10 Nov, 23:54 UTChypothesisanalysis (incident.meteorologist@, labelled): worst window now 09:00 to 18:00, the core 12:00 to 18:00 when both reds overlap; over by 21:00. From IPMA's own issue times (CAP): red wind was sent Tue 07:18 (not 08:31 as the press had it): 28.7 h ahead; red rain 19.5 h; the move to 09:00, 11.6 h

10 Nov, 19:05 UTChypothesisanalysis (incident.meteorologist@, labelled): worst window Wed 12:00 to 18:00, peak most likely ~15:00 to 19:00 around the wind's swing to north-west, easing but dangerous to 21:00; red wind was known ~27.5 h ahead; confidence medium on the window, low on the peak
