(Cincinnati) --Heavy snowfall made the Tuesday morning commute slow and messy in the tri-state. Hundreds of schools delayed classes or cancelled after several inches of snow blanketed area roads.

Jared Bolden with Cincinnati Public Services, says City Crews hit the street at 11:00 P.M. Monday night pretreating the roads with salt. Over 130 snow plows and salt trucks were out trying to keep up with the snow that Bolden said started to really come down at 3 A.M. Two inches of snow were reportedly already on the ground when the National Weather Service issued a Winter Weather Advisory.

Temperatures during the morning commute were in the teens helping the snow stick to roads becoming icy, especially on highway overpasses and entrance and exit ramps. Several minor accidents and slide offs were reported around the tri-state that temporarily closed interstates or slowed traffic down to a 20 to 30 mph crawl.

Commuters were urged to take extra time to get to work and to not follow too closely. Around 10 A.M. Bolden said the warming temperature helped the streets start responding to the treatment.

Level 1 Snow emergencies were issued Tuesday morning in Butler, Hamilton, Clinton, and Grant Counties.

Of the hundreds of schools that closed Cincinnati Public Schools stayed open for class and the University of Cincinnati remained open for their finals week.

Some flight delays were also reported in the state, the snow storm was expected to move southeast through the day.

Jared Bolden says roads should be clear for the drive home saying "we'll work throughout the day on into the evening to make sure it’s done, so we won’t stop until its complete." and that he hopes "to have a nice smooth commute home this evening."
