Pass 1 (11:14–11:56 UTC): flight-level RMW estimate 62 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
Pass 2 (11:56–13:39 UTC): flight-level RMW estimate 22 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis
Pass 3 (13:39–15:09 UTC): flight-level RMW estimate 16 nm (distance of the peak 10-s flight-level wind, SE) — an estimate, not an analysis
Pass 4 (15:09–16:39 UTC): flight-level RMW estimate 13 nm (distance of the peak 10-s flight-level wind, NW) — an estimate, not an analysis
