Enter any address in Dillingham Census Area, Alaska to see its FEMA flood zone
Coastal flooding and storm surge are the primary flood concerns in Dillingham Census Area County. Over the past 30 years, NOAA Storm Events data shows coastal flood events occurred 6 times, storm surge/tide events occurred 5 times, and general flood events occurred 4 times.
Recent events illustrate these risks. For example, a coastal flood event on November 1, 2022, was associated with a low-pressure system moving inland from the Bering Sea, bringing strong onshore winds and minor coastal flooding to portions of Bristol Bay. Another coastal flood event on November 14, 2023, was linked to a strong low-pressure system developing west of the Aleutian Chain, bringing high winds and seas to the western coastline.
Residents with properties along the coast, particularly those in areas prone to storm surge and tidal influences, should pay close attention to flood risks. Homeowners without a Base Flood Elevation (BFE) may also face increased vulnerability.

Coastal Flood — Nov 14, 2023
A strong low developed to the west of the Aleutian Chain late on the evening of November 13th and moved into the western Bering Sea, eventually moving east into the western coastline of Mainland Alaska by the afternoon of November 15th. Strong winds gusting as high as 77 mph affected portions of the central Aleutians as the low moved to the north while even stronger winds and seas up to 40 fee...
Storm Surge/Tide — Jul 23, 2022
A low pressure moving through the Bering brought increased surf to the Bristol Bay coastline. A tight pressure gradient due to the low brought gusty winds and helped to push the water towards the coastline raising the water levels.
Coastal Flood — Nov 1, 2022
A frontal system tracking east across the Bering Sea at the tail end of October reached the Southwest Alaska as a new low developed along the boundary between November 1st and 2nd and strengthened up until moving ashore near the Kuskokwim Delta. This system brought a multitude of impacts to portions of the region as it headed inland, ranging from minor coastal flooding due to strong onshore wi...
Coastal Flood — Dec 8, 2021
A north to south oriented frontal boundary brought periods of heavy snow, avalanche conditions, lowered visibilities, high winds and strong surf from west to east over the course of several days as the front shifted slowly east and developed into a triple point low over the western Gulf. Strong upper level dynamics and a deep moisture fetch made this an impactful storm for southern Alaska.
Storm Surge/Tide — Dec 24, 2015
A strong low pressure system entered the Aleutian Islands at 976 mb the morning of 6/23. It rapidly strengthened to 955 mb and moved across the Bering Sea. This storm brought strong winds to the Aleutians and Pribiliof Islands, and caused blizzard conditions along the West Coast with snow ahead of the front. One death attributed to whiteout conditions occurred during this time. Prolonged period...
