The National Weather Service in Gray has issued a winter weather advisory until 7 p.m.

“Low pressure will track across southern New England and near the Maine coast this morning,” the agency said early Tuesday morning. “This low has spread snow and mixed precipitation across the area much of New Hampshire and western Maine. This mixed precipitation will make for slippery travel in many areas today.”
