The rain that preceded overnight snowfall in the early morning hours of Sunday washed away some road crew preparations, road managers report.

Pennsylvania Department of Transportation crews observed rainfall until about 1:30 a.m., according to Brent Piccola, assistant maintenance manager for the county. By the time rain gave way to snow, he said, much of their road treatments were being washed away.

"As hard as it was coming down last night, we couldn't apply much chemical or treatment to the roads," Piccola said.

That isn't to say they didn't try: PennDOT road crews hit the streets to prepare for the storm at about 3:00 a.m. Saturday, Piccola said. Crews were working 12-hour shifts.

On Sunday morning, they had 40 trucks out clearing Butler County roads, he said.

"No one is going home until the roads are safe," Piccola said.
