Two NASA satellites provided data on clouds, rainfall and the diameter of the eye of Super Typhoon Vongfong as it turned north in the Northwestern Pacific Ocean.
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 knots (138 mph) when the Tropical Rainfall Measuring Mission or TRMM satellite flew above the intensifying typhoon's eye on October 7, 2014 at 0800 UTC (4 a.m. EDT). 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.
On Oct. 8 at 02:15 UTC (Oct. 7 at 10:15 p.m. EDT), the MODIS instrument aboard NASA's Terra satellite captured a visible image of Super Typhoon Vongfong's wide cloud extend and the storm's wide circular eye.
On Oct. 8 at 1500 UTC (11 a.m. EDT), Vongfong had maximum sustained winds near 145 knots (167 mph/268.5 kph) making it a Category 5 Super Typhoon on the Saffir-Simpson Scale. It was centered near 18.7 north and 130.7 east. It was centered about 510 nautical miles (586 miles/944.5 kph) south-southeast of Kadena Air Base, Okinawa, Japan. Vongfong was moving to the north at 7 knots (8 mph/13 kph). It was creating extremely rough seas in the Philippine Sea, with wave heights to 50 feet (15.2 meters).
According to the U.S. Kadena Airbase, on Oct. 8, a combined Japanese-U.S. Air Force rescue team recovered the body of the third Airman who had been swept out to sea on Oct. 5 from Typhoon Phanfone.
The Joint Typhoon Warning Center predicts that Vongfong is predicted to weaken slightly while moving toward the islands of southern Japan.
