The National Weather Service issued a coastal flood advisory for Clatsop County Coast at 7:56 p.m. on Sunday. The advisory is in effect for Tuesday from 8 a.m. to 2 p.m.
According to the weather service, “Minor tidal overflow flooding expected.”
Low-lying locations close to bays, sloughs, and the lower reaches of coastal rivers are susceptible to minor tidal overflow flooding during high tides, up to 0.5 feet above ground level. Destructive waves may wash over beaches, jetties, and other structures unexpectedly. While watching heavy surf, people can get washed off rocks and jetties and drown. Buildings and properties along the seaside may sustain minor beach erosion. The weather agency notes, “Beaches are predicted to have higher than usual water run-up. “Tidal overflow flooding is anticipated when there is a coastal flood advisory in effect. Residents living along the coast in the region under warning should be on the lookout for rising water and take the necessary precautions to save lives and property.

When floods strike: Guidelines from the weather service for your protection
Knowing and adhering to the weather service’s flood safety recommendations can be extremely helpful when camping in low-lying areas or in places that are prone to flooding:
Look for higher ground.
Moving to higher ground is the first line of defense if you live in an area that floods easily or are camping in a low-lying area.
Respect evacuation directives:
Immediately comply with any evacuation orders issued by local authorities. Make sure your house is locked before you leave.
Cut off appliances and utilities:
Disconnect your appliances and utilities if you have the time. By taking this precaution, electrical dangers during flooding are reduced.
Steer clear of waterlogged regions and basements:
Stay away from rooms with electrical outlets or cords that are submerged in water or basements. Electrical accident prevention is essential.
Quickly leave for your safety:
Evacuate right away if you see sparks or hear popping, crackling, snapping, or buzzing noises. Avoid going into water that might be electrically charged.
Avoid the floodwaters:
Even if floodwaters seem shallow, you should never try to go over them. You can be swept off your feet with power by just 6 inches of swift-moving water.
When stuck, look for higher ground:
If you find yourself caught by flowing water, move to the highest spot you can and dial 911 to reach rescue personnel.
Flooding is a possibility during periods of high rainfall, particularly in low-lying and flood-prone locations. Never drive on water on the road, even if it appears to be shallow. The weather service claims that most cars can be washed away by as little as 12 inches of swiftly moving water. Put your safety first by being aware and ready.
