Track colored by flight-level wind, as on the map above.Ferry legs beyond 100 nm not shown.
Pass 1 (23:22–23:59 UTC): flight-level RMW estimate 19 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 2 (23:59–01:13 UTC): flight-level RMW estimate 14 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
Pass 3 (01:13–02:48 UTC): flight-level RMW estimate 18 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis
Pass 4 (02:48–04:34 UTC): flight-level RMW estimate 8 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis
Pass 5 (04:34–05:17 UTC): flight-level RMW estimate 23 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
