On Wednesday at 11:39 a.m. a coastal flood advisory was issued by the National Weather Service in effect until Friday Oct. 30, at 2 p.m. for Catalina/Santa Barbara Islands.
“Minor to moderate coastal flooding expected due to very high tides,” the NWS Los Angeles/Oxnard CA said. “High tides will likely reach 7.5-8.0 feet (MLLW) late morning Thursday, which is 1.0 to 1.5 feet above astronomical projections. Decreasing some on Friday but still expecting near 7.5 feet (MLLW) around noon.”
“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,” according to the NWS. “Take the necessary actions to protect flood-prone property. Do NOT drive around barricades or through water of unknown depth.”
Understanding the differences between advisories, watches, and warnings
Flash flood warning: Take action.
A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
Flood warning: Take action.
A flood warning is issued when flooding is imminent or occurring.
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.
Staying safe during a flood: Recommendations from the NWS
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:
Move to 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.
Adhere to evacuation orders:
When local authorities issue an evacuation order, promptly comply. Before 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:
Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
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 high ground if trapped:
Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the NWS, as little as 12 inches of rushing water can sweep away most vehicles. Stay safe by being prepared and informed.
