a holiday Monday over the Tokyo airports, a hail day on the High Plains and a bura pulse on the Adriatic coast

The expensive decision today is a Monday bank out of Tokyo, and it has to be made on Sunday. A transitioning storm reaching Izu and Kanto from Monday afternoon with about 350 mm behind it puts the risk on Sep 21, in the middle of Silver Week, when the recovery cost of a late cancellation is at its annual worst and a proactive thin-out is cheap by comparison. On the American board the SLIGHT risk over Oklahoma and eastern Colorado is a large-hail day — a ramp and parked-aircraft problem more than an en-route one — and the flooding across the Ohio Valley into the Mid-Atlantic is a ground-access and crew-positioning problem before it is a runway one. On the Adriatic, the footprint's forecast bura pulse to about 80 km/h at the Velebit crossing and 54 km/h at Dubrovnik Airport is a crosswind-limit conversation for Sep 20-21, held here as a watch signal because no official warning is in force.
