Nashville, TN – Three words in a winter weather warning could signal a storm far more dangerous than the snow and ice Tennessee residents typically experience. During the 2026 27 winter season, those words could carry an urgent message from Nashville and Memphis to Knoxville, Chattanooga and mountain communities.
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 critical infrastructure.
What Are the Three Words Tennessee Residents Should Know?
"Particularly Dangerous Situation" highlights an extraordinary threat within an existing winter weather warning.
A Blizzard Warning indicates strong winds and severely reduced visibility from falling or blowing snow. Adding PDS wording would emphasize unusually dangerous conditions.
In an Ice Storm Warning, the wording could highlight extreme threats from damaging ice accumulation.
Why Could This Matter Across Tennessee?
Tennessee faces several winter hazards, with freezing rain posing a particular concern across much of the state.
Memphis, Jackson and western Tennessee can experience damaging ice storms, while Nashville, Murfreesboro and Clarksville face risks from snow, sleet and freezing rain.
Knoxville, Johnson City and the higher elevations of the Appalachian Mountains can experience significant snowfall and dangerous mountain travel.
During an extreme event, Interstate 40 between Memphis, Nashville and Knoxville, Interstate 65 through Middle Tennessee and Interstate 75 near Chattanooga and Knoxville could experience serious disruptions.
Heavy ice accumulation can bring down trees and power lines, potentially leaving homes without electricity or reliable heating.
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 Tennessee winter storms will not receive the designation.
What Should Tennessee 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 Tennessee.
