NASA Warns Moon’s 18.6-Year Wobble Could Triple U.S. Coastal Flooding by Mid-2030s

Summary
Mid-2030s high-tide flooding could hit a majority of U.S. coastlines 3 to 4 times more often, with calm-day inundation clustering into a few months rather than arriving with storms.
The trigger is the moon’s 18.6-year orbital wobble entering its amplifying phase just as decades of sea-level rise have lifted the baseline, pushing ordinary high tides past local flood thresholds.
NOAA says these are usually minor floods one by one, but repeated events can strain roads, drainage systems and low-lying property; some East Coast tide stations could see nuisance-flood days rise 33% to 125%.
Local impacts will vary with harbor shape, coastal geography and land subsidence, leaving planners and property owners to rely on site-specific tide and flood outlooks rather than a single national pattern.
With the moon's wobble timing floods to daily commutes, could sunny-day flooding soon paralyze coastal city traffic without a drop of rain?
While oceans rise, coastal cities are rapidly sinking; will this hidden underground collapse trigger a tidal flooding tipping point faster than predicted?
