Typhoon Herb, known in the Philippines as Typhoon Huaning, 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 in fact the only occasion when the name was used (it was never used in the Atlantic Ocean or the Eastern Pacific.)

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 intensified into a tropical storm and was named Herb on July 24. Tropical Storm Herb moved west, growing in size and strengthening to typhoon status on July 25 before rapidly intensifying into a Category 4 48 hours later. Herb slightly weakened while it underwent a Fujiwhara interaction with Typhoon Gloria. Shortly afterward Herb began to intensify again, and became a Category 5 super typhoon on July 30, reaching its peak intensity with a barometric pressure of  and 10-minute sustained winds of . Herb also became the largest typhoon in July and one of the largest typhoons since 1977.

Herb made its first landfall on the island of Taketomi, in the Ryūkyū Islands, before its second landfall in northern Taiwan as a Category 4 on July 31. The eye of the storm passed directly over the capital, Taipei. Herb weakened as it crossed Taiwan and the Taiwan Strait, to make landfall in China as a strong Category 2. Herb rapidly weakened over the country and dissipated on August 3.

On Ishigaki Island, one home was destroyed and eighteen others were damaged. Extensive losses to agriculture, fisheries, and forestry took place across the region as well. Losses on Ishigaki alone reached ¥630 million (US$5.9 million). In Okinawa, large swells up to  flooded low-lying areas, leaving minor damage.
