Marin County Airport - Gnoss Field, California

* WHAT...Up to 1.2 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...Bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay. * WHEN...Now through 5 PM PDT Thursday. * IMPACTS...Flooding of lots, parks, and roads with only isolated road closures expected. High tides will result in flooding along coastal trails, cut off access to some low- lying beaches and coastal areas, and bring water and waves farther up the beach than typical. * ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide is expected to be 1.2 ft above normal (7.03 ft MLLW) at 2:10 PM Wednesday 9/30, and 1.1 ft above normal (6.92 ft MLLW) at 2:58 PM Thursday 10/01. These predictions include up to 0.7 ft of surge that will enhance the astronomical tide and flooding threat. High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively. If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.
