Clearly, typhoons must be banned...
Seriously, though, a storm of that magnitude will likely carry a 20-25 foot surge over the island, topped by 30-50 foot waves. The entire geography of Wake Island will be forever altered. Hopefully the runway will survive, but don't count on it.
At least they got everyone out in time.
This is an island isolated in the deep ocean -
You don't get nearly the water piling up in a surge like you do in the Gulf of Mexico, with shallows extending dozens of miles off the coast - you go right outside the reef at Wake and you've got a cliff of thousands of feet.
The surge won't be nearly as high as it would be on the US Gulf or East Coasts, and the fringing reef will break up a lot of the wave action.
