Vigo County was downgraded Tuesday to a travel watch, along with Parke and Vermillion Counties.
Sullivan County will also switch to a level 2 watch Wednesday at 6 a.m. All their county and city offices will re-open Wednseday.
What do all these different levels of travel advisories mean?
The lowest level is a travel advisory. This means that routine travel or activities might be restricted in areas because of a hazardous situation, and you should use caution.
The next level is a travel watch, where only essential travel, like to and from work or in emergency situations, is recommended.
The highest level is a travel warning; this is where roads are closed except for emergencies.
