Typhoon Lan caused flooding, landslides and the death of at least seven people when it hit Japan early Monday morning. The powerful typhoon was accompanied by high winds and extremely heavy rainfall. Rain totals of 800 mm (31.5 inches) were reported in parts of south central Honshu. Wind speeds of over 106 kts (121.9 mph) were also reported. On October 22, 2017 at 0556 UTC the "core" satellite of the Global Precipitation Measurement (GPM) mission had an excellent view of Lan as the typhoon was approaching Japan. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation

Tropical depression twenty five (TD25W) formed in the western Pacific Ocean west of Yap on October 15, 2017. After that the intensifying tropical cyclone moved into the Philippine Sea. Tropical storm Lan recently moved toward the north and was upgraded to typhoon Lan. Maximum sustained wind speeds today (October 19, 2017) were estimated to have reached 75 kts (~86 mph). This wind speed makes it a category one on the Saffir-Simpson hurricane wind scale. Extremely warm ocean waters (30-31 degrees Celsius) along Lan's path are providing fuel for further intensification. On October 18, 2017 at

On October 17, 2017 at 0806 UTC the GPM core observatory satellite passed above a low pressure center in the western Bay Of Bengal where a tropical cyclone is probably forming. Warm sea surface temperatures in the Bay Of Bengal are supplying the necessary energy but moderate vertical wind shear observed to the south of the low are counteracting tropical cyclone development. Rainfall rates within the potential tropical cyclone were estimated using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. Extremely heavy rainfall accompanied strong

The GPM core observatory passed directly above hurricane Ophelia on October 14, 2017 at 1656 UTC. Ophelia was a powerful category three on the Saffir-Simpson hurricane wind scale with sustained winds of close to 115 mph (100 kts). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data showing the locations of extremely heavy rainfall with the hurricane. GPM's radar unveiled intense downpours in the northeastern side of Ophelia's eye that were dropping rain at the extreme rate of over 8.4 inches (213 mm) per hour. Other intense feeder bands with
