Food and water aren't the only things people are looking to lock down ahead of this week's big nor'easter.

More than one-third (31%) of singles ages 18-24 have sought out casual sex during a winter storm, according to a recent survey by Trojan Condoms.

The data shows that 70% of people looking for a snowstorm hookup will attempt to contact an old flame who may be interested in getting snowed in together. Meanwhile, nearly half (49%) would look for someone on a dating app like Tinder to spend the snowy day with. (Need help optimizing your Tinder profile? We've got you covered.)

Millions Are Feeling the Nor'easter Chill

According to CNN, more than 50 million people stretching from Maryland to Maine are under at least a winter storm watch today, while nearly 2,000 flights have already been canceled. This could mean a lot of people are about to get busy.

It's a well-known anecdote that winter storms produce so-called "baby bumps." In other words, people tend to get it on during blizzards — and then get pregnant. (Makes sense, given that Trojan's survey found that nearly half of people don't stock up on condoms during a storm.)

"With low-level, low-severity storm advisories, we actually found an uptick in births nine months later," Richard Evans, a professor of economics at Brigham Young University, told NPR in 2016. He said the baby bumps tend to happen around storms like this one — they're not life-threatening, but they're just annoying enough to make you stay inside all day.

"If the lights go out and there's no TV, it kind of sets the table for romance, and you get births nine months later," he said.
