an easy day at the hubs, with the disruption booked for Friday and a crosswind ramp tomorrow

Today is the easy day, and that is itself the planning signal. The American convective risk is Marginal only — northern Utah hail and eastern Ohio Valley wet downbursts — while the event that matters for hub banks is the Slight, 15 percent excessive-rain risk Friday Sep 18 over the Upper Midwest, expanding to the Great Lakes, Ohio Valley and Northeast over the weekend, with Philadelphia turning wet Sep 20–21. Across the Pacific, TD 24W's ramp to typhoon strength Friday is a trans-Pacific flight-planning and fuel-load question, and a Guam–Saipan sector question if it reaches tropical-storm strength, even with no watches for the main Marianas. On the Adriatic a wind ramp to 10.0 m/s on Sep 17 is a crosswind item at the coastal airports. Europe is clean: no alert at all on Italy's bulletin. (Adriatic figures are internal situational context.)
