Storm total snow accumulations Downeast ranged from 12 to 18 inches...with 10 to 16 inches across central areas and 9 to 13 inches across extreme northern areas. Heavy wet snow accumulating on trees snapped branches and weighed down other branches to the point where they contacted power lines. The heavy snow also brought down some power lines. The most extensive power outages occurred across central and Downeast areas where nearly 6000 customers lost power for varying amounts of time. Power outages were also reported across northern areas...though in much lower numbers.
