Millions of Americans are preparing for a potentially catastrophic ice storm set to sweep across the country, threatening widespread power outages and significant travel disruption. Forecasters warn that the severe weather, expected to begin on Friday and last through the weekend, could crush trees and power lines from New Mexico to the Carolinas, leaving communities without electricity for days.
Meanwhile, northern states stretching to New England are forecast to receive enough snow to render travel almost impossible. The National Weather Service confirmed that an estimated 100 million people were already under some form of winter weather alert on Wednesday.
The storm is also predicted to bring heavy snow, freezing rain, and sleet, with an "atmospheric river" of moisture anticipated to pull precipitation across Texas, Gulf Coast states, Georgia, and the Carolinas.
Here's a look at the approaching storm and how people are preparing for it, by the numbers:
The number of snowplows owned by the city of Jackson, Mississippi, where a mix of ice and sleet is possible this weekend. The city uses other heavy machinery like skid steers and small excavators to clear roads, said James Caldwell, deputy director of public works. Jackson also has three trucks that carry salt and sand to spread across roads before freezing weather.
0.5
The amount of ice — half an inch, or 1.27 centimeters — that can lead to a crippling ice storm, toppling trees and power lines to create widespread and long-lasting power outages. The latest forecasts from the National Weather Service warn of the potential for a half-inch of ice or more for many areas, including parts of Arkansas, Louisiana, Alabama, and Tennessee.

The number of Nashville snowplows named after country music legend and Tennessee native Dolly Parton (Dolly Plowton). Another snowplow in East Tennessee was named Snowlene after her classic hit song “Jolene” as part of a 2022 naming contest.

The number of layers needed to keep warm in extreme cold. AP video journalist Mark Vancleave in Minnesota explains the benefits of all three — a base layer, a middle layer and an outer shell — in this video.

The number of major U.S. hub airports in the path of the southern storm this weekend, when ice, sleet and snow could delay passengers and cargo: Dallas-Fort Worth; Atlanta; Memphis, Tennessee, and Charlotte, North Carolina. Still more major airports on the East Coast could see delays later, as the storm barrels east.
12
The number of inches of snow that could fall in parts of Oklahoma.
“You’ve got to be very weather aware, and real smart about what you’re doing,” said Charles Daniel, who drives a semitrailer across western Oklahoma.
"One mistake can literally kill somebody, so you have to use your head,” he added.
15
The number of snow and ice removal trucks operated by Memphis, Tennessee's Division of Public Works. The city also has six trucks that spread brine, a mixture designed to melt wintry precipitation. Statewide, the Tennessee Department of Transportation has 851 salt trucks and 634 brine trucks, and most of the salt trucks double as plows.
19
Parts of at least 19 states in the storm’s path were under winter storm watches by late Wednesday, with more watches and warnings expected as the system approaches. They include Texas, New Mexico, Oklahoma, Kansas, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Georgia, Tennessee, North Carolina, South Carolina, Kentucky, Indiana, Illinois, Ohio, Virginia and West Virginia.
An estimated 55 million people are included in these winter storm watches, the weather service said.
32
The degree in Fahrenheit when water freezes, equivalent to 0 Celsius. This is a magic number when it comes to winter weather, said Eric Guillot, a scientist at the National Weather Service. If the temperature is slightly above 32, it will be mostly liquid. But the colder it is below the mark, the more efficiently precipitation will freeze.
45
The number of snowplow trucks at the ready in Nashville, Tennessee, according to the Nashville Department of Transportation and Multimodal Infrastructure.
50 Below Zero
The windchill value — how cold it feels to a person when winds are factored in — that is expected in parts of the Northern Plains, the weather service projects. That equates to minus 45.6 Celsius and is forecast for parts of northern Minnesota and North Dakota.
"When the weather forecast says, ‘feels like negative 34,’ it’s just a matter of covering skin and being prepared for it,” said Nils Anderson, who owns Duluth Gear Exchange, an outdoor equipment store in Duluth, Minnesota.
330
The number of snowplows in the city of Chicago, where annual snowfall averages 37 to 39 inches (0.94 to 0.99 meters). The city also has 40 4x4 vehicles, and about 12 beet juice-dispensing trucks, according to Cole Stallard, Chicago's commissioner of Streets and Sanitation. The natural sugars of beet juice lower the freezing point of water, allowing salt mixtures to work at much lower temperatures and preventing refreezing, while also helping salt stick to the road longer.
600
The number of miles added last year to snowplow routes in Nashville, Tennessee. That was done "to get deeper into our neighborhoods — roads that had never been plowed before,” said Alex Apple, a spokesperson for Nashville Mayor Freddie O’Connell.
1,000-plus
Texas has this number of pieces of winter weather equipment, including snowplows, motor graders and brine tankers, Texas Department of Transportation spokesperson Adam Hammons said. He said the agency also works with state partners and contractors to get more equipment when needed. In the Dallas area, "right now our main focus is treating our roadways in advance of the storm,” agency spokesperson Tony Hartzel said Wednesday.
78,000
The number of cubic yards of salt on hand at the Arkansas Department of Transportation. The state has 121 salt houses around the Arkansas, plus 600 salt spreaders and 700 snowplows, said Dave Parker, an agency spokesperson.
