Solar panels...and wind

We are currently in a situation with an imminent blizzard - it's just picking up steam now. We are expecting 70 MPH wind gusts and sustained winds of 30-40+ for about the next 18-24 hours. Northeast USA. Oh - and we're expecting 2' of snow too, and maybe more. Fun.

So I'm a little worried about my panels; should I be? Is there any chance they could blow off? The storm is a nor'easter and the panels are on the south and west roofs so not getting direct hits, but still...

This is my first winter with them, so I have no idea how sturdy they are. There are no trees nearby so the chance of a flying limb is low but I suppose not impossible.

Being buried under 2' of snow means they won't be producing much for the next little while which is part of the deal, I just don't want them ruined or damaged.

Any advice or knowledge (or ideally reassurance) is appreciated. If I seem to disappear for a bit it's because we've lost power and I'll get back here when I can, but I suppose by that time I'll know if my panels have been destroyed, lol.
