Quick
Sudden
If you stand in the wind it will be really quick to knock you over. So quick that you probably won't even know the wind did it. You'll end up standing up only to be knocked over again, just as quick.

さっ, はやて

That quick wind is quicker than you can say Satsuki (さつ). And "Satsuki" is a pretty quick sounding name already. Go ahead, say "Satsuki" as quick as you can right now. Heck, try it a few times.
