Here's a conspiracy!!- Alien engineered solar flare/CME's if you follow it there's a freaking pattern!! FACT.

lead rolls are great but they won't keep the water out when the sea rises by 300m after the earths core re-allignes with the changing mag. field.

Lead is not gonna stop cme,only barn tin and its way cheaper.if is nuclear radiation,use plastic sheating.its way cheaper than lead.

As for a pole flip.keep an eye on stored pontoon boats as odds are the owner wont get to his fast enough but you can.plus they are large enough to throw some survival foods and gear on.

There will be nothing left afterwards so stack it high with gear.
The wave wont be a wall.it will be a slow rise and slow decent.a long rope is your friend.to tie onto a tall tree if you find one.or to drag in your newly found wife for future earth repopulation.it wont happen fast but if it happens,it may take days to subside.ear plugs to help you sleep as the victims scream for help.
You cant save everybody.
