Peak 10-s flight-level wind, per passDropsonde splash pointEstimated 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 (22:14–22:50 UTC): flight-level RMW estimate 70 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 2 (22:50–23:53 UTC): flight-level RMW estimate 96 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis
Pass 3 (23:53–00:52 UTC): flight-level RMW estimate 11 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis
Pass 4 (00:52–01:55 UTC): flight-level RMW estimate 127 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
