On Friday at 2:18 p.m. the National Weather Service issued a coastal flood warning in effect until Sunday Oct. 11, at 3 p.m. for Catalina/Santa Barbara Islands.
“For vulnerable south-facing beaches, like Avalon and Pebbly Beach, damaging sea-water flooding is likely. For all other beaches and harbors, minor coastal flooding is expected,” can be anticipated according to the NWS Los Angeles/Oxnard CA. “Sunday carries the widest range of coastal flooding outcomes due to chances of rain, wind, low pressure tidal enhancements, and swells from multiple directions. Coastal flooding impacts on Sunday could be similar to other days, or greatly enhanced. High tides of 7.3 to 7.6 feet will be common each morning. This warning may be extended past Sunday, or converted to a Coastal Flood Advisory through Tuesday.”
“For vulnerable south-facing beaches, sea-water flooding can damage beach roads and structures, especially around the time of high tide. For all other beaches and harbors, shallow and minor sea-water flooding can impact beaches and walkways. For all beach areas, significant erosion is expected. There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea,” the NWS said. “Stay off of beaches and coastal walkways, roads, and structures. Do NOT drive around barricades or through water of unknown depth. Heed advice from local officials.”

Where to get sandbags
If you’re in an area at risk of flooding, sandbags can be one line of defense. County fire departments typically offer a limited supply of free sandbags for residents of their nearby communities. You should bring your own shovel to fill your bags, and be prepared to show proof of residency.
Sand and sandbags can also be purchased at many home improvement and hardware stores.

Your guide to weather alerts: 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 released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that 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.
Keeping safe during floods: Expert advice 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.
Follow 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 allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.
Avoid 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 if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.
Seek high ground if 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 heavy rainfall, especially in low-lying and flood-prone areas, the risk of flooding escalates. Remember this crucial advice: never attempt to drive through water on the road, even if it appears shallow. According to the NWS, as little as 12 inches of rapidly flowing water can carry away most vehicles. Stay safe by being prepared and informed.
