145 mph windspeed equals what Andrew was at landfall. Andrew was a good deal deeper (lower pressure though). Andrew had a 922mb low at landfall.
A year ago they decided that Andrew was actually a Cat 5 at landfall with wind speeds of 165 mph. But anytime the storm gets up to a Cat 4 you've got big, big trouble brewing.
I should add that Andrew was later classified a Cat 5 with estimated 165 mph sustained winds. It was a bit stronger than this storm, but when the massive surge is combined to 145mph sustained winds... few people in the track will know the difference.
