Another one of those dumb questions (Hurricane Dean meets Chicxulub)

I was looking at an animated progression (
http://www.nhc.noaa.gov/archive/2007.../loop_5W.shtml ) of
5-day forecasts for the track of Hurricane Dean and noticed the eye may
pass directly over the center of the Chicxulub crater.

I'm a total layman and so felt eminently qualified to begin wildly
speculating on what would happen if a meteor that was 5 - 10 miles
across slammed into the eye of a Cat-5 hurricane. Surely, it would
totally destroy the hurricane, no?

But wait... Maybe it would intensify the hurricane? No, create
something like a hurricane, except a million times worse? After all,
you've got a rising, fiery hot column of air and zillions of tons of
rock vapor and other debris. Wouldn't all that start spinning just like
a hurricane does when it forms?

So apart from the initial blast, the red-hot, re-entering ejecta turning
the sky into a broiler, the massive die-offs and other unpleasantness,
wouldn't you get the most hellacious hurricane (times a million) known
to man? And it, too, like a hurricane, would set off on a journey
across the face of the earth, transporting heat away from its point of
origin? 'Course, there wouldn't be much left to destroy, but it would
be one of, perhaps, the minor effects of an big impact, no?
