Hello David,
First, my thoughts and prayers are with you and all those about you!
It may be a long shot, but the electronics may be salvageable. I'm not too sure, but since the components are air tight then they should be water tight also. Dismantle as much as possible and flush out all the silt and salt with plenty of fresh water. Use reagent grade methanol or isopropyl alcohol to flush/rinse out the water and blow dry with canned air. Water damage should clean up far easier than heat and smoke damage I would expect!!! Once the units are cleaned up you can decide whether sending them back to the manufacturer(s) for inspection/repair is worthwhile...
Don't give up hope just yet!!!
