Neighborhoods across New Orleans were inundated with floodwaters Wednesday morning, with more than 7 inches of rain falling in some areas ahead of the storm forecasters now predict will become Hurricane Barry by the end of the week.
In addition to the torrential rains, which left residents stranded or forced to rely on boats to get down flooded streets, the storm also brought lightning and thunder. Power was knocked out to 19,000 Entergy customers and a water spout was spotted over Lake Pontchartrain.
As of noon Wednesday, the extent of the damage to homes, businesses and cars was still difficult to assess.
Meanwhile, forecasts now suggest the storm could push enough of a storm surge to raise the Mississippi River to 20 feet in some parts of the metro area, higher than the lowest levees that keep it within its banks. That has never happened in the city's modern history.

118 of 120 pumps ready and manned so assume are used.
One reference to storm drains being litter clogged, that would overcome a lot of plans...…………………………
You can design a system but there are a lot of factors that can go wrong.
Bush’s fault.
Where be mah FEMA trailer?
Large portions of Orleans, St. Bernard, and Jefferson parishes are currently below sea level—and continue to sink. New Orleans is built on thousands of feet of soft sand, silt, and clay. Subsidence, or settling of the ground surface, occurs naturally due to the consolidation and oxidation of organic soils (called “marsh” in New Orleans) and local groundwater pumping. In the past, flooding and deposition of sediments from the Mississippi River counterbalanced the natural subsidence, leaving southeast Louisiana at or above sea level. However, due to major flood control structures being built upstream on the Mississippi River and levees being built around New Orleans, fresh layers of sediment are not replenishing the ground lost by subsidence.[70]
Dawg holla at ya boy!
By sucking the OIL out of the ground!
Was there trying to get to Ochsners for an appointment for the wife....Took an hour to go the first 70 miles and 4 hours for the last 15 miles trying to find routes around the flooded areas...saw many cars trying to drive through 3’-4’ water and ending up as “lily pads”...
Had passed through about 1/2” rain showers on way and didn’t realize the true scope of what had happened and what was going on - many streets running like rivers, all underpasses flooded (and most on/off ramps for I-10 are at the level of the underpasses so once the surface streets locked up, I-10 became a parking lot.
Reminds me of the infamous May 3, 1978 flood or maybe worse. That one took me hours to get home from work.
Many neighborhoods were built on garbage, think landfill. Organic material breaks down and over time subsidence happens.
From what i read, can be caused by how land, or
Seabed , very slowly, for very long time, reacts
From the weight of ice in previous ice age once
It has melted., surface will rise in one area,
And sink in another. Google “chesapeake bay
Sinking”, explanation is detailed there.
And it looks like they are in for a 3-day soaking starting today as Barry moves in...I feel for the residents who have to use the medians as “high ground” to park their vehicles and hope the water doesn’t reach them.
We’re over in Gulfport and expected to get more rain and wind but the flooding doesn’t happen in the high density areas over here (except for a Katrina or similar).
