OMG

We have a blizzard warning.... 10" of snow by morning and another 5" tomorrow..... and 40 mph winds.....
How in the heck am I going to let Tucker and Sophie outside to potty in this? They have been doing so well going outside, I don't want to use the potty pads again....
I plan on shoveling a path from the back door, down the deck and a small area in the yard, but with the winds, I am afraid the snow will blow over on them...
Any advice? Suggestions? Safety precautions?
