Where is most prone to hurricanes and why?

The Caribbean Sea, and Atlantic Coasts of the USA and Canada.
There are two main forces that control where a hurricane goes—the environment, and something called “beta drift”. The environment around a hurricane is the main force behind the direction the storm goes, “steering” it in one direction or another. The primary environmental steering for storms that form in the deep Atlantic tropics—these are the systems that move off Africa and spin into tropical lows—consists of the east-to-west moving trade winds, which drive storms across the Atlantic and toward the Caribbean and the Gulf of Mexico.
Other environmental factors will also influence storm motion, particularly areas of high pressure and atmospheric troughs that serve as “roadblocks,” preventing storms from encroaching upon the pressure areas. The subtropical high (also known as the Bermuda High) acts to block storms. In the case of Earl last week, as it moved into the Caribbean Sea, a large area of high pressure over the continental U.S. helped prevent the storm from curving up into the U.S. Gulf Coast. It was blocked from doing so, and therefore steered into Mexico.
The other major factor in hurricane tracking is “beta drift”. When a storm begins to spin around an central area of a storm (the eye), it creates a vortex. When this happens, Coriolis force (the force that, in the Northern Hemisphere, deflects atmospheric motion to the right of its path) causes the storm to drift, generally toward the poles. This is why most hurricane paths in the Northern Hemisphere, after they find a weakness in high pressure over the mid-latitudes, begin to curve northward and to the right.
These two factors help us predict where a hurricane will go, with some accuracy. Advancement of forecasting models, computers, and techniques in the last few years have also helped. With that said this is a somewhat simplistic view. As ever with weather, there are many other factors that must be considered with storm direction—strength of trade winds, upper air flow, sea surface temperatures, interaction with land, and others—that cause storms to sometimes take unexpected paths.

Of course southern states like florida. New orleans. Texas. The gulf of mexico. It has something to do with the jetstream

USA is always destroyed by hurricanes -.-
