The heavy rainfall poses a significant risk of flooding in streets, creeks, and rivers, particularly in areas with recent wildfire burn scars. The Bryson Fire burn scar near Malibu is of particular concern, as these areas are prone to landslides and rapid water runoff. Communities in the Santa Monica Mountains and surrounding areas should prepare for potential disruptions, including road closures and localized flooding. Thunderstorms and hail could also create hazardous conditions for outdoor activities and travel.
