But high tide flooding is not restricted to these two sites. As the map below illustrates, virtually all coastal areas on the Northern Neck will experience greater high tide flooding. Red represents minor flooding events, according to NOAA, “which typically presents a low threat of property damage and no direct threat to life.” Yellow, on the other hand, represents major flooding events, events “which typically presents a significant threat to life and property.”
What is high tide flooding? According to NOAA,
High-tide flooding occurs in low-lying coastal areas during extreme high tides (also known as perigean or king tides). These tides occur a few times per year when the sun, moon, and earth align. By definition, a coastal storm is not necessary for high-tide flooding to occur. However, even relatively weak onshore winds can increase the level of flooding.
