What the reports say
Written by National Weather Service staff at the time of the event · public domain
The greater impact was from Francine���s flooding rain, though. As the north and northeastern eyewall stretched into an east-west oriented band of heavy rainfall, training storms resulted in widespread rainfall totals of 7-9��� across the parish with locally higher amounts, much of which fell over the course of just a couple hours. The heavy rain resulted in significant flash flooding across the parish, with numerous areas becoming inaccessible, and approximately over 350 homes and businesses being flooded throughout the parish, with the worst flooding reported in Norco.
Parish Emergency Manager reports rain gauge near Boutte has recorded 7.5 inches of rain the evening of the 10th. Several roads flooded with some impassible across the west bank of the parish in Paradis, Boutte, and Luling.
One home received ankle deep water in Norco. There was significant street flooding reported with some roads impassable in Norco, Destrehan and Luling. Minor street flooding was reported in St. Rose. Rain gauges measured 2 to 3 inches of rain in a very short period of time in the flooded area.
