The first winter storm of the season has left North Texas, but cold temperatures have frozen the water and slush that remained on the ground. TxDOT and cities have been working to clear ice from the roads, but there are still dangerous road conditions.

Tony Hartzel, a Dallas district spokesperson for the Texas Department of Transportation, said the roads in the Dallas area are still fairly passable – but that there could be hotspots.

Black ice is a thin layer that forms on surfaces such as roads, sidewalks and driveways when temperatures are 30 degrees or lower.

This week's North Texas snow event will end with a few flurries during Friday's morning commute, leading to hazardous road conditions.

North Texas is experiencing a mix of snow and sleet​, causing road closures and traffic delays across the Metroplex.
