Ice dam risk in East Providence, RI
Ice dams in East Providence, RI: how often
6.0 dam days a winter
Moderate risk. On an ordinary house in East Providence, conditions for an ice dam come on about 6.0 days in a normal winter, mostly in January and February.
East Providence averages 37 inches of snow a year and about 25 days with snow on the ground. Plenty falls, but it tends to melt off between storms, which keeps the count lower than the snowfall suggests. That gap is why snowfall alone misleads.

Where these numbers come from
