Hello CliffH,
We have been praying for all the areas hit by Harvey. We hope all is well with you and yours.
It's just past a year ago when all the flooding happened here where we live and Baton Rouge area and that storm wasn't even big enough to rate a name, but it moved slowly and kept stalling, so it dropped an enormous amount of rain on all of us because it kept sucking up moisture from the Gulf. I've never seen so much rain, so heavy and so constant in all the years we've lived in Lafayette, which is 50 years! It never let up, so you never know with storms.
It has just been found that those concrete barriers, on the freeways, that are solid, kept water from moving like it should have to shed a lot of water in the Baton Rouge and surrounding area, but there were no barriers in our area and the flooding was horrendous in some places. In the Baton Rouge area, there is a convergence of four, or five rivers in the area and they all went out of their banks. That sure doesn't help things. I don't know why it is that "planners" never seem to think outside the box to think about what would happen in severe weather conditions, but they evidently don't.
God be with you and yours,
noss & MIke
