Yellow Flag

This is the yellow flag at the beach, when it's green the water is really calm and you can swim way out in the ocean, when it's yellow not so far (knee level) or you can get taken by the under tow of the waves. When it's RED you must not go in at all! When my sister and brother inlaw went down in January they were very intoxicated and went in on a red flag and got whistled out!!! LOL
