1)Bug IN. Staying put avoids most of the common causes of injury or death. If you are advised to stay in your homes, just do so. Most of the problems happen when people are out an about when told to stay put. Traffic accidents, exposure and heart attacks while shoveling snow are the most common causes of death.
2)Stock up. Have plenty of water and food. The food should have long shelf life, require no refrigeration and need little or better yet, no preparation to eat. Canned food is a good idea. Have at least a camping stove or propane cooker to prepare a few hot drinks too. Have medications for any illness or medical condition. Have plenty of battery operated lights, LED lights and lanterns. Remember that headlamps are particularly useful. Have a battery operated radio (NOAA radios in USA) to stay updated. As alternative forms of heating, wood stoves are of course a great choice, but if not possible you can have a kerosene heater such as a Keroheat or a portable propane heater such as a Mr. Heater. Rememeber to ventilate the room and have a carbon monoxide detector installed!
3)Have your House Winter Ready. Make sure your plumbing doesn’t freeze. Even when not at home, leave the heat on to at least 55F, and leave faucets running a bit of water. If you need to stay warm, you can use plastic tarp and tape to further insulate windows.
4)Even if staying put, have your car ready for winter. Antifreeze, full tank and winter car kit including chains.
5) Be Ready for winter yourself. Having several layers of clothing will keep you warmer than just a few ticker ones. Know your limitations, if you have to shovel snow, do so at a relaxed paced and take frequent breaks.
