One of the main impacts was the ever-increasing high tides. These were forecast to be this year’s king tides -- the highest high tides of the year. The reasoning is that during certain astronomical configurations of the Earth, Moon and Sun can add to tidal ranges. King high tides run about 6″-12″ higher than normal astronomical tides. Interestingly, low tides also run below their normal range, by about 6″-12.″ The result is for a far greater range from low to high tides.
Relaxing onshore wind will also allow for outgoing tides to “flush” back into the Atlantic Ocean. If you live along any inland tidal river, or creek, do expect decreasing threats of backyard flooding.
Atlantic Ocean high tides were higher than normal and reached the sand dunes with each high tide (there are two each day).
So far, we have seen moderate high tide flooding at Mayport and through areas of St. Johns County.
