California is preparing for a series of storm systems that will bring significant rainfall, hazardous driving conditions, and an increased risk of mudslides, particularly in fire-affected areas. The Pacific Coast Highway has closed again just one day after reopening due to concerns of flooding and mudslides. Rain is expected to start on Tuesday and last through the week, with two separate storms set to impact the Central Coast and Los Angeles County. Local authorities are taking precautions to protect vulnerable regions, ensuring that communities prepare for the possible dangers that accompany heavy rain, including debris flows and flash flooding. While the rainfall could provide some relief from ongoing fire threats, it may not be sufficient to end fire season completely.
