If you do nothing else:
- Listen to local area radio, NOAA radio or TV stations for the latest information and updates.
- Be prepared to evacuate if you lose power or heat and know your routes and destinations. Find a local emergency shelter.
- Check emergency kit and replenish any items missing or in short supply, especially medications and medical supplies. Keep it nearby.
- Be sure you have ample heating fuel.
- If you have alternative heating sources, such as fireplaces, wood- or coal-burning stoves, or space heaters, be sure they are clean and in working order.
- Bring your companion animals inside and ensure that your horses and livestock have blankets if appropriate and unimpeded access to shelter, food, and non-frozen water.
