For each disaster, the wait from the declaration to the first federal obligation (amber), then the federal share obligating after that (teal), on a shared 5-year scale. Typical wait to the first obligation here: about 67 days. An obligation is the federal share committed to the recipient state, not funds disbursed to the locality, which comes later and is not shown.

Valid registrations are households that applied within a designated Individual Assistance area; approved counts and dollars are the households FEMA found eligible under the Individuals and Households Program.

Emergency declarations issued by the governor of this state, which are separate from and usually precede a federal declaration. A declaration is listed here when NOAA Storm Events recorded reports of the matched hazard in this jurisdiction while the order was in effect. That is evidence of local impact during a declared state emergency. It is not a statement that the governor named this jurisdiction in the order, since most state declarations apply statewide and name no localities at all. Hazard categories come from the order text. Damage figures are NOAA storm report estimates for this jurisdiction only, not the cost of the declaration.

Major disaster (DR). The big one. Opens the full toolbox: repair money for public infrastructure, help for households, and mitigation funding to reduce the next loss.
Emergency (EM). Narrower and usually faster, for protective work before or during an incident. Capped, and rarely brings household assistance. Nearly every county has one from COVID-19.
Fire management (FM). Cost sharing to fight a wildfire as it burns. Not a disaster declaration, and it does not open recovery programs.

Drawn from FEMA's OpenFEMA Disaster Declarations Summaries, rebuilt each week. A declaration is counted here once for each designated area it names, so a single disaster covering many localities is counted in each one. For that reason these jurisdiction counts do not sum to Wisconsin's statewide total. This page counts declarations that named this jurisdiction as a designated area. Totals cover complete fiscal years (Oct 1 to Sep 30). Declarations from the fiscal year still in progress are listed in the tables on this page but are not counted in the totals until the year is complete. Uses OpenFEMA data but is not endorsed by or affiliated with FEMA.
