It just keeps getting worse & worse!
Early morning explosion
Adding to the scenes of chaos in New Orleans, an explosion rocked a chemical storage facility near the Mississippi River east of the French Quarter at 4:35 a.m., Lt. Michael Francis of the Harbor Police said. Several smaller blasts followed and then acrid, black smoke that could be seen even in the dark. The vibrations were felt all the way downtown.
Several railroad cars reportedly blew up, but NBC reporters near the scene said they were told that whatever was burning was not toxic.
The facility is near a residential area. At least two police boats were at the scene.
A fire was also consuming an office building in downtown. No fire crews were at the area, which appeared to have been abandoned.
While floodwaters in the city appeared to stabilize, efforts continued to plug three breaches that had opened up in the levee system that protects this below-sea-level city.
Helicopters dropped sandbags into the breach and pilings were being pounded into the mouth of the canal Thursday to close its connection to Lake Pontchartrain.

At New Orleans' airport, hundreds waited their turn for medical attention at the largest triage center in U.S. history. NBC's Kerry Sanders spent the night there, waking up to find two others next to him had passed away.
Rapes, beatings and armed robberies were reported in parts of the city, and Gov. Kathleen Blanco issued a warning to lawbreakers: Hundreds of National Guard troops hardened on the battlefield in Iraq have landed in New Orleans.
