Despite tracking just east of us, Cristobal didn’t do us much harm. We still have to wait and see if there will be any flooding, but it looks like we’ll be ok right now.
The Baton Rouge area is funny when it comes to flooding. The Mississippi River runs right by downtown, but with a very robust protection system from the levees, most people aren’t concerned about the Mississippi. The bigger threat is the Amite river, a drainage system that extends into Mississippi (the state) and is almost completely uncontrolled. It was rainfall in the Amite basin that caused extensive flooding back in 2016.
So far, the stream gages on the Amite are climbing, but it doesn’t look like Cristobal dumped enough rain to be a major concern.
The 2016 flood was caused by 20-30 inches of rain across the Amite basin. It doesn’t look like Cristobal dropped anywhere near that. A quick survey of gages shows it dropped 2-4 inches of rain in the basin. Areas further east of us received more rain and to the southeast, storm surge along with the rain led to some flooding. Cristobal is still predicted to drop up to 10" of rain in some areas and that can lead to more flooding, but it looks like we dodged another bullet. Unfortunately, the season is just getting started.
Good luck to those folks still in the path.
