re: Baton Rouge Homes At Risk from Hurricane Storm Surge

As others have said, this scenario is not indicating that storm surge itself would reach the metro BR area. The storm surge hitting Maurepas and Manchac would increase the water levels there. This would mean Tickfaw, Diversion, Blind River and the Amite River could not drain properly. Which means their tributaries could not drain properly. So on and so forth.

When this happens, water that would normally collect and discharge through the area naturally would instead back up into residential areas that stretched all the way to Baton Rouge. More than likely Ascension, Livingston and Tangi (perhaps St Helena) would be impacted by widespread standing water and significant flooding throughout their Parishes.

You have to view rain and storm events in a different way. The rain and wind and tornadoes are very dangerous, but storm surge can restrict the natural drainage and hydrology of the area which makes the rain event that comes with a Hurricane or major storm system even more dangerous.
