Always watch where you are, and don't get trapped with an incoming tide or wave, where there is a steep bank that may trap you. There are logs rolling in the water that are very difficult to see. Sneaker waves can appear very quickly. Never turn your back to the ocean. Please do not stand or walk, or especially let children play on logs on the beach or in the water.
Water can roll a log, even a huge log, very easily and quickly.
Each year many people are rescued, and some killed from rolling logs. A small child can be crushed under a log, and drown. It does not take much water to move a log. Sneaker waves can appear at any time, and you can't run fast when in water. Even on dry sand, you never know when a sneaker wave will appear.
