Road conditions overall are not that bad. Went to Nyack an back. Worst part is River Road particularly In Edgewater. I would recommend the group going out tomorrow (sunday) to stay single file all the way to the GWB. On River Rd there are some parts with no shoulder at all and with one of the lanes partially blocked.
Going out was not an issue since there arent many cars at that time but be careful coming back. May be better to take the road that runs parallel to river Rd up to the Japanese supermarket. As you are coming down the GWB just make a right after the River palm restaurant (there’s a fire station on the corner). Go up a short hill and follow that road until you see the supermarket and golf driving range.
Stay warm and safe out there.
