They submerge stairways to the beach, overwhelm boardwalks, surge into storm-drain systems, flood roads, and even crash against the windows of waterfront buildings.

We watch as boats, birds, and marine mammals move with the pull of the high and low tides outside our office windows. King Tides are the highest tides of the year, and they demand extra attention.
