Black Ice Will Result in Continued Treacherous Roadways!!!
• Watch out for dangerous black ice on the roadways across North and Central Georgia!
• Partial melting yesterday with re-freezing overnight has created a very dangerous situation.
• Afternoon temps will warm above freezing but lingering ice is still possible • Anything left by
evening will re-freeze
• Situation similar to 2011 with stretches of dry roadway followed quickly by ice covered stretches.
Travel is strongly discouraged on
roadways !
