1) FIRST TO GO
Unprotected areas in Plaquemines Parish could flood first Monday.
2) THE BETSY SCENARIO
Hurricane force winds are projected to top levees in eastern New Orleans, pushing water into the 9th Ward, the Michoud area and even into Mid-City.
3) SLIDELL SOAKED
Large parts of Slidell could be inundated by 10-11 foot storm surges.
4) PUMPED-UP LAKE
Easterly winds in advance of the storm could pump water from Lake Borgne and from Breton and Chandeleur sounds into Lake Pontchartrain, raising the lake’s surface by 12 feet.
5) OVER THE TOP
Waves equal to half the surge height or more would top the surge water and could overtop levees on the south shore of Lake Pontchartrain and around Chalmette.
6) GOING ASHORE
As Katrina moves inland and the winds come from the north, the high Lake Pontchartrain waters could stream across St. Charles Parish and turn east along Airline Highway into Kenner.
Either you have lived in the area or you have a good resource because your points are on the money on what could happen. I lived there for 5 years and went through a number of hurricanes. If Katrina comes in from the east slow and the tide is up they are screwed.
The pumps will be overwhelmed and useless and knowing the way the state and local government works don't expect much help.
