Question about "landfall Wobbles" Land interaction

Do Hurricanes tend to wobble near the coast when they interact with land? If so which direction. Can anyone provide examples IE Katrina and past Storms?

I once heard a met give a great analogy. He said that a hurricane interacting with land is much like a spinning top interacting with a flat plane such as piece of paper. Once the top hits the paper, the friction forces the top to ricochet, stabilize itself, and then regain its forward progress.

Whatever keeps it over water longer. If a hurricane is hitting the N Gulf coast moving east of north, it will tend to move even more to the east to stay over water longer (e.g. Ivan).

If a hurricane is moving NE towards a west-facing coast, it will bend more to the north to stay over water longer (e.g. Charley dancing around Sanibel Island).

So if a hurricane is impacting the N Gulf coast moving NW, one could assume it would bend farther to the west to stay over water longer.
We've seen this occur before, such as with the remnants of Ivan when he looped around or Claudette back a few years ago.
