what will happen to that remnant low that may loop in the gulf? will it just disappear, or could it come back to haunt us?

[Dean4Storms]

Thanks for the updates TheEuropean!

Latest 12Z CMC hooks Ida sharp right as it approaches the mouth of the Miss. Makes landfall in 36 hrs near Panama City and then weakens as it slides down the west coast of FL.
