California wakes to steady rain tapping rooftops along the North Coast, with gray skies pressing low over Humboldt Bay. Pavement shines, gutters run full, and umbrellas struggle against the persistent drizzle.
A prolonged period of heavy rain is developing across Eureka and coastal Humboldt County, with multiple rounds expected through Friday, December 19. National Weather Service data shows rain chances near 100 percent Thursday and Friday, with 1 to 2 inches possible, especially during heavier bands.
Morning temperatures stay mild near the upper 40s to mid-50s. That warmth keeps precipitation as rain, but it also allows runoff to build quickly. Poor drainage areas, small streams, and coastal roadways may see ponding water by late Thursday.
Travel impacts increase as rain intensifies. Drivers along US-101, local surface streets, and rural highways should expect slick pavement and reduced visibility. Hydroplaning becomes a concern during heavier downpours, particularly after dark.
Winds remain modest overall, but gusts near passing showers could reach 20 to 25 mph, enough to push water across roadways and drop small debris. Outdoor plans may need adjustment as steady rain limits visibility and comfort.
By Friday, rainfall peaks again. Showers turn heavier at times, and standing water may linger into the evening commute. While flooding is not widespread, localized issues can develop quickly, especially near creeks and low-lying neighborhoods.
Looking ahead to the Christmas travel weekend, the weather remains unsettled. Rain likely continues into Saturday, though intensity gradually eases. For now, colder air stays north, keeping snow out of Eureka. Still, meteorologists flag this pattern as an early winter signal, with more active systems lining up offshore.
What to do now:
Slow down on wet roads. Avoid standing water. Allow extra time for travel.
