THE READ — what this desk must decide today

a holiday-weekend flight bank into Tokyo that can still be re-cut, and a Midwest and Florida rain day that cannot

The decision this desk owns today is a pre-cancellation about a weekend that has not happened, and the storm's size is what makes it affordable. Dujuan's wind and rain strengthen from today, worst Sep 18–19, with Ogasawara Saturday, the Izu Islands Sunday, and the centre about 100 km off Boso and 180 km from central Tokyo on Monday — which puts Haneda and Narita Silver Week banks, trans-Pacific routing and fuel loads onto a rain-and-saturation question rather than a wind-limit one. A 950 km gale field means the disruption envelope is legible days out, and the re-cut is cheapest now. Today's live operational problem is American: flash flooding from the Rockies and Plains into the Upper Mississippi Valley and Midwest and a separate Florida excessive-rain threat, both hub-adjacent, with the convective picture Marginal only. In Europe, the live items have de-escalated — yellow across 12 Italian regions and orange for the Balearics alone — and the strongest coastal crosswind in the footprint set is a window maximum of 9.6 m/s at the Velebit crossing. (The Adriatic figures are internal situational context.)
