  outcomes follow a ‘bell curve’ (normal) distribution symmetrical around the best estimate. In practice, the distribution may be multi-modal rather than normal. For this reason, forecasts were made for the probability that the number of storms will lie in pre-defined ranges, or categories (e.g. 10

Typically, water is 10 times as dense as snow so multiplying by 10 gives an approximate depth of the snow, although wet snow can be significantly denser and powder snow much less dense.
