What to know about winter storm hitting North America

Massive Winter Storm Blair Paralyzes the US and Canada

A powerful winter storm, dubbed Storm Blair, has unleashed a wave of extreme weather across the United States and Canada, affecting millions of people with snow, ice, and freezing temperatures. Over 60 million Americans are currently under weather alerts, with forecasters warning that this could be the most severe winter storm in over a decade.

The Polar Vortex: The Storm’s Driving Force

The polar vortex, a circulation of cold, dense air around the Arctic, is driving Storm Blair. When this vortex weakens, frigid air spills southward, creating harsh winter conditions across North America. This phenomenon has led to heavy snowfalls and temperatures far below seasonal averages, with some areas experiencing a staggering drop to 12-25°F (7-14°C) below normal.

State of Emergency Declared in Multiple States

Seven US states—Kansas, Missouri, Kentucky, Virginia, West Virginia, Arkansas, and parts of New Jersey—have declared states of emergency.

• Kansas City has recorded its heaviest snowfall in 32 years, with over a foot of snow (30-40cm) blanketing the city.
• Up to 14 inches (36cm) of sleet and snow have fallen in northern Missouri, causing severe disruptions.

Impact on Daily Life and Travel

Storm Blair has brought widespread chaos:

• Travel Disruptions: According to FlightAware.com, over 1,700 flights were canceled on Sunday, and an additional 8,300 flights were delayed. Major airlines like American, Delta, Southwest, and United have waived change fees for passengers.
• Road Hazards: Conditions have deteriorated on highways, with numerous crashes reported. Near Salina, Kansas, a fire engine rolled over due to icy roads.
• Public Services: Federal offices in Washington DC will remain closed on Monday. Meanwhile, the US Congress plans to proceed with its session despite the adverse weather.

Northern Neighbors Brace for Impact

In Canada, the storm has brought equally challenging conditions:

• Freezing temperatures span much of the country, with wind chill in Manitoba expected to drop as low as -40°C.
• In Ontario, snow squalls and up to 15 inches (38cm) of snow are creating hazardous conditions.

Severe Thunderstorms in the South

Adding to the chaos, the southern states are bracing for severe thunderstorms, with potential tornadoes expected to develop in Arkansas, Louisiana, Mississippi, and Alabama. The National Weather Service (NWS) has warned of dangerous conditions, urging residents to remain vigilant.

Long-Term Outlook

Forecasters predict that temperatures could remain well below average for at least a week, making this one of the coldest Januarys since 2011. AccuWeather meteorologist Dan DePodwin warned, “This could lead to prolonged disruptions and difficult recovery efforts.”

Safety Tips During Extreme Winter Weather

To navigate the challenges posed by Storm Blair, follow these safety tips:

1. Stay Informed: Monitor weather updates through reliable sources like the NWS and local news channels.
2. Avoid Non-Essential Travel: Roads are extremely dangerous, with whiteout conditions in many areas.
3. Prepare for Power Outages: Keep flashlights, batteries, and backup power sources ready.
4. Dress Appropriately: Wear multiple layers, including hats and gloves, to protect against frostbite in sub-zero temperatures.
5. Stock Up on Supplies: Ensure you have enough food, water, and medications to last several days.
