Katrina made landfall around 0600 CDT Monday morning, south of Empire, LA, crossed the bay and made landfall at Pearlington, Miss. at 1 PM Monday.
The first levee breach occurred at 0100 Tuesday morning at the 17th St. Levee. Somewhere towards mid afternoon Tuesday (IIRC), it became clear that efforts to seal the breaches were failing, and the Mayor ordered the total evacuation of the city.
Thank you for clarifying that information, very helpful.
Did you get that Howlin?
