Already, the “deep and fast moving storm” has dumped between two to seven inches of rain over elements of western Oregon, Washington, and California between Monday and Wednesday morning. In Portland, the rainfall flooded roadways. And, coupled with excessive winds, the storm knocked out energy for greater than 100,000 households—greater than 60,000 of which are nonetheless with out electrical energy, as of writing.
