Re: Gustav Inland in Louisiana, Hurricane Hanna moving WSW, Tropical Storm Ike Forms in Atlantic

One thing that might have weakened Hanna is that she has been sitting over one location for a day now, and the ocean heat content is fairly low there, as you can see from this image:

I'm guessing that the warm water has essentially been depleted under her, and she's being hurt by cooler deeper waters impacting her.

Just a guess, but it follows from past storms.
