Yup - I'm in HKG right now.
All flights Ex-HKG scheduled after 6 today have been cancelled.
Flights for "local" carriers before 6 are operating as normal.
Inbound International flights have been "advised against" if they were due to land any time after this morning.
The storm is slowly dying down (it was a "Super Typhoon" yesterday, downgraded to a "Severe Typhoon" today (250km/hr down to 175km/hr) but the place is ready to get battered by the elements and its approach towards us is gaining speed...
The airport floor/hotel seems to be VERY busy right now...
