Columbia, SC – Three words in a winter weather warning could signal a storm far more dangerous than the snow and ice South Carolina residents typically experience. During the 2026 27 winter season, those words could carry an urgent message from Columbia and Greenville to Charleston, Myrtle Beach and communities across the Upstate.
According to NOAA's Weather Prediction Center, the National Weather Service is expanding the use of "Particularly Dangerous Situation," or PDS, wording in select Blizzard Warnings and Ice Storm Warnings this winter.
The wording is intended for rare, exceptionally dangerous storms that could threaten lives, transportation and essential infrastructure.
What Are the Three Words South Carolina Residents Should Know?
"Particularly Dangerous Situation" signals an extraordinary threat beyond the hazards already described in a winter weather warning.
A Blizzard Warning indicates dangerous winds and severely reduced visibility from falling or blowing snow. PDS wording would emphasize an unusually severe threat.
In an Ice Storm Warning, the wording could highlight extreme risks from damaging ice accumulation.
Why Could This Matter Across South Carolina?
South Carolina's winter weather risks vary considerably by region.
Greenville, Spartanburg and other Upstate communities can experience snow and freezing rain, while Columbia and the Midlands face potentially disruptive ice storms.
Charleston, Myrtle Beach and coastal communities experience winter precipitation less frequently, but freezing rain and icy roads can still create serious hazards.
During an extreme event, Interstate 26 between Columbia and Charleston, Interstate 85 through the Upstate and Interstate 95 across eastern South Carolina could become hazardous.
Heavy ice accumulation can bring down trees and power lines, potentially leaving homes without electricity or heat.
These are possible impacts, not predictions of an approaching storm.
Is PDS a New Winter Weather Warning?
No. PDS is additional wording within certain existing Blizzard Warnings and Ice Storm Warnings, not a separate warning category.
Most winter storms will not receive the designation.
What Should South Carolina Residents Do?
If PDS wording appears, residents should avoid unnecessary travel, follow emergency instructions and prepare for potentially prolonged disruptions.
The expanded terminology does not mean a catastrophic winter storm is currently forecast for South Carolina.
