Luck of the draw
I flew through the place in Feb 82 in a tail dragger, and just missed a similar occurrence. I suspect that Dubai has considerable more tarmac everywhere now so it will only be worse. Much damage had actually been done by golf ball size hail stones that 'dappled' aircraft and cars all over.
In 82 the Airport still had a lot of sand in the location so that helped to soak up the water, but nowadays unless you provide proper storm culverts to deal with the excess then it will happen again.
