A powerful Arctic blast has taken hold of South Dakota, sending temperatures plummeting and creating life-threatening conditions across the state. With wind chills expected to reach a staggering -45°F, the National Weather Service has issued an Extreme Cold Warning through Wednesday, February 19.
Officials are warning residents that this dangerous cold could lead to frostbite within minutes, power outages due to increased demand, and treacherous travel conditions. Staying indoors, dressing in layers, and preparing for emergencies is crucial as the state battles one of its coldest spells in years.
How Cold Will It Get?
Meteorologists say the worst of the cold is yet to come, with temperatures dropping below -20°F in many cities across South Dakota. Wind gusts will make it feel even colder, with wind chills as low as -45°F. The areas most affected include:
- Sioux Falls – Cloudy skies with temperatures falling to -19°F overnight. Highs will struggle to rise above 6°F in the coming days.
- Rapid City – Bitter cold expected, with lows reaching -22°F and highs barely reaching zero.
- Aberdeen – The most extreme conditions, with overnight temperatures plunging to -27°F and wind chills making it feel much colder.
These conditions are not just uncomfortable – they are potentially deadly. Exposure to the cold for even a short time can lead to frostbite in under 10 minutes and hypothermia if proper precautions are not taken.
Major Dangers to Watch Out For
This extreme cold comes with a variety of hazards that could put lives at risk:
- Frostbite and Hypothermia – With wind chills as low as -45°F, even a few minutes outside can cause severe skin damage. Hypothermia is a major risk, especially for the elderly, children, and those without adequate shelter.
- Power Outages – With record-breaking energy demand, the power grid may struggle to keep up, leading to potential outages. Without electricity, heating systems could fail, making homes dangerously cold.
- Travel Risks – Car batteries may fail, roads will be icy, and vehicles could break down in dangerous conditions. Officials strongly advise against unnecessary travel.
- Frozen Pipes & Home Damage – Water pipes are at high risk of freezing and bursting, causing major damage. Proper insulation and letting faucets drip can help prevent disasters.
What You Need to Do to Stay Safe
Authorities are urging everyone to take immediate action to protect themselves and their families:
- Stay indoors as much as possible. If you must go outside, wear multiple layers, including insulated gloves, thick socks, a hat, and a face covering.
- Limit travel unless absolutely necessary. If you must drive, keep an emergency kit in your car with blankets, food, and extra batteries in case you get stranded.
- Prepare for power outages. Charge all essential devices, have flashlights and backup heating sources ready, and avoid using generators indoors due to the risk of carbon monoxide poisoning.
- Protect your pets. Bring them indoors! If they must be outside for any reason, ensure they have proper shelter, warm bedding, and access to unfrozen water.
- Check on elderly relatives, neighbors, and vulnerable individuals. Make sure they have enough supplies and a safe, warm place to stay.
How Long Will This Last?
The Arctic blast will grip South Dakota through midweek, with the worst conditions expected Monday night through Wednesday morning. After that, while temperatures may slightly improve, they will remain dangerously cold for the rest of the week.
Officials stress that this is one of the most extreme cold outbreaks in recent years, and being prepared can mean the difference between life and death.
