Weather authorities are maintaining a coastal flood advisory this Wednesday, August 12, due to elevated tides expected tonight in low-lying areas near the shoreline.

The National Weather Service (NWS) in San Diego has issued a Coastal Flood Advisory through 11 p.m. for coastal areas of San Diego and Orange counties. The agency expects minor flooding associated with tonight’s high tides.

The NWS forecasts tides ranging from 6.9 to 7.2 feet between 9 and 10 p.m., with the highest tide expected at approximately 9:30 p.m.

The elevated tides could cause temporary water accumulation in beach parking lots, boardwalks and some roads located in low-lying areas. The risk is mainly associated with the high tide, while wave conditions are not expected to significantly increase the potential for flooding during this event.

The NWS recommends that people traveling through coastal areas tonight allow extra time for their trips, as some roads could experience temporary impacts or closures.

Authorities also advise drivers not to go around barricades or attempt to drive through water of unknown depth, as conditions can change quickly and pose a danger to motorists.

Although the flooding is expected to be minor, it could temporarily affect traffic and access to areas located along the shoreline.

The advisory coincides with a day of moderate temperatures and mostly cloudy skies in San Diego. The forecast calls for a high near 80 degrees Fahrenheit (27 °C) and a low around 68 °F (20 °C) overnight.

At 6:20 p.m., San Diego International Airport was reporting 73 °F (23 °C), mostly cloudy skies and 73 percent humidity.

The advisory does not mean that all of San Diego is at risk of flooding. Potential impacts are concentrated mainly in low-lying coastal areas during the high-tide period.

Residents, workers and visitors near the beaches tonight are encouraged to monitor weather updates and avoid parking or spending unnecessary time in areas that could be affected by rising water.

The period requiring the most caution will be between 9 and 10 p.m., when the highest tide is expected. The advisory will remain in effect through 11 p.m. Wednesday.
