The Mount Holly, NJ office of the Weather Service said issued a Winter Weather Advisory for a large area that includes northern Delaware.
Again, the I-95 corridor is the area of greatest uncertainty when it comes to the type of precipitation.
As of Monday, temperatures were above freezing, a contrast to weekend ice accumulations on vehicles, driveways, and some roads.
A wintry mix could come down between Monday afternoon and early Tuesday morning.
Though accumulations from the latest storm will be light, any amount of freezing rain can cause difficult travel conditions, especially on untreated and elevated roads, the weather office cautioned.
DelDOT crews plan to put salt down on primary roads. Still, freezing rain is more difficult to treat than snow. Examples of primary roads across the state are I-95, Route 1, Route 9, Route 13, Route 26, Route 113, and Route 404.
According to a DelDOT release, freezing rain dilutes the effectiveness of salt faster than snow and can cause the road surface to rapidly freeze.
Untreated secondary and local roads will likely be icy and caution is advised for anyone who must travel. Black ice can form instantly and create hazardous driving conditions.
