This shows the setup well. The high is in orange, the trof is in blue at the top. You can see the high nosing out over Florida:

Thanks good map..but same question...why north? It's not "falling" into that trough...why wouldn't it just keep going west north west toward Louisiana?

Hurricanes don’t steer themselves, they react to weather patterns around them. Once the high noses out, the trof to the north becomes the dominant steering force and basically pulls the hurricane towards it. Think of a tarp suspended in air with a stone in the middle. Roll a marble. The marble will roll down towards the cone created by the stone.
