I had the same problem, I was originally scheduled take to exam in NH on 3 /7 in the morning, drove all the way there to find out they were closed and the snow did not even start yet??? Called to reschedule now need to drive to Mass to take on 3/21 which is the first available one, as others stated cancelled again, although snow still has still not started yet. After 2 hours on the phone last night with Prometric, I am now scheduled to take it on Friday 3/23 in NYC. So now I have a 4.5 hour drive, hotel stay, parking..... Completely crazy how quickly they close sites for the day although add no additional testing days. I will be glad when this is finally over..
