No. There is very little association between intensity (either
measured by maximum sustained winds or by central pressure) and size
(either measured by radius of 15 m/s [gale force] winds or the radius of
the outer closed isobar) (Weatherford and Gray 1988). Hurricane Andrew is
a good example of a very intense tropical cyclone (922 mb central pressure
and 64 m/s (125 kt) sustained winds at landfall in Florida) that was also
relatively small (15 m/s winds extended out only about 150 km from the
center). Weatherford and Gray (1988) also showed that changes of both
intensity and size are essentially independent of one another.
