SHIPS coverage: 27 of 27 tropical or subtropical 6-hourly fixes (100%)

Category 3105 kt peakRI: +35 kt in 24 h beginning 10/15 06Z

Final position 19.5°N 108.0°W · last moving N at 2 kt · final pressure 1005 mb · final advisory 27, 2026-10-20 03:00 UTC

Rapid intensification

+35 kt/24 h peak — 2026-10-14 06:00 UTC to 2026-10-16 06:00 UTC (40 → 105 kt, +65 kt across the episode)

Based on preliminary operational best-track data. NHC's post-season reanalysis can revise a storm's wind history — in marginal cases, this could change whether the storm still meets the RI threshold.

Environmental history across Trudy's recorded life. Shaded band(s) mark the same rapid-intensification episode(s) shown in the RI badge above (identical computation, ≥30 kt/24 h merged episodes from best track). Shaded span covers all qualifying 24 h windows, so it can extend past the intensity peak. The SHIPS-RII lane is the forecast probability issued at each cycle, not an observed value. The aircraft lane shows each aircraft fix (observation) of minimum sea-level pressure, from NHC's ATCF fix file; it is not the best track.Hover to inspect any moment across every lane at once.
