12Z GFS, west even more, stalls out along the coast south of Morgan City, LA Wednesday morning. Puts New Orleans with the dirty side of the storm, and then SLOWLY moves westward in or along the coast of Louisiana.
I was looking at tide tables--and someone please correct me if I'm wrong--but the timing of landfall predicted by the GFS (00z Aug 29) would coincide closely with high tide in the New Canal (6:28 PM CDT).
~danielw: I looked at the Rigolets tides for the 28th and 29th and the 00Z arrival of Issac would be just after the High Astronomical Tide. I other words the water would pile up before and after High Tide. The tide wouldn't go out it would just get higher. This is based on the Rigolets and Lakes Bourne and Ponchartrain tides. Water gets blown into these areas and can't get out. ( Well it can get out but it ain't pretty, floods New Orleans if it goes out that way)
