Details
* WHAT...For the High Surf Warning, dangerously large breaking waves along the coast. For the Coastal Flood Advisory, minor coastal flooding. Inundation of 1.75 to 2.25 feet above ground level is possible along shorelines and low-lying coastal areas.
* WHERE...Grays Harbor County Coast zone.
* WHEN...For the High Surf Warning, until noon PST Saturday. For the Coastal Flood Advisory, until 5 PM PST this afternoon.
* IMPACTS...Minor coastal flooding due to tidal overflow is expected around high tide. This may lead to flooding of parking lots, parks, and roads, with only isolated road closures expected. Dangerous breaking waves can knock people off their feet and sweep them into the ocean. Driftwood and debris in powerful surf can injure or even kill people on the beach observing the ocean. High surf will result in erosion to beaches, dunes, and bluffs and may cause damage to roads, trails, and coastal structures.
* ADDITIONAL DETAILS...Significant log and debris pile-up on the beaches and jetties from the high surf last weekend will pose additional threats to those on the beaches and will exacerbate coastal erosion.
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.
Inundation above ground level refers to the height above the Mean Higher High Water (MHHW) level.
Everyone should remain out of the water and well back from the surf zone. This includes staying off jetties, piers, and other coastal structures. Never turn your back on the ocean and keep children and pets close. Know the tides and forecast conditions. Follow warning signs and respect barriers.
