WHAT. For the Coastal Flood Advisory, up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. For the Beach Hazards Statement, an increased risk for sneaker waves and strong rip currents with breaking waves of 12 to 16 ft expected.
WHERE. Southern Monterey Bay and Big Sur Coast.
WHEN. For the Coastal Flood Advisory, until 4 PM PST Friday November 13. For the Beach Hazards Statement, until Monday evening.
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. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks.
ADDITIONAL DETAILS. At the San Francisco tide gauge, high tide is expected to be: 1.6 ft above normal (7.4 ft MLLW) at 9:38 AM Saturday 11/7, 1.6 ft above normal (7.4 ft MLLW) at 10:06 AM Sunday 11/8, 1.6 ft above normal (7.4 ft MLLW) at 10:35 AM Monday 11/9, 1.5 ft above normal (7.3 ft MLLW) at 11:04 AM Tuesday 11/10, 1.4 ft above normal (7.2 ft MLLW) at 11:35 AM Wednesday 11/11, 1.4 ft above normal (7.2 ft MLLW) at 12:10 PM Thursday 11/12, 1.2 ft above normal (7.0 ft MLLW) at 12:49 PM Friday 11/13. These predictions include up to 1.5 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.
What to do.
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.
Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. Monitor local weather, surf and tide forecasts at www.weather.gov/mtr.

What to do.
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.
Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. Monitor local weather, surf and tide forecasts at www.weather.gov/mtr.

IMPACTS. Moderate flooding of sea water is likely over some vulnerable low-lying coastal areas, especially around the time of high tide, including over beach parking lots, bike paths, and harbor walkways. Moderate beach erosion is likely. Isolated damage is unlikely but possible. There is an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore.
ADDITIONAL DETAILS. High tides of 7.1 to 7.4 feet (MLLW) are expected each morning.
What to do.
Take the necessary actions to protect flood-prone property. Do NOT drive around barricades or through water of unknown depth.
Remain out of the water due to dangerous surf conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks.
WHAT. For the Coastal Flood Advisory, High astronomical tides will cause minor flooding in low lying areas around Humboldt Bay. Up to one quarter foot of saltwater inundation above ground level is possible near shorelines and tidal waterways. Between 8.8 and 9.0 feet MLLW at the North Spit tide gauge is predicted. For the High Surf Advisory, large breaking waves 22 to 24 feet.
WHERE. Northern Coastal Humboldt County.
WHEN. For the Coastal Flood Advisory, from 9 AM to 11 AM PST this morning. For the High Surf Advisory, from 4 AM to 10 PM PST Sunday. High tide is at 9:51 AM at the Humboldt Bay North Spit tide gauge. Saltwater inundation will be possible 1 to 2 hours before and after high tide.
IMPACTS. Flooding of low lying areas around Humboldt Bay including parks and roads with only isolated closures expected. Flooding will likely impact Jackson Ranch Road in the Arcata Bottoms and several roads in King Salmon. Dangerous surf conditions and localized beach erosion. Beachcombing is highly discouraged!.
ADDITIONAL DETAILS. The large surf on Sunday will coincide with high astronomical tides and high tidal anomalies. This will allow significant runup onto area beaches and may impact normally dry land or even roads or parking lots.
What to do.
A Coastal Flood Advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore.
Feet Above Ground is locally defined as feet above the Highest Astronomical Tide or HAT.
Large breaking waves along the coast will lead to increased wave run-up on beaches with waves topping and washing over large rocks and jetties. These large waves can be erratic and unpredictable. Use extra caution near the surf zone as these large waves will be capable of sweeping people into the frigid and turbulent ocean water. Mariners traversing the bar are urged to exercise extreme caution or stay in port until the threat subsides. Please contact the U.S. Coast Guard for information regarding harbor and bar closures.
National Weather Service river gauges reporting flooding now, or forecast to flood. “Near flood stage” is the NWS action stage: the level where someone has to start doing something.
Flash flood warning: flash flooding is happening or about to, usually from intense rain over a few hours. Move to higher ground; never drive into water over the road.
Flood warning: flooding is happening or imminent, often a river rising over a day or more.
Flood watch / flash flood watch: conditions could produce flooding; it hasn’t started.
Flood advisory: minor flooding that’s a nuisance (low roads, poor drainage) rather than a threat to homes.
Coastal flood warning / advisory: tides or wind pushing seawater onto land, often at high tide.
Storm surge warning: life-threatening rise of seawater moving inland from a tropical storm or hurricane.
Is your address in the flood zone? Search it above for FEMA’s zone and base flood elevation. A new flood insurance policy usually takes 30 days to start (NFIP rule; exceptions include a policy bought when closing a mortgage), so one bought during a flood generally won’t cover it. Homeowners policies don’t cover flood.
