Good luck !
Best snow storm safety a family can have against the extreme cold is a plain old wood stove or even a fireplace as in your case. Second best safety is using your kitchen stove if gas and simple old style gas wall heaters..... if so always have 2 or more smoke and carbon monoxide detectors with new batteries before the storm.
We keep 90 days of canned goods, stews, soups and chili on the shelf and a dozen 6 gallon jerry jugs of potable water for general use as well as 12 cases of bottled water.
Bed tanks on the trucks are full and provide extra weight and we put tire chains on at least two of our 4x4’s if we MUST travel in the deep snow.
Whole house generator we have is plumbed to the natural gas line and powers entire home with no problem, power surges or not. A couple of honda commercial grade portable generators back the fixed unit up. As well each of our vehicles have power inverters installed if we really get in a fix.
10 face cords of hickory secured and dry around the property will get us thru the power outage, ice, snow or extreme cold weather we get here in the panhandle of texas each winter.
Again wish ya well.......stay safe !
Don’t forget to clean your chimney! I had a Chimney fire a couple of weeks ago, not fun.
