Trio of storms bring potential for widespread river flooding, gusty winds Scott Sistek | KOMONews.com Meteorologist Replay Video UP NEXT SEATTLE -- A trio of soggy storm systems are poised to race through the Pacific Northwest over the next four days bringing heavy rains and periods of gusty winds, with enough rainfall in the mountains for potential river flooding. The first storm will roll in Friday, with a second, stronger storm due in later Saturday into Sunday. A third storm completes the rainy hat trick on Monday. The winds will be rather "old hat" for typical late autumn storms but the rains could be heavy enough to trigger widespread flooding on rivers in the Cascade and Olympic Mountains.
