2,076 first-hand accounts of flood events in Louisiana, ranked by impact. Each is a NOAA-written narrative of the moment.
Above normal rainfall in the preceding 7 days set the stage for the potential for flash flooding as many areas had rain soaked grounds. The morning upper air sounding at KLIX showed a precipitable water value of 2.2, which is near the climatological max for this time of year.

Read the full account →A stalled boundary over the area caused thunderstorm development during the early morning hours. The storms trained along the boundary over Hammond, an urbanized area. The very moist environment led to efficient rainfall over that area, which caused isolated flash flooding.
Read the full account →During the morning of December 2nd, thunderstorms ignited along a convergent axis parallel to the upper-level flow. This set up over urbanized New Orleans, and caused flash flooding that morning.
