Some schools delay opening for black ice

Granville County, Person County, Caswell County and Alamance-Burlington schools were among the school systems that delayed opening by two hours.

A spokesperson for Granville County schools said that there was a lot of black ice on roads in the northern part of the county.

Low temperatures and early Thursday overnight froze standing water leftover on roads from a rainy Wednesday. Temperatures were in the low 20s and upper 30s shortly after dawn Thursday.

"We've got ice out there. It's not widespread, but patches could be anywhere in our viewing area, because temperatures are hovering around freezing," said WRAL traffic reporter Brian Shrader.

"Slow down, and anticipate what's happening around you. If it looks wet, just assume it's ice."
