Pffft. This is simply a weak Cat 1 storm that the media is trying to hyperventilate into another Katrina for political purposes.
If I were writing the news, it would be about the much-needed rains that might be coming to the Midwest from this storm.
This hurricane will probably end up, by landfall, as a medium-high Cat 2 (the Gulf is like bathwater right now).
Your observation about Isaac sending much-needed rains right up the Mississippi Valley is spot on, too.
Any direct hit on New Orleans is serious because the city is under sea level. It’s not the winds it’s the rains. It’s the flooding. And this storm is moving slow.
