The weekend storm's force had not reached Devore by late Friday afternoon. But already, a rolling fog had reached the area, giving drivers and residents a clue about what might be on the way.
"Ice on the roads," David Easley predicted. "The roads become slick. The winds pick up and turn some vehicles over."
Over at the Summit Inn in Oak Hill, they were seeing the sunny side of the expected weather mayhem. Waitress Joanie Blackburn said she was looking forward to the storm.

"I always do," Blackburn said. "I love it. Because we get more business here."
Blackburn is used to seeing the highway in front of her restaurant. Sometimes the 215 shuts down because of snow. The locals say it can get ugly and you have to be prepared.
"Four wheel drive trucks are the best way," said Jerry Thurbush, of Oak Hill.
The California Highway Patrol was still hoping late Friday that I-15 would stay open overnight. But it all depended on the timing and intensity of the storm.
"If you are planning on driving Cajon Pass, you want to have supplies in your vehicle and possibly know alternate routes just in case we do have to shut things down," said CHP Officer Daniel Hesser.
With the snow level possibly dropping to 3,000 feet, CHP officers stressed that drivers use caution.
"Southern California drivers, we don't slow down," Hesser said. "That's the other thing we are not necessarily used to during adverse weather, as people are in other states."
Thurbush says he has a good plan in place.
"Just don't go nowhere," Thurbrush said.
