And an updated storm track…
The news here is that now Isaac is projected to drop down to a tropical storm almost as soon as it goes inland, and that’s good news. Previous tracks had it as a hurricane far more inland than this.
But its speed has dropped considerably. Eight miles an hour is a crawl. At that rate it’ll be over Southeast Louisiana forever.
They’ve closed the new Lake Borgne Surge Barrier south of Slidell.
Mary Landrieu and the New York Times say it’s Paul Ryan’s fault that the hurricane will do damage to people’s property, or something.
There are gawkers out by Lake Ponchartrain wading into the lake to see what storm surge is like, and Mitch Landrieu says they’re deranged.
The nursing home issue in New Orleans isn’t as drastic as it was seven years ago.
Jefferson Parish sheriff Newell Normand is telling the local yokels to play Parcheesi rather than riding around during the hurricane. He didn’t mention that all the drive-thru daiquiri places will be closed, which is really all he had to say.
Finally, we have this…
