While narrower, the forecast path for Issac has not changed much overnight. The question now is more one of ultimate intensity rather than location. If the storm should move over the hot water in the Gulf, then a major hurricane becomes possible.
I urge everyone in the shaded areas to continue to monitor the latest information and make preliminary low cost measures in case hurricane watches/warnings are issued. Scroll down to the Isaac posting below for some suggestions.
Regardless of intensity, Isaac will bring heavy rains to areas along its path. In some areas the rain may cause flooding, in others it will bring welcome, drenching rains. Do not focus closely on the implicit path.
