Storm-relative view
Peak 10-s flight-level wind, per passEstimated centerObservations relative to the estimated storm center (best track refined by this mission’s aircraft center fixes), north up, within 150 nm; not the best track. Track colored by flight-level wind, as on the map above.
Pass 1 (05:01–05:42 UTC): flight-level RMW estimate 125 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 2 (05:42–07:23 UTC): flight-level RMW estimate 78 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
Pass 3 (07:23–08:16 UTC): flight-level RMW estimate 114 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis
