"Pressure is up another MB to 904MB"
Katrina's punching into drier air, and some of the inflow is over land now.
Still, the southern inflow is healthy and will increase the storm's total energy budget.
I think we'll see some slight weakening before landfall, but nothing like Dennis.
Dennis fell apart and had an eyewall cycle right as it hit land.
I hope this one does the same, but it's going ashore as a CAT 5.
