Millions across the southern U.S. are grappling with a major winter storm that has left record-breaking snow, sleet, and ice in its wake. The storm began over Texas and is now advancing eastward, impacting states such as Louisiana, Florida, and the Carolinas. Meteorologists estimate around 40 million people are currently under weather warnings, with more than 21 million under winter storm advisories, as reported by AP News.

The National Weather Service projects significant snowfall totals ranging from 3 to 7 inches (7.5 to 15 cm) across southern Mississippi and southeast Louisiana, with cities like New Orleans reporting up to 10 inches (25 cm) of snow, setting a new record. This surpasses the previous record of 2.7 inches (6.8 cm) set back in 1963. Similar conditions are expected in the Florida Panhandle, where Governor Ron DeSantis announced the mobilization of snowplows, a rarity in the Sunshine State, according to Los Angeles Times.

Flight operations have been severely disrupted, particularly at Houston and New Orleans airports, with nearly 2,300 flight cancellations reported as hazardous conditions persist. Shoppers have rushed to local stores to stock up on essentials before the storm hits, while officials urge residents to stay home and avoid unnecessary travel. Warnings of possible power outages due to ice accumulation have been issued in many areas, as stated by CBS News.

Despite the challenges, many residents are making the most of the rare snowfall. In New Orleans, residents celebrated with snowball fights and impromptu sledding events, creating a festive atmosphere unusual for a city typically accustomed to hurricane evacuations. "This is a white-out in New Orleans, this is a snow-a-cane," remarked one local, as social media buzzes with images of urban skiing and joyful gatherings amid the snow.

The storm has also prompted states of emergency in several southern governors' offices as they prepare for ongoing winter conditions, which are expected to continue impacting travel and daily activities across the east coast through the week. Fatalities have been reported in connection with the storm, raising concerns about safety amid the extreme temperatures.

As the storm progresses, it highlights the changing climate patterns affecting the U.S., showcasing that the deep south can also face severe winter weather, a phenomenon that was once considered nearly unthinkable. The nationwide implications of such weather demand attention and readiness, pushing states to rethink their preparedness for extreme winter conditions.
