Slidell is in St. Tammany parish and they have catastrophic damage.
Mandeville and Covington were better off.
I found this on the St. Tammany webpage.

While we are readying our schools to reopen and essential services are being restored in our parish, we know a substantial number of you will be living outside St Tammany. Until our students return, we recommend that parents enroll students in schools where they are temporarily residing, if possible. In addition, we hope parents will encourage and help students study in current locations.
