The Washington Post discusses King tides, boosted by sea-level rise, are flooding communities along the East Coast. What once happened only with a storm is now routine on fair-weather days.
But there was no storm to be found. In fact, many places enjoyed pleasant weather and sunshine. Yet coastal flood advisories plastered the coast, forcing road closures and flooding properties.
The culprit? King tides. A name informally attached to extra-high tides spurred by astronomical alignments, king tides often reach their peak in the fall. Decades ago, their impact was minimal. But added to the background of climate-driven sea-level rise, nowadays they are routinely problematic.
