Typhoon Vongfong formed on October 2, 2014 southeast of Guam. Typhoon Phanfone, that recently pummeled Japan, formed near the same area in the western Pacific Ocean. Vongfong had wind speeds of about 120 kts (138 mph) when the TRMM satellite flew above the intensifying typhoon's eye on October 7, 2014 at 0800 UTC. TRMM's Precipitation Radar (PR) showed that powerful storms in Vongfong's eye wall were producing very heavy rainfall. TRMM's Microwave Imager (TMI) show that multiple rain bands spiraling into Vongfong were also dropping rain over a large area.

Vongfong is predicted by the Joint Typhoon Warning Center (JTWC) to have sustained winds of 135 kts (155 kts) tomorrow making it a dangerous super typhoon. The JTWC predicts that after that Vongong is predicted to weaken slightly while moving toward the islands of southern Japan.
