Wear clothes that wick fluid away from your body instead of fabrics like cotton, which soaks up water and retains it. Wool and some synthetic fabrics are better at pulling moisture away from the body and moving it to the outer surface to evaporate.
Invest in a waterproof winter jacket and pants.
Get the proper footwear, water-resistant tall boots are best.
Wear thermal gloves.
Practice slip-prevention.
Find a small enclosed area, as heat will be harder to conserve in larger spaces.
Put rugs on the floor
Close curtains.
Close doors.
Cover cracks in doors with towels.
Collect plastic bags. You will need to keep your clothing and bedding dry and protected from the elements. Plastic bags of all sizes will help you keep your possessions in good shape, no matter the weather. You can even use them as a liner to help keep your feet warmer (and prevent your boots from getting damp with sweat). Try to find a big one to use as a poncho so your outer layer doesn't get wet in rain or snow.
Use bubble rap to cover windows
Spend most of your time upstairs (If possible.)
Use scrap cardboard pieces and other synthetic layers to insulate and keep your living space dry.
Use any and everything to create barriers in your living space to prevent wind flow.
