Redding, Calif. – Thunderstorms are set to return to Northern California through Wednesday, bringing heavy rain, flooding risks, and slick travel across Shasta County, the Sierra Nevada, Coast Range, and southern Cascades. Some of the strongest storms could cause flash flooding in low-lying areas and across roadways.
According to the National Weather Service in Sacramento, storm chances range from 20% to 40% across the region, with Shasta County facing the highest risk. Thunderstorms that do form will likely produce heavy rainfall, increasing the potential for ponding water and dangerous driving conditions.
Communities including Redding, Chico, and Susanville could see repeated downpours through Tuesday night, with storm activity stretching into the Sierra passes. Drivers are urged not to attempt crossing flooded roadways, as even shallow water can be life-threatening. Caltrans warned of slick roads on Interstate 5 near Redding and Highway 44 into Lassen County during peak storm periods.
Rainfall rates could overwhelm storm drains in city centers, while rural foothill areas may face washouts and debris flows. Residents are encouraged to keep phones charged in case of power outages and allow extra travel time when storms are nearby.
The storm threat will linger until Wednesday morning, with additional watches and advisories possible if conditions worsen.
