Special Weather Statement issued January 23 at 4:49PM CST by NWS Mobile AL

Re-freezing of snow melt is expected again overnight, as
temperatures plummet into the 20’s. This will create areas of
slippery black ice, especially in places that have not already
completely dried out or in places that have remained shaded
through the day. This includes roadways that remain shaded by
trees or by overpasses or anyplace on the shaded north side of
buildings.

If you must be out tonight, be ready for the sudden re-freezing
of puddled water from snow melt, resulting in the formation of
black ice. Slushy snow will become icy and hard. If driving, slow
way down before encountering icy spots. Allow extra space between
you and surrounding vehicles. If walking on foot, avoid icy spots
if you can.
