Super Typhoon Dianmu • Super Typhoon Dianmu

Super Typhoon Dianmu. The MODIS instrument onboard NASA’s Aqua satellite captured this true-color image of Super Typhoon Dianmu on June 16, 2004 at 4:15 UTC. At the time this image was taken, Dianmu was located approximately 950 miles southeast of Kadena and was packing sustained winds of 180 mph with higher gusts to 220 mph. Dianmu is expected to continue on its north-northwest path and gradually turn to the north.

Typhoon Dianmu, known in the Philippines as Typhoon Helen, was a powerful typhoon that struck southeastern Japan during the 2004 Pacific typhoon season. The name Dianmu is the name of the goddess of thunder and lightning in Chinese folklore.

Dianmu formed on June 13 and moved west-northwest where it rapidly strengthened to typhoon status on June 16. Dianmu then strengthened to a 285 km/h (180 mph) typhoon, making it one of nine typhoons to reach that intensity since 1990 and equaled its power with Typhoon Chaba as the strongest typhoons of the 2004 season. After reaching peak intensity, Dianmu turned northwest before skirting the minor Japanese islands and making landfall in Japan as a tropical storm. Dianmu then became extratropical on June 21.

Dianmu caused four fatalities and considerable damage across southern and eastern Japan.[1] Damage amounted to US$68.3 million. Two more fatalities were also reported in neighboring South Korea.
