The 747 is a real beauty to land in a strong crosswind. However, if the runway is at all wet, be very very careful. I landed in LEJ a couple years ago with something around 40 knots direct cross and rolling down the runway, you could feel the plane being pushed sideways across the runway. That was the first time I actually felt out of control.
The side slipping on the runway didn't stop until about 30 knots.
Next time, I'll go hold for 20 mins.
