Rapid intensification +65 kt/24 h peak — 2026-09-01 00:00 UTC to 2026-09-02 18:00 UTC (55 → 140 kt, +85 kt across the episode)+30 kt/24 h peak — 2026-09-04 06:00 UTC to 2026-09-05 06:00 UTC (110 → 140 kt, +30 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.

hover the chart to inspect a moment
Environmental history across Lowell'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. Satellite intensity estimates
Maximum wind (kt) estimated from satellite imagery — estimates, not observations, and not the official intensity. ADT and SATCON: UW-CIMSS, delivered through NHC’s ATCF fix files. Subjective Dvorak from the agency named on each fix.
