California Coast Weather Alert: Up to 3 Inches of Rain Possible Through Wednesday

EUREKA, CALIFORNIA – A slow-moving storm system is forecast to bring several inches of rain to Northern California from late Sunday through Wednesday morning, raising concerns about localized flooding and runoff.

Heavy Rainfall Expected

According to the National Weather Service in Eureka, rainfall totals will depend on the storm’s track, but between 1 and 3 inches are possible over a 72-hour period. Forecasters estimate a 75% chance that most areas will see at least an inch of rain, with a 25% chance totals could exceed 2 inches, based on storm modeling projections.

The heaviest rain is expected along the coast and in higher terrain across Humboldt, Del Norte, and Trinity counties, where runoff into rivers and streams could trigger minor flooding.

Travel and Safety Impacts

Officials warn that travel may be slowed on U.S. Highway 101 and rural roads, where water can quickly pool. Residents are advised to clear storm drains, secure outdoor items, and monitor river levels closely.

Communities from Crescent City to Eureka should prepare for periods of heavy downpours, especially on Monday and Tuesday, when rainfall intensity is forecast to peak.

Midweek Outlook

The system is expected to weaken by Wednesday, with showers tapering off. However, forecasters caution that if the storm strengthens, additional advisories could be issued.

Northern California’s first major storm of September is a reminder of the region’s vulnerability to heavy rain events, especially in coastal and mountainous areas. For more weather updates and community alerts, follow ChicagoMusicGuide.com.
