Super Typhoon Herb was the strongest and the largest storm of 1996. Herb struck the Ryūkyū Islands, Taiwan and the People's Republic of China, causing major damage. The name Herb was used in the Western Pacific name list for the first time after the list had been revised earlier in 1996. Although the name was not retired, the Western Pacific name list was changed from English names to Asian names in 2000, so 1996 was the in fact the only occasion when the name was used (it was never used in the Atlantic Ocean or the Eastern Pacific.)

[edit] Meteorological history
The active monsoon trough that spawned Typhoons Frankie (08W) and Gloria (09W) consolidated into a third area well east of the other two to develop Tropical Depression 10W near Saipan on July 23. It moved northward at first, then westward in response to the subtropical ridge to its north. Tropical Depression 10W was upgraded to Tropical Storm Herb on July 24. Tropical Storm Herb moved west, growing in size and strengthening to Typhoon Herb on July 25 before 48 hours later reaching Category 4 (125 knots). An interaction with Typhoon Gloria (in what is known as the "Fujiwhara effect") saw Herb downgraded to 115 knots. Shortly afterward Herb began to intensify again, and became a Category 5 super typhoon (140 knots) on July 30. Herb also became a very large typhoon: the largest typhoon in July and the 8th largest typhoon since 1977.
Herb struck the Ryūkyū Islands and made landfall in northern Taiwan as a Category 4 Super Typhoon (130 knots) on July 31. The eye of the storm passed directly over the city of Taipei, Taiwan's capital. Herb weakened as it crossed Taiwan and then the Taiwan Strait, to make landfall in China as a strong Category 2. Herb rapidly weakened over the country, and dissipated on August 3.
