Track colored by flight-level wind, as on the map above. Pass 1 (17:26–18:21 UTC): flight-level RMW estimate 13 nm (distance of the peak 10-s flight-level wind, SW) — an estimate, not an analysis Pass 2 (18:21–18:57 UTC): flight-level RMW estimate 12 nm (distance of the peak 10-s flight-level wind, NE) — an estimate, not an analysis Observations along the flight From the HDOB messages, every 30 seconds. Gaps are missing values or missing messages.
