STORM HISTORY
Rapid growth before Luzon
Zeb developed within the monsoon trough near the Caroline Islands and moved west past Guam. Its broad circulation absorbed another short-lived tropical storm as it strengthened. The archive records peak one-minute winds of 155 kt and a minimum central pressure of 900 hPa on October 13.
Known as Iliang in the Philippines, Zeb struck northern Luzon after its peak and weakened over land. It then turned north, passed along Taiwan's eastern coast and accelerated northeast through Japan. The storm became extratropical on October 18.
Rainfall across the Philippines, Taiwan and Japan
La Trinidad in Luzon recorded 1,116 millimeters of rain in one day. Floods, landslides and strong winds damaged crops and destroyed or damaged 85,844 homes across the Philippines. The saved account records 83 deaths there and damage of ₱5.375 billion in 1998 currency. Typhoon Babs struck the same region a week later.
Taiwan recorded 31 deaths and NT$4.15 billion in damage. In Japan, rainfall reached 586 millimeters on Mount Ontake, and landslides contributed to fatalities. Zeb destroyed 770 homes and flooded another 12,548 in Japan, extending the disaster beyond its Philippine landfall.

METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA's IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive's pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth's 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm's center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
