Acton, CA Warnings, Watches and Advisories

Coastal Flood Advisory issued November 9 at 7:41AM PST until November 10 at 12:00PM PST by NWS Los Angeles/Oxnard CA

* WHAT...For the Coastal Flood Advisory, moderate coastal flooding expected. For the High Surf Advisory, large breaking waves of 10 to 16 feet with dangerous rip currents. * WHERE...San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches. * WHEN...Until noon PST Tuesday. * 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 near 7.0 ft (MLLW) are expected each morning. The High Surf and Coastal Flood Advisories may need to be extended through the week.

Beach Hazards Statement issued November 9 at 7:41AM PST until November 10 at 12:00PM PST by NWS Los Angeles/Oxnard CA

* WHAT...Dangerous rip currents and breaking waves due to elevated surf up to 4 to 6 feet expected. Minor tidal overflow possible during morning high tides, especially across west facing beaches. * WHERE...Santa Barbara County Southwestern Coast and Santa Barbara County Southeastern Coast. * WHEN...Through Tuesday morning. * IMPACTS...There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. Pooling of sea water is possible around high tide at beach and harbor areas that is uncommon with normal tidal ranges. Enhanced beach erosion is also possible. * ADDITIONAL DETAILS...High tides of 7.2 to 7.4 feet (MLLW) are expected each morning.

High Surf Advisory issued November 9 at 7:41AM PST until November 10 at 12:00PM PST by NWS Los Angeles/Oxnard CA

For the High Surf Advisory, dangerous rip currents and large breaking waves of 5 to 7 feet, except peaking at 6 to 9 feet on Monday. * WHERE...Ventura County Beaches. * WHEN...Until noon PST Tuesday. * IMPACTS...There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. Flooded sandy beach areas and moderate beach erosion possible. Localized and shallow flooding of beach parking lots, bike paths, and walkways. Isolated damage is unlikely, but cannot be discounted. * ADDITIONAL DETAILS...High tides of 7.0 to 7.3 feet (MLLW) are expected each morning. Surf and coastal flooding impacts peak on Monday. Additonal products will likely be needed through the week.

Coastal Flood Advisory issued November 9 at 7:41AM PST until November 10 at 12:00PM PST by NWS Los Angeles/Oxnard CA

* WHAT...Minor to locally moderate coastal flooding during morning high tides, as well as dangerous rip currents and breaking waves due to elevated surf up to 4 to 6 feet expected, especially across west facing beaches. * WHERE...Catalina and Santa Barbara Islands, Malibu Coast and Los Angeles County Beaches. * WHEN...Until noon PST Tuesday. * IMPACTS...There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. Pooling of sea water is possible around high tide at beach and harbor areas that is uncommon with normal tidal ranges. Enhanced beach erosion is also possible. * ADDITIONAL DETAILS...High tides of 7.2 to 7.4 feet (MLLW) are expected each morning. Surf and coastal flooding impacts peak on Monday. Since the large swell is from the west, south facing areas such as Malibu and Long Beach will be less affected unlike the previous events where the swell was from the south.

Coastal Flood Advisory issued November 9 at 5:28AM PST until November 9 at 12:00PM PST by NWS Eureka CA

* WHAT...High astronomical tides will cause minor flooding in low lying areas around Humboldt Bay. Up to one half foot of saltwater inundation above ground level is possible near shorelines and tidal waterways. Between 8.7 and 9.0 feet MLLW at the North Spit tide gauge is predicted. * WHERE...Northern Coastal Humboldt County. * WHEN...From 10 AM to noon PST Monday. High tide is at 10:52 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.

Beach Hazards Statement issued November 9 at 5:06AM PST until November 10 at 10:00PM PST by NWS San Diego CA

* WHAT...Minor to locally moderate coastal flooding expected. Additionally, dangerous rip currents and surf of 3 to 7 feet expected along west-facing beaches. * WHERE...San Diego County Coastal Areas. * WHEN...For the Coastal Flood Advisory, until noon PST Tuesday. For the Beach Hazards Statement, through Tuesday evening. * IMPACTS...Flooding of parking lots and roads with only isolated road closures expected. Dangerous swimming conditions due to elevated surf and strong rip currents. * ADDITIONAL DETAILS...Highest tides will occur in the morning each day, peaking at 7.2-7.4 feet today, which is 1.2 to 1.4 feet above astronomical tide predictions. Higher surf today could prolong coastal impacts.

Coastal Flood Advisory issued November 8 at 7:50PM PST until November 13 at 4:00PM PST by NWS San Francisco CA

* 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. For the Beach Hazards Statement, through 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: 1.5 ft above normal (7.3 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, 1.3 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.

Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location. This is done to help with preparing for severe weather that may overlap or be heading towards Acton.
