On Monday at 1:37 p.m. the National Weather Service issued a coastal flood advisory in effect until Wednesday June 17, at 2 a.m. for Los Angeles County Beaches.
“Minor, but impactful coastal flooding expected,” according to the NWS Los Angeles/Oxnard CA. “Coastal flooding concerns will peak from from around 8 p.m. through midnight Monday night and Tuesday night, due to high astronomical tides of 7.2 ft to 7.7 ft.”
“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. Significant damage to roads or structures is NOT expected. The highest risk for coastal flooding will be near low-lying areas of Long Beach. There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore,” the NWS said. “Take the necessary actions to protect flood-prone property. Do NOT drive around barricades or through water of unknown depth. Remain out of the water due to hazardous swimming conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks.”
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 doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
Keeping safe during floods: Expert advice from the NWS
In flood-prone regions or while camping in low-lying areas, understanding and following the NWS flood safety guidelines can be a lifesaver:
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.
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 allows, disconnect your utilities and appliances. This reduces the risk of 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 noises, evacuate immediately. Avoid any water that may be charged with electricity.
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. Prioritize your safety by staying informed and prepared.
