Coastal Flood Advisory

* WHAT...Minor to moderate coastal flooding expected due to very high tides.

* WHERE...Catalina and Santa Barbara Islands.

* WHEN...Until 1 PM PDT Thursday.

* IMPACTS...Minor to moderate flooding of sea water is likely over vulnerable low-lying coastal areas, especially around the time of high tide, including over beach parking lots, bike paths, and harbor walkways. Moderate to significant beach erosion is likely. Isolated damage of structures due to sea water inundation is possible to the most vulnerable areas.

* ADDITIONAL DETAILS...High tides will likely reach 7.5-8.0 feet (MLLW) each late morning, which is 1.0 to 1.5 feet above astronomical projections. The highest tides will be Monday through Wednesday. There is a small chance for isolated Coastal Flood Warnings Wednesday through Thursday if larger surf develops. The Coastal Flood Advisory may also need to be extended beyond Thursday.
