Storm-relative view
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 (11:56–12:34 UTC): flight-level RMW estimate 36 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
Pass 2 (12:34–13:44 UTC): flight-level RMW estimate 42 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis
Pass 3 (13:44–14:56 UTC): flight-level RMW estimate 8 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 4 (14:56–15:41 UTC): flight-level RMW estimate 25 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
