I was 8b now 9a according to the new maps even though the most recent few years have proven to be 8b not 9a. My area got down to 16 degrees in January this year and in the teens the previous year as well. I don't know what prompted the change but none of the new areas they moved into 9a are 9a. The lowest temperatures were 3 to 5 degrees warmer on average 10 to 20 years ago than they are now.
