The second of three winter storms wreaked havoc Saturday through San Diego County, causing flooding, downed trees and power outages. In Del Mar, there were reports of a bluff collapse on the train tracks. Train passengers were ferried between the Solana Beach and Sorrento Valley stations while train services were stopped. A track inspector said it was ice plants falling into the ocean and not the bluff. On the main street in Del Mar, there was flooding. A crew from the swift water rescue told NBC 7 it was on standby in case anyone got stuck in the water.
