Track colored by flight-level wind, as on the map above. Pass 1 (09:22–10:02 UTC): flight-level RMW estimate 53 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis Pass 2 (10:02–10:22 UTC): flight-level RMW estimate 33 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis Observations along the flight From the HDOB messages, every 30 seconds.
