Sacramento, California – Rainfall across Northern California tapered Wednesday morning, leaving slick road conditions on major commuter routes including Interstate 5, Interstate 80, and U.S. Highway 50.
According to the National Weather Service Sacramento office, the heaviest 24-hour rainfall totals were recorded in Shasta County and adjacent upper foothill areas, where several locations measured more than half an inch of rain as of 4 a.m. PST Wednesday. Redding reported approximately 0.52 inches, while surrounding foothill zones saw similar accumulations.
Farther south, lighter totals were observed across the Sacramento Valley. Downtown Sacramento measured roughly 0.25 inches, while Stockton and parts of San Joaquin County recorded closer to 0.10 inches. Despite lower totals, wet pavement conditions persisted during the early morning commute.
Transportation corridors including I-5 through Sacramento and Redding, I-80 east of Sacramento, US-50 toward El Dorado County, and CA-99 near Stockton experienced reduced traction during peak travel hours. Officials urged drivers to allow extra stopping distance and remain alert for lingering slick spots, particularly on on-ramps, overpasses, and shaded roadway segments.
The National Weather Service noted that rainfall intensity diminished overnight, with no additional significant accumulation expected later Wednesday. However, residual moisture may continue to impact traffic during the morning commute window.
Young workers, students, and early-morning commuters were among those most affected, as wet roadways coincided with school and work travel periods across the region.
No flood advisories or warnings were issued with this system, and rivers and streams remained within normal levels as of Wednesday morning. Weather conditions are expected to gradually improve as cloud cover breaks later in the day.
