It Just Snowed In the Sahara Desert

The Sahara isn’t always scorching. This week, a cold spell hit the town of Aïn Séfra in northern Algeria, and the world’s largest hot desert was blanketed in up to 16 inches of the white stuff in some places, The Independent reports.

The rare snowfall began early on Sunday, January 7, with the resulting precipitation melting by late afternoon. The phenomenon marked the region’s third snowfall in nearly 40 years, with other surprise wintry events occurring in February 1979 and December 2016.

Aïn Séfra is located in the Saharan Atlas Mountains in the northern Sahara Desert. Thanks to the region’s altitude, it's “not surprising that the area would see some snow if the conditions were right” a spokesperson for the Met Office, the UK’s national weather service, told The Independent. "With the setup over Europe at the moment, which has given us cold weather over the weekend, a push southwards of cold air into that region and some sort of moisture would bring that snow."

Kids enjoyed the freak snowfall, making snowmen and sledding down sand dunes, while adults had to deal with their vehicles getting stranded on icy roads, according to Forbes. By the day's end, temperatures climbed to 42°F and sand dunes returned to their ordinary brown—just long enough for residents of Aïn Séfra to experience both the highs and lows of an ordinary snow day.

How Waffle House Helps Measure the Severity of a Natural Disaster

There are a lot of ways the Federal Emergency Management Agency (FEMA) assesses and addresses the severity of a natural disaster. Meteorology can predict movement patterns, wind gusts, and precipitation. Resources are dispatched to areas hit hardest by torrential weather.

But when the agency needs an accurate, ground-level gauge for how a community is coping during a crisis, they turn to Waffle House.

Since 2004, FEMA has utilized what former administrator Craig Fugate called the “Waffle House Index.” Because the casual dining chain is open 24 hours a day, seven days a week, tracking to see if a location is closed or working with limited supplies can help inform the agency as to whether affected areas are ailing or taking steps toward normalcy.

“If a Waffle House is closed because there's a disaster, it's bad,” Fugate told NPR in 2011. “We call it red. If they're open but have a limited menu, that's yellow ... If they're green, we're good, keep going. You haven't found the bad stuff yet.”

For FEMA, the ability to order a plate of smothered and covered hash browns is an important analytic. If a Waffle House is having trouble getting stock, then transportation has been interrupted. If the menu is limited, then it’s possible they have some utilities but not others. If its locations have locked their doors, inclement weather has taken over. The chain’s locations would normally stay open even in severe conditions to help first responders.

The company has opened a Waffle House Storm Center to gather data in anticipation of Hurricane Florence, a Category 2 storm expected to touch down in the Carolinas this week. But not all locations are taking a wait-and-see approach. One Waffle House in Myrtle Beach, South Carolina has already closed due to the looming threat, making it the first red dot on the Index.

See What Hurricane Florence Looks Like From Space

As Hurricane Florence continues to creep its way toward the Carolinas, it’s repeatedly being described as both "the storm of the century” and "the storm of a lifetime” for parts of the coastlines of North and South Carolina. While that may sound like hyperbole to some, Alexander Gerst—an astronaut with the European Space Agency—took to Twitter to prove otherwise with a few amazing photos, and issued a warning to “Watch out, America!”

According to the National Weather Service, “Hurricane Florence will be approaching the Carolina shores as the day progresses on Thursday. Although the exact timing, location, and eventual track of Florence isn't known, local impacts will likely begin in the afternoon hours and only worsen with time throughout the evening and overnight period.”

On Tuesday, Wilmington, North Carolina's National Weather Service took the warning even one step further, writing: "This will likely be the storm of a lifetime for portions of the Carolina coast, and that's saying a lot given the impacts we've seen from Hurricanes Diana, Hugo, Fran, Bonnie, Floyd, and Matthew. I can't emphasize enough the potential for unbelievable damage from wind, storm surge, and inland flooding with this storm.”

Gerst’s photos certainly drive that point home.
