Eureka, CA – Rain returns within the next 24 hours across northwest California, with a multi-day system set to bring up to 3.00 inches of rainfall in higher terrain and renewed flooding concerns through midweek.
According to the National Weather Service in Eureka, a slow-moving frontal system will push into the region Sunday evening, with the heaviest and most persistent rainfall expected Monday through Tuesday. Valley locations, including Eureka, Arcata, and Crescent City, are projected to receive between 0.50 and 1.00 inch of rain, while coastal mountains could see 1.50 to 3.00 inches.
Road conditions may deteriorate quickly, especially along U.S. Highway 101 and State Route 299, where reduced visibility and slick pavement could impact travel. Small streams and creeks may rise rapidly, and low-lying or poor drainage areas could see minor flooding as rainfall continues over multiple days.
Localized rockslides remain possible in steep terrain, particularly in Del Norte and Humboldt counties. Residents should secure outdoor items, avoid driving through flooded roadways, and monitor water levels near creeks.
Rain is expected to taper into scattered showers by Wednesday, with drier conditions likely returning late in the week. Additional advisories may be issued as rainfall totals increase.
