Question 9

Why is storm damage of a westward-moving hurricane generally less on the south side of the eye?

Accepted Answer

A)  It isn't. The storm surge is highest right under the eye where the atmospheric pressure is lowest. 
B)  It isn't. The hurricane winds are highest both just north and just south of the eye, less farther away.

D)  The winds are moving offshore there rather than onshore, so the debris travels over open water rather than colliding with buildings. 
E)  Winds in the left-front quadrant point most directly at the shore. They cause the greatest surge and wind effects.
