Typhoon Zeb, known in the Philippines as Typhoon Iliang, was a powerful typhoon that struck the island of Luzon in October 1998. It is tied with Cyclone Ron and Susan in terms of minimum pressure, for the most intense tropical cyclone worldwide for 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 km/h (180 mph). 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.
