Thanks for the concern Luther. Ben's info is spot on and Diane is in Austin. She's been offered the chance to keep working from there for the time being.
Anything facing the beach (i.e. Pass Christian, not unincorporated Harrison County - Isles, etc.) is freaking Hiroshima, only worse with regards to devastation. Brick houses blown/washed away but no bricks anywhere? No roofs, walls, appliances, clothes or shrubbery.
I don't know what I'll do but I'm pretty sure what I won't: Rebuild.
