- Prepare for Power Outages: Strong winds could bring down power lines, leaving some residents without heat. Have flashlights, extra blankets, and portable heaters ready in case of an outage.
- Protect Your Pipes: Let faucets drip to prevent pipes from freezing and bursting. Open cabinet doors under sinks to allow warm air to circulate.
- Check on Vulnerable Individuals: Elderly residents, children, and those with medical conditions are at higher risk during extreme cold. Make sure they have adequate heat and winter supplies.
- Keep Pets Indoors: If itโs too cold for you, itโs too cold for them. Bring pets inside and ensure they have a warm place to rest.

With subzero temperatures, bone-chilling winds, and frostbite risks, this is not just another winter cold snapโthis is a dangerous Arctic event that requires serious preparation. Officials are warning that the next 48 hours will be critical, and those caught unprepared could face severe consequences. Stay indoors, stay warm, and stay safe.
