Yukon-Koyukuk Census Area, Alaska Storm events, disaster declarations and flood insurance claims on record

This page is a county record of past events and claims. It does not show the flood zone or the risk of an address. For the flood map of an address, use FEMA's address search (opens in a new tab).

NCEI has no storm event on record for Yukon-Koyukuk Census Area, Alaska, from 1950 through 30 Jun 2026.

FEMA has 21 disaster declarations on record for the county from 1964 through 1 Oct 2026. The newest is DR-4893 of 22 Oct 2025.

OpenFEMA has 72 NFIP claims on record for the county from 1978 through 8 Sep 2026. The NFIP paid $3.3 million on the claims of the years that have an amount in the table.

The NWS collects event reports from a variety of sources, which include (but are not limited to): county, state, and federal emergency management officials, local law enforcement officials, SKYWARN spotters, NWS damage surveys, newspaper clipping services, the insurance industry, and the general public, among others.

The National Weather Service reports property and crop damage estimates using available data at the time of event reporting. These values should therefore be considered broad estimates. Damage amounts are not adjusted for inflation.

Zone (NWS Forecast Zone): A zone is a geographic area defined by the NWS for issuing forecasts, watches, and warnings. While zones often align with counties, they can also represent smaller or subdivided areas within a county to account for differences in weather conditions, such as elevation or proximity to water. Larger-scale events—such as heat, cold, drought, and winter storms—are typically recorded by zone.

A hazard name opens the page of that hazard for the county. A hazard has a page from 10 events. The year 2026 has the events through 30 Jun 2026 only.

NCEI records many Alaska events for areas that do not match boroughs and census areas. The state page counts all of them. A county count has the events that NCEI gives to the county. It also has the events of a forecast zone that has the name of the county. A zone with another name counts for the state only.

In Alaska, storm events are reported and organized differently than the rest of the U.S; instead of using counties or boroughs for search and reporting, many events are recorded over large, sparsely populated areas that do not align consistently with borough boundaries.

The dataset includes declared recovery programs and geographic areas (county not available before 1964; Fire Management records are considered partial due to historical nature of the dataset).

Flood insurance claims (NFIP)

OpenFEMA has 72 NFIP claims on record for Yukon-Koyukuk Census Area from 1978 through 8 Sep 2026.

The NFIP paid $3,338,675 on 55 claims in the years that have an amount in the table.

A year with fewer than 5 claims shows the count of claims and no amount. A year with 1 to 4 claims with a payment shows no amount either. Such an amount could point to one property. The amount is the sum of the building, contents and increased cost of compliance payments. How FEMA redacts NFIP claims

The National Risk Index dataset leverages available source data for natural hazard and community risk factors to develop a baseline relative risk measurement for each United States county and Census tract.

The rating is a qualitative categorization that describes the community in comparison to all other communities at the same level, ranging from “Very Low” to “Very High.”

The National Risk Index data are meant for planning purposes only.
