According to Chris Isdell at the Accomack County VDOT, all roads on the Eastern Shore are "passable", i.e. they are not closed.
Route 13 is now 95% cleared. Primary roads have been 50% cleared by VDOT and secondary roads, which include back roads and necks, have been 15% cleared.
Temperatures will drop back down into the teens tonight and any wet roadways will refreeze, which is likely to re-create hazardous roadways Thursday morning. Isdell said VDOT crews will be out in force Wednesday evening to try and keep the roads clear.
Isdell said he was hopeful that temperatures would increase Thursday enough to help melt the snow on the road. However, temperatures are only forecast to be in the low 30s for a high Thursday, the low 20s for a high Friday, and will finally rise into the 40s on Saturday.
