Typhoon Zeb, known in the Philippines as Typhoon Iliang, was a powerful typhoon that struck the island of Luzon in October 1998. The tenth tropical storm of the season, Zeb formed on October 10 from the monsoon trough near the Caroline Islands. It moved westward initially and quickly intensified. Zeb's inflow briefly spawned another tropical storm, which it ultimately absorbed. Developing an eye, Zeb rapidly intensified into a super typhoon, officially reaching maximum sustained winds of 205 km/h (125 mph); one warning agency estimated winds as high as 285 kilometres per hour (177 miles per hour). After reaching peak intensity, the typhoon struck northern Luzon and quickly weakened over land. Turning to the north, Zeb brushed the east coast of Taiwan at a reduced intensity, and after accelerating to the northeast it moved through Japan. It became extratropical on October 18 and moved eastward over open waters.

First affecting the Philippines, Zeb dropped torrential rainfall in Luzon, reaching 1,116 millimetres (43.9 inches) in one day in La Trinidad, estimated as a one-in-1,147-year event. The rains caused floods and landslides, which compounded with high winds to leave heavy crop damage. Zeb destroyed or damaged 85,844 houses in the Philippines, and damage in the country was estimated at ₱5.375 billion (1998 Philippine pesos, $126 million U.S. dollars), the fifth-costliest at the time. There were also 83 deaths in the country, a number compounded upon when Typhoon Babs struck the same region a week later. High winds and rainfall from Zeb later affected Taiwan, causing NT$4.15 billion (New Taiwan dollar, $125 million USD) in damage as well as 31 deaths. Gusty winds affected much of Japan, while heavy rainfall peaked at 586 mm (23.1 in) on Mount Ontake. The storm killed 14 people in the country, several related to landslides. Zeb destroyed 770 homes and flooded another 12,548 in Japan.
