NCEI has 838 storm events on record for La Crosse County, Wisconsin, from 1950 through 30 Jun 2026.

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.

Forecast zones with the name of the county give 166 of the 838 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.

The amount is the sum of the building, contents and increased cost of compliance payments. FEMA counts 13 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.
