“Extreme high tides, or “king tides”, occur at a few specific times during the year when the moon is closest to the Earth. During these high water events, we can see what the average water levels might look like in the future, given projected sea level rise.” from The King Tides Project
Since the sea level has risen about 9 inches since the turn of the last century this is adding to this phenomenon. We are seeing flooding in certain areas unrelated to rain events, simply because of these high tides.
October 8th is the King Tide for the fall.
The King Tides Project invites people to visit the shoreline and capture images of important places threatened by sea level rise. If you take pictures of the king tide near you, please upload them to assist scientists in understanding better how sea level rise will affect specific areas. http://kingtides.net/participate/test-submit-form/
