Isaac Sunday Evening Update from WTVY-TV Meteorologist Oscar Fann
Isaac has indeed moved more westward today, and this helps put more credence into Isaac's future forecast path.
(UPDATE - the new 8pm edt Aug 26 Isaac update shows this basically westward motion is continuing for now)
I think this primarily westward movement we saw today (and is still occurring) bodes well for the forecast landfall area late Tuesday for either:
1) the Louisiana / Mississippi area (the National Hurricane Center's official landfall area; or
2) south of New Orleans along the southeast Louisiana coast then slowly westward along the Louisiana coast.
