I didn’t realize that the fantastic Susannah Breslin had moved to New Orleans, but I’m thankful to learn from Xeni Jardin that she’s safe. As suggested here repeatedly, donating to the Red Cross is among the best things you can do right now to help out.
At the present time, the French Quarter is battered but not broken. But as Rory notes, one of BT’s friend has reported that a levee has burst and water from Lake Pontchartrain is causing the flooding to rise. With the machinery to pump out this water now out of commission, it appears that what we all feared is now, in fact, happening. CNN reports that 80% of the city is flooded and some areas are now under 20 feet of water — much higher than the initial Katrina strike. Not good at all.
