No. During a replacement a storm weakens considerably. After it's over, a storm will return to its original strength if conditions around it haven't changed; if shear, dry air have increased, or the storm is passing over land, it won't restrengthen after the replacement.

I believe that would be the case only if it were over water. It's moving onto land and that will break it up, eventually...

From NOAA - Not as it's being replaced (the hurricane is acutally weakening as the formation of the new eyewall robs energy from the old one). It can, under ideal conditions, emerge at the same strength or even stronger. That's not going to happen with Katrina (at least if I'm guesstimating right based on the radar); much of it is already over land.

The way I read the radar, the north half of the eye is shrinking, while the southern half is trying to re-form at its previous size.
