Ask The Weatherman for August 16, 2013:
Question: Why is the northeast side of a tropical system the worst area to be in?
Answer: When we talk about tropical, we always refer to the right side at landfall. The reason is that the winds are from a direction that will always blow water on shore in the form of storm surge. Along with that there is strong turning in that portion which leads to higher tornado potential.
