Welcome Storm 58!
Storm 58 is a old, expanding and dying wave headed to the west coast from deep in the Pacific. Within its wide circumference, new jet stream energy is creating a storm for Sunday. So, Saturday belongs to a minor storm that basically just washes ashore. And Sunday is the REAL next storm event.
It has made landfall in the Pacific Northwest, where Seattle is 8 inches ahead of its wettest year on record. For this blog,, however, landfalls in the PNW do not count. Landfall in California is the start time of a new storm, and, as usual, Crescent City is the first to register rainfall from this Pacific Northwest storm. Storm 57 is leaving California and the Pacific NW via Idaho, Nevada and Arizona.
