Isaac Update: 10PM Sunday Evening
Not surprisingly, the 10:00 PM update to the National Hurricane Center’s forecast track continues the trend of being shifted even further west with progressive updates to come more in line with the bulk of the models.
A hurricane warning remains in effect for sections of the Northern Gulf Coast, including Pensacola, Mobile, and New Orleans.
It is still uncertain exactly where Isaac will ultimately land, but it is looking more likely that landfall will occur west of Mobile, possibly directly impacting New Orleans as category one or two hurricane. This scenario would keep direct impacts on the Tennessee Valley minimal. The thing to remember though, is that Isaac is a large storm area-wise, and its effects will be felt well away from the storm’s center. Mobile is still under a threat for hurricane force winds and storm surge over two feet.
The bottom line for the Tennessee Valley is not out of the woods by any means, but its looking less likely that we’ll see the extreme rainfall totals that appeared possible about 24 hours ago.
