A: They knew weather was coming well before the race was started that may or may not effect the outcome of the only means of transport within regulations getting to a Hospital
B: Why the race was allowed to start with this being the case.
The direction of a typhoon can and does vary (as recent experience shows here in the Philippines, where several different agencies had Typhoon Ruby charting wildly different tracks across the Philippines)... the speed... does not.
A typhoon will never speed up after landfall. So the organizers knew enough about the typhoon to know that strong winds that would prevent helicopter flight (and, obviously... racing itself... any wind strong enough to endanger a chopper would make a mess of the race) would not come within the time window for the race. What they wanted to avoid was the rain.
Heavy fog at the hospital can occur whether or not there's a typhoon. There's not always a direct correlation between the two.
