Storm Leaves Homes Along Lake Erie Covered in Up To Three Feet of Ice

This past weekend, lakeside residents of Hamburg, New York, awoke to find their neighborhood transformed into a full-scale replica of Frozen’s ice-covered kingdom, Arendelle.

According to CNN, gale force winds produced giant waves that sprayed the houses along Lake Erie with sheets of water for two days straight, covering them in layers of ice up to three feet thick.

“It looks fake, it looks surreal,” Hamburg resident Ed Mis told CNN. “It’s dark on the inside of my house. It can be a little eerie, a little frightening.”

While the homeowners are anxious for the ice to melt, they’re also concerned about what could happen when it does.

“We’re worried about the integrity, of structure failure when it starts to melt, because of the weight on the roof,” Mis said.

He added that this is the worst ice coating he’s seen since he moved to the area eight years ago—but it’s not because they’ve had a particularly harsh winter. In fact, just the opposite is true. According to The Detroit News, warm winter temperatures have caused ice cover on the Great Lakes to drop from 67 percent in 2019 to less than 20 percent this year.

“Lake Erie typically has significant ice cover by this time of the year, and that protects the shoreline from these battering storms,” The Weather Channel’s winter weather expert Tom Niziol explained in a video.

The phenomenon has created another unforeseen issue for Hamburg’s coast, too: Tourism. The local police department posted a message on Facebook on Sunday, March 1, asking people to keep off both the “extremely unsafe and unstable” ice and people's private property.

What is Lake-Effect Snow?

As you probably guessed, you need a lake to experience lake-effect snow. The primary factor in creating lake-effect snow is a temperature difference between the lake and the air above it. Because water has a high specific heat, it warms and cools much more slowly than the air around it. All summer, the sun heats the lake, which stays warm deep into autumn. When air temperatures dip, we get the necessary temperature difference for lake-effect snow.

As the cool air passes over the lake, moisture from the water evaporates and the air directly above the surface heats up. This warm, wet air rises and condenses, quickly forming heavy clouds. The rate of change in temperature as you move up through the air is known as the "lapse rate"; the greater the lapse rate, the more unstable a system is—and the more prone it is to create weather events.

Encountering the shore only exacerbates the situation. Increased friction causes the wind to slow down and clouds to "pile up" while hills and variable topography push air up even more dramatically, causing more cooling and more condensation.

The other major factors that determine the particulars of a lake-effect snowstorm are the orientation of the wind and the specific lake. Winds blowing along the length of a lake create greater "fetch," the area of water over which the wind blows, and thus more extreme storms like the one currently pummeling the Buffalo area. The constraints of the lake itself create stark boundaries between heavy snow and just a few flurries and literal walls of snow that advance onto the shore. The southern and eastern shores of the Great Lakes are considered "snow belts" because, with winds prevailing from the northwest, these areas tend to get hit the hardest.

The One-Day Record Snowfalls In Each State

Long after you’ve grown out of believing in magic, every thick, whirling snowstorm still seems to have been cast upon your town by a winter warlock (or Frozen’s resident ice queen, Elsa).

It’s also pretty magical when those inches of stacked snowflakes add up to a message from your manager telling you not to come into the office. In southern states like Georgia or Florida, sometimes all it takes is a light dusting.

But even those characteristically balmy places have hosted some serious snowstorms over the years, and David Cusick for House Method crunched the numbers to find out which ones made the record books. Using data from the National Centers for Environmental Information, Cusick created a map showing the one-day record snowfall for each state.

Florida finished in last place with a scant total of 4 inches, which occurred in Santa Rosa County on March 6, 1954. About two years before that, on January 14, 1952, Colorado had a staggering 76 inches—that’s more than 3 inches per hour—a national record that’s remained unchallenged for nearly 70 years.

But other states have come close. The snowstorm that hit Colorado in 1952 wreaked almost as much havoc in California, whose record from the same day was 75 inches. And Washington saw 70 inches of snow in November 1955, beating its 52-inch record from 1935 by a full 18 inches.

Though Midwestern states have gained a reputation for harsh, snowy winters, their one-day record snowfalls are surprisingly moderate. The Illinois and Indiana records are 24 and 26 inches, respectively, both slightly lower than Ohio’s 30-inch snow day from 1901. In 1993, North Carolina bested Ohio’s record by 6 inches.

Wondering how your individual county’s record compares to the overall state one? Cusick created a map for that, too, which you can explore below.
