Bethel Census Area Flood History

Coastal Flood — Jan 12, 2025

A large and strong low moved up the North Pacific into the eastern Bering Sea, peaking in strength as it moved up the Kuskokwim Delta. The orientation of the low's front was ideal for strong winds across Southcentral Alaska. Damaging winds were observed across parts of the Turnagain Arm, Kenai Peninsula, Matanuska Valley, and Anchorage. A significant amount of moisture also was transported by t...

Coastal Flood — Jan 9, 2025

A north Pacific low moved into the Bering and tracked northeastward into the Kuskokwim Delta Coast. Southerly winds increased to gale force strength and combined with high tides and a lack of sea ice to cause coastal flooding that inundated many boardwalks and low lying areas in Kwigillingok, Alaska on January 10th. Snow machine trails were submerged as well.

Coastal Flood — Dec 18, 2024

A deep low pressure system with multiple imbedded shortwaves moved into the Bering on December 18th, bringing precipitation and gusty winds to the Aleutian Islands and inland areas of Southwest Alaska. Winds were oriented in a southerly direction in the Kuskokwim Delta, allowing for coastal flooding to impact communities along the shore south of Bethel. Tides were elevated due to a recent full ...

Coastal Flood — Aug 15, 2024

Two Bering Sea low pressure systems tracked into Western Alaska from August 15 through 18th bringing a period of nearly-persistent southerly winds which led to storm surge and coastal flooding along the Kuskokwim Delta coast and backed up flow along the lower Kuskokwim River. Abundant moisture drawn from the tropical West Pacific by both lows squeezed out moderate to heavy rain in Southwest Ala...

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...
