State highway officials say road conditions, which had improved from salting at mid-day are once again treacherous due to refreezing. Crews remain out in force in Crittenden and surrounding counties, said Keith Todd, spokesman for the Kentucky Department of Highways.
"Drifts have been a problem throughout the day. Wind has continued to blow snow across road surfaces. That has prompted most counties to start plowing in an effort to knock down drifts," Todd said.
As temperatures drop through the night, driving conditions are likely to deteriorate even further, Todd added.
Once temperatures drop below about 18 degrees, salt and other ice-fighting chemicals lose their effectiveness, the said.
"As drivers prepare for the morning commute, highway officials are asking everyone to allow extra driving time and use appropriate caution," said Todd. "Due to the temperatures down in the teens overnight some slick spots are going to remain. The cold temperatures can also cause re-freezing overnight creating an additional hazard on the morning commute."
The US Weather Service has issued a Winter Weather Advisory for all of Kentucky.
