Mrs.M, the power problem is due to fallen and damaged utility poles and lines, mostly due to high wind and too much snow on trees and branches (causing trees and branches to crash down, often into homes, cars, power lines and roads). This storm was particularly destructive to certain areas because the leaves were still on the trees. Several inches of snow on leaved-trees made for too much weight, and down came the trees. Because the ground was already saturated, many trees just uprooted themselves and feel over... even 200 year-old oaks. There seemed no logic to it; many, many "strong" trees, both young and old, just split in half. Farther up North, the storm was not a problem because the leaves were already off the trees for the season.
That makes sense - of course there aren't usually leaves on trees during a snow storm!
