There must be a low pressure axis present for tropical cyclone formation. High pressures tend to denote fair weather and therefore it is hard for cloud tops to develop and grow which it required for tropical formation. The flow of air around high pressures systems also act to steer tropical systems. There is also a big correlation between hurricane intensity/formation and pressure gradient. The larger the gradient between the high and the low pressure the more potential there is for development of a tropical system.
If you are interested in learning a little more of the basics about tracking and forecasting areas of low and high pressure I would recommend these videos. About 20 minutes in all, but well worth it for beginners. http://www.stormjunkie.com/training/vidlearnfree.php
Lots more information here as well. http://www.stormjunkie.com/pages/trophome/trophome.php
Hope that helped some, the overall process is much more complex then what little I wrote, but those are some basics!

High pressure prevents the accumulation of moisture whereas low pressure allows it therefore low pressure systems are conducive to the formation of hurricanes.

Hurricane itself is a low pressure area.So, a low pressure area only subsequently becomes a hurricane,when it intensifies and the pressure gradient within it becomes very steep.In other words, low pressure area is the birth-place of hurricanes.
