Coastal flooding and riverine flooding are the primary flood concerns in Grays Harbor County. Recent events include coastal flooding in November 2024, driven by high tides and low atmospheric pressure, and significant riverine flooding in January 2022, caused by a series of winter storms and atmospheric rivers. Earlier in January 2021, persistent low-pressure systems also led to atmospheric rivers and heavy rainfall, contributing to flood conditions.
National Flood Insurance Program (NFIP) data indicates a substantial number of claims in Zone A, with an average payout of $15,128 and an average water depth of 3.5 feet.

Coastal Flood — Nov 13, 2024
A combination of low atmospheric pressure and high astronomical tide produced minor to moderate coastal flooding on the Washington coast and in south Puget Sound.
Flood — Jan 6, 2022
A strong and persistent upper-level low-pressure system developed over the northern Rockies and southern Canada and then slowly migrated westward while continuously directing the jet stream and primary storm track at Washington State. This strong low-pressure system resulted in a 21-day period of a series of winter storms, wind storms, and atmospheric rivers that battered Washington State in ra...

A series of storm systems affected Western Washington around the middle of January, with dangerous beach conditions expected to set up by January 12. This combined with King Tides led to the potential for coastal flooding through the 13th.
Flood — Jan 12, 2021
The period from January 10 to 16 continued a pattern of a strong and persistent Aleutian Low pressure system in the eastern Pacific that began December 29, 2020 and which directed the jet stream and primary storm track at Washington State. This resulted in a series of atmospheric rivers and wind storms that battered Washington State. Water vapor transport into Washington State averaged 160-200...
