LOUISVILLE, Ky. (WDRB) -- The National Weather Service is now convinced Sunday's weather will be a significant event and they expect a quarter to a half an inch of ice. 

WDRB meteorologist Jeremy Kappell says this could be the most impactful weather event we have had this season. "After an eventful winter, this will be the icing on the cake" Kappell says. 

You can follow Jeremy Kappell's updates, along with the rest of the weather team, on the WDRB Weather Blog. We will bring you the latest updates on WDRB.com and on WDRB News @ 10 Saturday night and WDRB in the Mornings on Sunday morning starting at 6 AM. 

Louisville/Jefferson County Metro Emergency Management spokesperson Jody Duncan spoke with WDRB and other stations on a conference call Saturday afternoon. Duncan outlined the expectations for Sunday's weather and what the city is doing to prepare for it. 

The NWS has issued a winter storm warning from 10 AM Sunday until 1 PM Monday. With the ice and snow accumulations expected, Duncan said with trees and electric lines weak from previous winter weather, "we could have power outages that could last from 12-24 hours."

Louisville Metro EMA and LG&E will open their emergency operations center with a level one activation Sunday. The Red Cross will be on stand by.

If and when salt is needed, officials with Public Works say they have enough. New Albany Officials say they are mixing IMIX with what little salt they have left. IMIX is sand treated with calcium chloride, a chemical that reacts to water and generates heat.

Duncan reminds residents to never put generators inside in case of power outages.
