Orange County Coast and San Diego County Coastal Areas are under a coastal flood advisory which was issued by the National Weather Service on Thursday at 1:32 p.m. The advisory is valid from Saturday 6 a.m. until Tuesday Sept. 8, at 11 p.m.

“Large breaking waves of 6 to 10 feet for south and southwestern-facing beaches and 4 to 7 feet for west-facing beaches. Strong and dangerous rip and longshore currents. Minor coastal flooding from a combination of high surf and high astronomical tides,” can be expected according to the NWS San Diego CA. “Predicted tides for La Jolla, CA: Sat, Sep 5 2026: 6.0 feet at 4:48 p.m. Sun, Sep 6 2026: 6.3 feet at 6:03 p.m. Mon, Sep 7 2026: 6.7 feet at 7:03 p.m. Tue, Sep 8 2026: 6.8 feet at 7:54 p.m.”

“Flooding of lots, parks, and roads with only isolated road closures expected. Dangerous swimming and surfing conditions and beach erosion,” according to the NWS. “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. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Always swim near a lifeguard. Stay off of sea walls and jetties. Waves will occasionally run farther up the beach than expected, especially during high and rising tides; set up farther back from the ocean and do not turn your back on the ocean.”


Understanding the differences between advisories, watches, and warnings

Flash flood warning: Take action.

A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.

Flood warning: Take action.

A flood warning is declared when flooding is on the verge of happening or is already underway.

Flood advisory: Be aware.

A flood advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.

Flood watch: Be prepared.

A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.

When floods strike: Guidelines from the NWS for your protection

Floods can pose a significant threat, especially if you live in a flood-prone area or find yourself camping in a low-lying region. To ensure your safety, the NWS offers essential flood safety guidelines:

Seek higher ground:

If you’re in a flood-prone area, or if you’re camping in a low-lying spot, move to higher ground as a first step.

Follow evacuation orders:

If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

Disconnect utilities and appliances:

If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.

Steer clear of flooded basements and submerged areas:

Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.

Evacuate promptly for safety:

If you notice sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate without delay. Do not enter water that may carry an electrical charge.

Stay away from floodwaters:

Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.

Seek higher ground when trapped:

In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911.

During periods of intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it seems shallow. According to the NWS, most cars can be swept away by just 12 inches of rushing water. Stay safe by being prepared and informed.
