They do go away from North America all the time! It just depends on when they become hurricanes.
Most hurricanes start out as little low pressure systems over the Sahara desert then if the conditions are just right [including they didn't take any dust with them, and there is not alot of wind sheer, (forces of wind at the top going a different way than the storm itself) and the water temperature is warm enuogh (80 degrees farinheit or warmer)] their pressure will drop [to about 1010 MB (regular sea pressure is about 1013 MB)] causing them to become a Tropical Depression which then can become a Tropical Storm then a Hurricane.
If they become hurricanes closer to Africa chances are it will miss North America all together. But the closer it is to North America the higher the chances are that it will hit North America.
Hope that explains it.

They do. You are simply too absorbed in our country to realize that lots of places have it worse off. We get 2 good storms and all of the sudden we are a victim. Do me a favor and move to indonesia and then complain about America's weather.
Referring to El Nino (don't want to bother with the tilde), It is caused roughly every 5 years. It is a result of warm water crossing the pacific ocean due to winds over the pacific, and flowing back due to the inexplicable cessation of said winds. As the warm water passes back by Hawaii and towards California, it normally forms a storm system which hits china, and we get a dry season. As previously stated, every 5 or so years, the warm mass of water stays in China and the storm system comes here. When the storm goes to china, it is called La Nina. (again, no tilde power for me)
Referring to Katrina and Rita, this is related to the Gulf Stream. The gulf stream is a warm water current that begins north of Cuba, and flows up to roughly the latitude of Iceland, which is the reason why Europe enjoys a much warmer climate than Canada, even though they receive roughly the same amount of solar energy. As this warm water flows away from the Caribbean, temperature pand pressure differences provide an ideal atmosphere for tropical storms on occasion. We just happen to have had a particularly bad season.
PS Though I use the term "Warm water" often, it does not mean necessarily "warm" as you might think. It is simply relatively warm compared to the rest of the water around it.

They persist with the steerage currents and that they are predominantly aiming in the direction of needed united statesa. and the US. that's unusual yet there have been hurricanes that have long previous directly to the northern coast of South united statesa.. as an occasion, in 1993, typhoon Bret hit Venezuela. yet another in 1933 hit Venezuela. those come from the national typhoon middle's checklist of maximum threatening. i'm beneficial there are others yet i won't be able to look to load the historic song checklist.

They do, and, hence we never hear about the ones that blow away from the U.S.A.
