SYNOPSIS:
- High clouds are moving north as a weak low-pressure system off Southern California spreads light rain across Northwest California Wednesday night through Thursday night.
- Rainfall totals from this first system will be moderate (0.5–1.5 inches, locally up to 2 inches), with minimal flooding or wind concerns.
- A brief dry window (6–12 hours) is possible Friday morning before the next, stronger storm arrives.
- The second system Friday–Friday night will bring heavy rain (0.5–3 inches) and strong southerly winds, especially across coastal ridges and headlands from Humboldt northward.
- Continued moisture flow through the weekend may keep rain and wind impacts going, with increasing flood potential into early next week if the moisture plume remains stalled over Northern California.
COASTAL FLOOD WATCH REMAINS IN EFFECT FROM THURSDAY MORNING THROUGH SATURDAY AFTERNOON
