Low-lying roads and parking structures in areas like Fashion Valley Mall became submerged, and emergency services performed multiple water rescues. Notable incidents included the rescue of an adult and a child from a submerged vehicle at Fashion Valley, and a dramatic rescue near Lake Hodges where a woman was swept into a creek.
