The advisory is in effect from 6 a.m. to 12 p.m. PST on Wednesday, with forecasters warning that seawater could inundate 1.75 to 2.25 feet above ground level in low-lying coastal and shoreline areas. It could result in 'minor flooding,' NWS said.

The NWS said the flooding will be driven by tidal overflow around the morning high tide. It could lead to water covering parking lots, parks, and roads, particularly near shorelines, NWS said, adding that road closures are also possible.
