HIDE Special Weather Statement issued January 17 at 6:07PM EST by NWS Greenville-Spartanburg
...AREAS OF BLACK ICE EXPECTED TO CAUSE TREACHEROUS ROAD
CONDITIONS OVERNIGHT AND TUESDAY MORNING...
Abundant sunshine in most areas allowed roads to warm and driving
conditions to improve for a time Monday afternoon. However, in
most areas where snow is on the ground, they remained wet from
snowmelt. Tonight will be considerably colder than Sunday night,
and any roads that were still wet at sunset likely will freeze
over. Black ice will be a significant road hazard overnight
through at least late Tuesday morning, when sunshine should again
allow the ice to thaw.
Transportation agencies have advised the public to stay off the
roads unless absolutely necessary. Any motorists that do venture
out are urged to use extreme caution. If a road looks wet, it
likely is covered in a thin sheet of ice.
