El Niño's intensified weather patterns pose risks of flooding, especially during king tides. Coastal areas in San Diego County, including Mission Beach and Harbor Drive, have already seen minor flooding. The combination of high tides and strong storms could lead to more severe damage in the coming months. Additionally, marine heat waves are exacerbating tidal heights, increasing the likelihood of coastal inundation. Residents in flood-prone areas should remain vigilant as El Niño strengthens.
