Track colored by flight-level wind, as on the map above.
Pass 1 (05:04–05:48 UTC): flight-level RMW estimate 90 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 2 (05:48–07:34 UTC): flight-level RMW estimate 94 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis
Pass 3 (07:34–08:52 UTC): flight-level RMW estimate 82 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis
Pass 4 (08:52–09:37 UTC): flight-level RMW estimate 83 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
