General Science / What is the process of hurricanes creation?

I have read about the warm sea as the driving force for the hurricanes, and the Coriolis acceleration as the reason for its rotation. But I could not find a logical connection for the event as a whole. I will try below an explanation step by step, and would like to know if it makes sense, or where I can find a better one:
1) In regions of shallow waters and near the tropic parallels (Gulf of Mexico for example), the sun light is maximum in the summer. Because the sea is shallow, it warms more than the ocean nearby.
2) A lot of water evaporates from that warmed sea, and the added molecules force a displacement of the existing ones in all directions.
3) As the air pressure is lower above than sideways, most of the expansion is upwards.
4) The equilibrium outcome is a huge volume of warm air above the sea, if there are not winds to dissipate and disturb that state.
5) When the summer finishes, the sun light (the actual driving force for the expansion) in the same region weakens.
6) All that volume of air loses some temperature and its pressure drops as a consequence.
7) Air from outside moves to that region, due to the pressure difference.
Due to the Coriolis acceleration the radial winds deflect sideways
9) An hurricane is formed.
