainfall over the global Tropics. Armed with both passive and active sensors, TRMM is able to cover vast areas of the Tropics where rainfall is poorly measured such as over oceans and over land areas where radar coverage is poor or lacking. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global tropics. MPA rainfall totals for the period 5-12 July 2004 are shown for southern Asia. Widespread areas of 10 inches or more (red areas) occur along southern Nepal, northern and northeastern India and northern and southeastern Bangladesh. Some of the highest totals approaching 16 inches (dark red areas) are over central Nepal at the base of the Himalayan Mountains and over the Khasi Hills near the border between province of Sylhet in Bangladesh and the state of Assam, India.

TRMM is a joint mission between NASA and the Japanese space agency JAXA.
