Catalina/Santa Barbara Islands, Malibu, Los Angeles County Beaches and Ventura County Beaches were placed under a coastal flood advisory by the National Weather Service on Saturday at 8:10 p.m. The advisory is in effect until Tuesday Sept. 8, at 11 p.m.
“Moderate coastal flooding expected,” according to the NWS Los Angeles/Oxnard CA. “High tides will occur around 6.7 feet at 6pm on Sunday, 7 feet at 7pm on Monday, and 7.2 feet at 8pm on Tuesday.”
“There is an increased risk for ocean drowning. Rip currents will be widespread and very strong, potentially pulling swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. Enhanced beach erosion will occur. Flooding of sea water is likely, around the time of high tide, over vulnerable low-lying coastal areas such as parking lots, beaches, and walkways. Areas most susceptible to coastal flooding will include Avalon, Long Beach (Alamitos Peninsula), and Oxnard to Malibu (including Point Mugu),” the NWS said. “Remain out of the water due to dangerous surf conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks. Follow advice from local officials. Do NOT drive around barricades or through water of unknown depth.”
Deciphering advisories, watches, and warnings: Understanding weather alerts
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 doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
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 reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.
Adhere to 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 allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.
Avoid basements and submerged areas:
Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
Swift evacuation for your safety:
If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.
Refrain from walking in 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 higher ground when 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 potential for flooding, particularly in areas that are low-lying or prone to floods. It is crucial to never drive through water on the road, even if it appears shallow. According to the NWS, as little as 12 inches of fast-flowing water can carry away most vehicles. Stay safe by being prepared and informed.
