The Metrolink Orange County Line suspension between Laguna Niguel/Mission Viejo and Oceanside ended as scheduled after Aug. 14, with no extension reported. According to Metrolink's Upcoming Advisories page, the OC Line suspension is listed only for Aug. 10–14; the next listed closures concern the Antelope Valley Line. The NWS San Diego Coastal Flood Advisory expired after 11 PM PDT Aug. 12 and has not been reissued. NOAA data shows the Aug. 15 Newport Beach forecast peak falling to 5.2 ft — a marked decline from the 6.6–6.9 ft peaks recorded at the cycle's height. A High Tide Alert was still logged at Newport Beach in the early hours of Aug. 15, but tidal activity is now easing toward background levels consistent with the close of this astronomical cycle.

The advisory window documented minor coastal flooding during evening high tides each night, with peaks ranging from 6.6 ft (Aug. 9) to 6.9 ft (Aug. 10 and Aug. 12) and advisory projections reaching 7.2–7.5 ft. NWS identified impacts including inundation of low-lying parking lots, parks, and roadways along the OC coast. The Aug. 13 king tide forecast of 6.5 ft and the subsequent Aug. 14 forecast of 5.9 ft confirmed a steady decline from peak levels, consistent with the astronomical alignment weakening. No structural damage or injuries have been reported in available evidence.

Metrolink suspended Orange County Line service south of Laguna Niguel/Mission Viejo beginning Aug. 10, citing forecast high-tide risk to the coastal rail corridor. Trains originated and terminated at Laguna Niguel/Mission Viejo for the duration; no bus bridge was provided. Amtrak's Pacific Surfliner, which shares the LOSSAN corridor, logged extended delays on both Aug. 13 and into the early hours of Aug. 14, consistent with ongoing disruptions on the affected segment. The suspension lifted after Aug. 14 with no extension.

Separate from the tidal suspension, OCTA added roughly 1,000 tons of riprap near Cyprus Shore and south San Clemente in recent weeks as precautionary emergency work after hurricane swell moved rock onto the tracks. OCTA indicated it would seek a retroactive emergency Coastal Commission permit covering work since June, with a hearing targeted for the September commission meeting. San Clemente officials have asked the Coastal Commission to allow the city to lead sand replenishment rather than continued rock placement. Community meetings on the Coastal Rail Resiliency Study were held Aug. 10–11, reflecting broader, longer-term concerns about the corridor's vulnerability independent of this tidal event.

The formal NWS advisory has closed, tidal levels are receding, and the Metrolink suspension has lifted on schedule. This astronomical tidal cycle is effectively over. The situation is expected to move to resolved status absent any new advisories or reported impacts.
