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. As slow moving thunderstorms developed over the Baton Rouge metro, high rainfall rates quickly overcame local drainage capacity of wet grounds, resulting in flash flooding.
