Pretty simple.

Check every-day, reserve, and vehicle clothing to make sure there are, present, clean, in good condition:
Rain jacket with hood.
Rain pants.
Poly fleece jacket
Poly pants
gloves
socks
rain/sun hat
insulating watch cap similar.

In the house check reserve appliances for function:
Propane single-burner stove
Propane heater
Propane lantern

8 or more one pound bottles propane on hand and full (by weight).

Pots with lids, coffee pot (percolator), mantles, spare gaskets, etcetera on hand, in good condition, and accessible.

This is also a good time to inventory and evaluate FAK and survival kits.
