Experts Warn Winter Storm Fern Could Be “Catastrophic” — These 12 Cities Are in the Crosshairs

What Makes Fern So Dangerous (It’s Not Just Snow)

People hear “winter storm” and picture snowfall totals.

That’s only part of it.

The bigger risk, in many places, is a layered mess of snow, sleet, and freezing rain — and the rapid temperature swings that lock it all into place.

That mix can turn roads into glass, bring down branches and power lines, and trap people at home with no heat.

Forecasters often worry about a few things in storms like this:

  • Ice accumulation: even a thin glaze can shut down highways and snap tree limbs.
  • Power outages: ice + wind + heavy branches can trigger outages that last longer than people expect.
  • Temperature drops: the colder it gets after the precipitation, the longer the damage “sticks.”
  • Travel paralysis: airports, interstates, and city roads can gridlock at the same time.

And there’s one more problem nobody wants to hear:

Even after the storm “ends,” conditions often stay dangerous for days because temperatures remain below freezing.

So yes, the storm is the headline.

But the aftermath is where people get stuck.
