Description

What

Up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways.

Where

Coastal North Bay Including Point Reyes National Seashore, San Francisco Peninsula Coast and Northern Monterey Bay.

When

Until noon PST today.

Impacts

High tides will result in flooding of low-lying infrastructure, isolated road closures, and coastal erosion. Rising tides will bring water and waves farther up the beach than normal, restricting escape from beaches and coastal areas.

Additional details

At the San Francisco tide gauge, high tide is expected to be: 1.4 ft above normal (7.2 ft MLLW) at 11:35 AM Wednesday 11/11, 1.3 ft above normal (7.1 ft MLLW) at 12:10 PM Thursday 11/12, 1.1 ft above normal (6.9 ft MLLW) at 12:49 PM Friday 11/13. These predictions include up to 1.4 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.

Instructions

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.
