COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 2 PM PDT TUESDAY... ...HIGH SURF ADVISORY REMAINS IN EFFECT FROM 6 AM TO 10 PM PDT SUNDAY

For Ventura County Beaches, from Los Angeles/Oxnard, CA

What

For the Coastal Flood Advisory, minor to moderate coastal flooding can be expected near times of high tide, especially with the Sunday morning high tide. Localized damage is possible in most vulnerable low-lying areas. For the High Surf Advisory, large breaking waves of 5 to 8 feet with dangerous rip currents is expected on Sunday.

Where

Ventura County Beaches.

When

For the Coastal Flood Advisory, until 2 PM PDT Tuesday. For the High Surf Advisory, from 6 AM to 10 PM PDT Sunday.

Impacts

Sea-water flooding of beach and harbor roads, parking lots, and walkways is likely, especially around the time of high tide. Isolated damage is possible during the Sunday morning high tide which is expected to peak around 8 feet. The most vulnerable locations to coastal flooding will be low-lying areas from Ventura to LA county line. Localized pockets of Highway 1 between Point Mugu and LA county line could see significant surf spray and some sea-water on the roadway. Significant beach erosion is expected. 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 approaching 8 feet will be likely on Sunday morning (nearly 2 feet above astronomical high tide of 6.1 feet), returning to around 7.5 feet for Monday and Tuesday mornings. Large secondary high tides are also expected each evening.

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.

For Malibu Coast; Los Angeles County Beaches, from Los Angeles/Oxnard, CA

What

DAMAGING sea-water coastal flooding is likely through Sunday, especially near the Sunday morning high tide where anticipated tide levels are expected to be around 8 feet. The most likely areas for DAMAGING coastal flooding on Sunday morning will be vulnerable south-facing beaches due to the expected combination of very high level tide levels around 8 feet (including additive effect of low barometric pressure and onshore winds gusting to 15 to 25 mph), high surf of 5 to 8 feet, and light to moderate rainfall. For all other beaches, minor to moderate coastal flooding is expected near times of high tide. From Sunday night through Tuesday, there will be the continued threat of at least minor to moderate coastal flooding and elevated surf across Los Angeles county beaches, especially south facing shores. Dangerous rip currents are likely.

Where

Malibu Coast and Los Angeles County Beaches.

When

For the Coastal Flood Warning, until 3 PM PDT Sunday. For the High Surf Advisory, from 6 AM to 10 PM PDT Sunday. For the Coastal Flood Advisory, from 3 PM Sunday to 2 PM PDT Tuesday.

Impacts

For vulnerable south-facing beaches (such as Alamitos Peninsula and Naples in Long Beach as well as Malibu), SIGNIFICANT sea- water flooding will likely DAMAGE coastal structures and beach roadways around the time of high tide, especially the Sunday morning high tide. In addition, significant ponding of water on low-lying beach roadways could make driving difficult. THERE IS GROWING CONFIDENCE THAT THE EXPECTED COASTAL FLOODING IMPACTS ON SUNDAY MORNING FOR VULNERABLE SOUTH FACING BEACHES OF LA COUNTY COULD BE THE MOST SIGNIFICANT WE HAVE SEEN SO FAR THIS SEASON, INCLUDING THOSE SEEN WITH MARIE. For all other beaches and harbors, shallow with minor to moderate sea- water flooding will likely impact beaches and walkways, especially with the Sunday morning high tide which could cause local damage to most vulnerable locations such as Venice. For all beach areas, significant erosion is expected. There is an increased risk for ocean drowning. Dangerous and life- threatening 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 around 8 feet are expected on Sunday morning (nearly 2 feet above astronomical high tide of 6.1 feet), returning to around 7.5 feet for Monday and Tuesday mornings. The projected high tides of around 8 feet for Sunday morning would approach or exceed recent record tide levels for LA county. Large secondary high tides are also expected each evening.

What to do

Follow directions of emergency officials. Stay off of beaches and coastal walkways, roads, and structures. 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.

For San Luis Obispo County Beaches; Santa Barbara County Central Coast Beaches, from Los Angeles/Oxnard, CA

What

For the Beach Hazards Statement, Minor tidal overflow flooding and strong rip currents are expected. For the Coastal Flood Advisory, minor to moderate coastal flooding can be expected near times of high tide, especially with the Sunday morning high tide. For the High Surf Advisory, large breaking waves of 8 to 12 feet is expected with dangerous rip currents.

Where

San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches.

When

For the Beach Hazards Statement, through late tonight. For the Coastal Flood Advisory, from 6 AM Sunday to 10 PM PDT Monday. For the High Surf Advisory, from 6 AM Sunday to 10 PM PDT Monday.

Impacts

Minor to moderate flooding of sea water is likely around high tide at beach and harbor areas that is uncommon with normal tidal ranges. Low lying areas will be most susceptible, including Oceano. Enhanced beach erosion is likely. The risk for significant damage is very low. 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. Large secondary high tides are also expected each evening.

Additional details

High tides are expected to peak around 7.5 feet on Sunday morning, then around 7 feet on Monday 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.
