This has been a winter of extremes. In early winter the three-week period of cold temperatures drove the frost deep into the ground. A full thaw usually happens in mid to late March, but the deep frost may extend the amount of time it takes for the rain and snow-melt water to drain away.
Recently we have had rain and snow that melted quickly due to above normal temperatures, creating a bathtub of mud on top of the frozen dirt roads. Until the frost goes out of the road, allowing them to drain, driving on dirt roads will be the next challenge provided by nature.
Your highway department personnel will be doing their best to make the roads as safe as possible under these weather conditions.
