The NWS San Diego Coastal Flood Advisory for Orange County Coastal Areas remains active through 11 PM PDT Wednesday, Aug. 12. Minor coastal flooding is expected during evening high tides each night, with peaks of approximately 7.2–7.5 ft occurring between 7:30 and 10 PM. Metrolink's Orange County Line suspension between Laguna Niguel/Mission Viejo and Oceanside remains in effect through Aug. 14.

NWS forecasts impacts including inundation of low-lying parking lots, parks, and roadways along the OC coast. NOAA tide gauge data recorded a king tide forecast of 6.9 ft at 20:04 on Aug. 10, consistent with advisory projections. A high tide alert was also logged at Newport Beach in the early hours of Aug. 10. The prior evening (Aug. 9) saw a king tide forecast of 6.6 ft at 19:11, confirming the pattern of elevated tidal cycles across the advisory window.

Metrolink suspended Orange County Line service south of Laguna Niguel/Mission Viejo station beginning Aug. 10. The suspension covers the segment to Oceanside and is scheduled to remain in place through Aug. 14. The action was taken preemptively due to forecast high tides posing a risk to the coastal rail corridor. Riders requiring travel south of Laguna Niguel are advised to consult Metrolink's service page for alternate transit options.

The advisory window closes after the evening high-tide cycle on Aug. 12, but the Metrolink suspension continues through Aug. 14, suggesting rail operators are maintaining caution beyond the formal advisory period. No structural damage or injuries have been reported in available evidence. Conditions should be monitored each evening during the 7:30–10 PM peak window through the end of the advisory.
