Description

What

For the Beach Hazards Statement, dangerous rip currents and breaking waves due to elevated surf. For the Coastal Flood Advisory, moderate coastal flooding expected. For the High Surf Advisory, breaking waves of 4 to 7 feet with dangerous rip currents.

Where

Catalina and Santa Barbara Islands, Ventura County Beaches, Malibu Coast and Los Angeles County Beaches. Focused across exposed south facing coasts.

When

For the Beach Hazards Statement, through 5 AM Monday. For the Coastal Flood Advisory and High Surf Advisory, from 5 AM Monday to 5 PM PDT 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 to locally significant beach erosion is likely. Very localized damage possible to most vulnerable areas. 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

Areas of most concern are Avalon, Long Beach (Peninsula and Belmont Shore). While the surf will likely be smaller than Marie (from earlier this month), the lingering erosion effects enhances the vulnerabilities for locally more significant coastal flooding.

Instructions

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. Remain out of the water due to hazardous swimming conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks.
