Mill Valley Issues Flood Advisory for High Tides, Warning of Traffic Congestion
The City of Mill Valley has issued a flood advisory for November 4-9, 2026, due to higher-than-normal high tides forecasted by the National Weather Service. Tides are expected to be up to 1.2 feet above astronomical tides, with peak tides reaching 7.4 feet on Saturday, November 7, Sunday, November 8, and Monday, November 9. This weather event is anticipated to cause flooding on low-lying roads and shoreline areas, leading to temporary road or lane closures, ponding near storm drains, and water in low-lying parking areas. Specific areas likely to be affected include Miller Avenue between Camino Alto and Almonte, the 500 block of Redwood Highway Frontage Road, and the Manzanita 101 freeway access. Residents are advised to plan for slower drainage and increased traffic congestion, particularly during morning commute hours. The city recommends moving vehicles from low-lying parking spots and protecting flood-prone properties.
