Environmental history across Bertha'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.
