No, no quotes. However, I did just go back and check the map and read I-4 about Shinovar, and it seems to back up the position that the highstorms cannot be continent-sized. If they were, they would easy circumvent the mountain ranges to the south or north (depending on which direction the winds blow, clockwise or counter-clockwise). Also, I am talking about far more destruction than the highstorms do. If there was truly a continental sized hurricane, the winds near the edges of the storm would have to be traveling somewhere between 500-1000 mph, depending on how large the continent is. This would be like having a storm 100-1000 times the power of Katrina every few days. It would be impossible for almost any life to survive, and simply pointing structures toward the stormwall would be useless.
Finally, the map would not have the directions East and West as Stormward and Leeward if the winds blew in a circular motion depending on where on the continent you are. I think that the book's answer, that the storms originate in the East at a place called the Origin, travel westerly through some mechanism we cannot be exactly sure of, and consistently lose strength as they travel over land, is the one that makes the most sense at the moment.
