I would go, if you can not cancel and reschedule I would go but note that it is the chance I would be willing to make. Chances are you will be fine based on the present predictions but it could change for the better or worse.

First thing I would do however is stock up on water and beer! Probably a bag of chips as well just in case.

I also would rent a higher ground clearance type vehicle, such as a jeep. The water along the road to and from the area you are staying from the airport can flood at times.
