Indiana Department of Homeland Security officials have issued a travel advisory for Tippecanoe County because of increasing snow cover on local roads.
An "advisory" is the lowest of three levels of concern the state uses. It means anyone on the roads should use caution. As of midday Sunday, several Indiana counties had advanced to the "watch" level, which means that nonessential travel should be curtailed.
No Indiana counties have yet been put on the highest, or "warning," level of alert, which makes it illegal for any non-emergency personnel to be on the roads because of hazardous conditions.
