Apparently the southern carriageway of the bridge is now serviceable and back in use, so clean up crews can get to from the island. Attempts to open the western runway are being hindered by flood damage to machine rooms, baggage handling equipment, etc. Sounds like as soon as they get the main terminal serviceable flights could resume, though getting to / from the airport is going to be a nuisance. From previous experience I know that the train companies are adept at laying on buses from Rinku Town station when the railway bridge is closed due to strong winds.
