STORM HISTORY
Development near Palau
Nancy's track begins on 21 November near 11.3°N, 133.2°E. It moved northwest for two days, then turned north east of the Philippines. During this turn, the cyclone strengthened from tropical-storm winds into an intense typhoon.
A brief Category 5 peak
At 18:00 UTC on 24 November, Nancy reached its archived maximum of 140 kt in one-minute sustained winds. Its minimum pressure of 920 hPa first appears six hours earlier. The track then bends northeast, away from the Philippines and into the open Pacific.
Nancy weakened during the northeastward leg. The last tropical-stage observation falls at 15:00 UTC on 26 November, and the final archived position follows three hours later.

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.
