Drivers are urged to exercise caution during their morning commutes as black ice may have reformed in isolated spots on Houston roadways overnight. Drivers should look for any wet surfaces, as they can be icy.

What is black ice? Temperatures may have warmed up but some Houston-areas are still experiencing freezing temperatures which can cause a very thin layer of ice to accumulate on pavements.

Although temperatures are rising across the Houston area after two days of snow and ice, officials are still urging motorists to exercise caution on the roads.
