Overview
- Localized minor flooding inundated streets and neighborhoods in Marin County early Monday, prompting road closures and advisories to avoid affected areas.
- The National Weather Service issued a coastal flood advisory that forecasts tidal anomalies of about 1.2 to 2.0 feet above normal through Thursday with peak times near midnight in San Francisco on Tuesday and Wednesday.
- Long-period southerly swell has elevated the risk of sneaker waves and strong rip currents on south- and southwest-facing beaches, and the NWS urged beachgoers to use caution through Thursday.
- Local agencies opened sandbag distribution points in Mill Valley and warned residents to use alternate routes and avoid low-lying roads and parking lots that may flood.
- Meteorologists note this event fits a pattern of rising Bay water levels and say a strong El Niño could make similar high-tide flooding and larger coastal waves more frequent in coming months.
