Details
* WHAT...For the Coastal Flood Advisory, minor coastal flooding expected. Inundation of 1.5 to 2 feet above ground level is possible along shorelines and low-lying coastal areas. For the High Surf Advisory, large breaking waves along the coast.
* WHERE...Northern Washington Coast and Grays Harbor County Coast zones.
* WHEN...For the Coastal Flood Advisory, from 10 AM this morning to 3 PM PST this afternoon. For the High Surf Advisory, from 10 AM this morning to 10 AM PST Wednesday.
* 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. Large breaking waves can knock people off their feet, move driftwood and debris, and crash over rocks and jetties. People can be injured or drown while observing the ocean. Localized beach and coastal erosion is expected.
* 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.
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.
