High Tide Flooding
High tide flooding is the overflow or excess accumulation of water that covers typically dry coastal land and occurs during high tides. As relative sea levels rise, high tide flooding is occurring more frequently, even on sunny days. High tide flooding creates short-term impacts like road closures, overflowing storm drains, and temporary business closures. Over the long term, recurrent high tide flooding causes more severe impacts, like damage to below-ground infrastructure and degraded wetlands. NOAA's high tide flooding information can help users plan for and mitigate impacts.

The intersection of Kilihau street and Kakoi street is flooded with water during high tide. Above normal water levels were due to a perigean spring tide and swells from Hurricane Erick.
