You can also weight the tarp down with milk jugs full of water if you have no good attachment points. Tie them to the tarp grommets with line.
As far as what can go wrong? What I've heard of happening this winter, is that boats that get pushed down, due to increased water pressure, are having water backup through inboard engine water intakes, blowing the hoses off of seacocks and flooding down.
If your intakes are dry and shut, and your seacocks are shut, hoses double-clamped, you should be ok.
Also, if you make a tent over the boom, and the cockpit remains empty, the snow will pile onto the forward deck, maybe it'll raise the stern and keep most of your seacocks from being pushed deeper underwater.
