The storms are expected to bring significant rainfall, particularly to Northern California, which could see up to six inches of rain. While the risk of flooding is predicted to be low, the heavy rain may lead to slippery roads, increasing the likelihood of traffic disruptions and accidents. Coastal areas could face hazardous conditions due to waves reaching up to 50 feet, posing risks to marine activities and shoreline infrastructure. The storms are also expected to bring strong winds, which could cause localized power outages and minor property damage.
