In low-lying areas, perigean spring tides can result in minor flooding. This flooding, which can lead to road closures, overwhelmed storm drains, and compromised infrastructure, is commonly called
According to NOAA,on average, nuisance flooding has increased about 50 percent in the last 20 years.
Major coastal flooding can occur when perigean spring tides occur simultaneously with strong onshore winds and barometric pressure changes from a coastal storm. Coupled with sea level rise, both minor and major coastal flood risks are expected to increase.
