Hurricane Vs. Weather Boundary

[Jerry Prsha]

I was curious as to what happens when a cold front meets a weather depression like a hurricane.

Ike should break apart after making landfall and it's remnants stretch out over my area.

But my main question is which dictates the motion of the other? Does the pressure of the depression need to be of certain strength to stall the cold front or will the low just ride along the cold front?

It's not really the front or hurricane dictating the motion of each. Hurricanes are steered by the upper-level flow. NHC has mentioned several times about how Ike will turn north and northeast on the west side of a ridge. Usually the remnant low of a tropical system will get "picked up" by a nearby trough that's moving through the area. Otherwise, it will continue to be guided by the upper-level flow (generally a ridge that the tropical system is moving around)

In this case, the remnants of Ike are expected to get absorbed by a front. It's similar to how a surface low might form and then propagate northeast along the frontal boundary.
