When it comes to weather, it's hard to sound scarier than "bomb cyclone."

It's a version of a real weather term that applies to a massive winter storm that pulled together Wednesday off the U.S. Southeast coast. But as fearsome as the storm is with high winds and some snow, it may not be quite as explosive as the term sounds.

Meteorologists have used the term "bomb" for storms for decades, based on a strict definition, said University of Oklahoma meteorology professor Jason Furtado.

After it showed it showed up in a Washington Post story on Tuesday, the weather geek term took on a life of its own on . The same thing happened four years ago with "polar vortex," another long-used weather term that was little known to the public until then.

"Bombogenesis is the technical term. Bomb is a shortened version of it, better for social media," said Weather.US meteorologist Ryan Maue, who helped popularize polar vortex in 2014.

"The actual impacts aren't going to be a bomb at all," Maue said. "There's nothing exploding or detonating."

Storm intensity is measured by central pressure—the lower the pressure, the stronger. A storm is considered a "bomb" when the pressure drops rapidly—at least 24 millibars in 24 hours.

This storm looks like it will intensify at twice that rate, said Bob Oravec, lead forecaster at the National Weather Service's Weather Prediction Center.

So far, the storm has dumped freak snow on the Southeast. It's aiming for the Northeast, where the snow forecast for Thursday isn't that big a deal, Furtado and others said. The worst of this will stay out to sea. What is going to be bigger is the high winds—gusts exceeding 60 mph—and the bitter cold that follows, they said.

Bomb cyclones draw air from polar regions after they leave. In this case, it means extra cold Arctic air because of where the is, Furtado said.

Worldwide, about 40 to 50 "bomb cyclones" brew each year, but most are over open ocean and nobody but geeks notice, Maue said.

"We use the term bomb," Furtado said. "We know what it means, but I do think it gets a little hyped up."
