You are both correct. The name of the rectangular box(s) that you are referring to is the Hebert's Box. (pronounced A-bear's Box)

Photo below shows their location. Hebert proposed that a large number of storms that passed through the Eastern Hebert Box moved west and affected Florida.
The Western Hebert Box is more seasonal, if my recall is correct, it's more of a September through October area. With the storms recurving to again affect Florida. I'll try to find a link other than the wiki.

Scottsvb is also correct in regard to the atmosphere. Weathers changes more often than the News and almost as often as a wristwatch.
Some will probably argue the wristwatch theory.
