Storms don’t always coincide with high tides, but today’s nor’easter did.
Tide was 2.2m (7.2 ft) late this morning (see this link for tide chart), and near the causeway to Oak Island the road was covered with several inches of water. In 8 years of watching storms here, this was the highest storm surge we’ve seen, with water flowing completely over the road.
