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.

The five hazards

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.
Forecast zones with the name of the county give 136 of the 592 events. 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.

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. FEMA counts 11 multiple-loss properties in the county (2 Aug 2026). 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.
The labels and the ratings are those of FEMA. Expected Annual Loss is a figure for a whole county. It is not a figure for a property. How to read the National Risk Index
