“There remains some uncertainty for the exact location and timing of the freezing rain axis, as well as the amount of ice accretion that may occur,” the watch said. “Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.”
The national weather agency said that freezing rain warnings are expected to be issued as the event draws nearer.
