NWS Bay Area's Sunday discussion turns sea-level arithmetic into sidewalk advice. The key messages are minor coastal flooding across low-lying coastal areas, hazardous beach conditions through Tuesday, sneaker waves, strong rip currents, and minor to locally moderate HeatRisk through midweek. [1]
The paper's June 13 brief on flash flooding as summer health planning argued that weather receipts matter when they change where people drive, walk, store belongings, and check local alerts. The Bay Area version is tidal: high-tide coastal flooding will continue nightly along low-lying Bayshore and Pacific Coast areas through midweek. [1]
The math is unusually plain. NWS says tides may rise up to 2.0 feet above normal, driven by Sunday's new moon and lunar perigee, about 7 inches of tidal anomaly from storm surge and thermal expansion in the eastern Pacific, and about 2 inches of sea-level rise since vertical datums were established in the 1980s and 1990s.

Weather.gov is the front door for local forecasts, warnings, river products, marine products, and safety information when those numbers become a trip or beach decision. [2]
The argument is not whether the tide proves a worldview. It is whether low sidewalks, bayshore parking, beach paths, and rip currents change tonight's behavior. Sea-level math is already standing in the street.
