gov.disaster-declarations

FEMA federal disaster & emergency declarations — every federally declared disaster since 1953, including the ones declared this week. Filter by state (2-letter), disasterNumber, declarationType (DR=major disaster, EM=emergency, FM/FS/FW=fire management), incidentType (e.g. Hurricane, Fire, Flood, Severe Storm), county (5-digit FIPS), fiscal year (fyDeclared), and declaration date range (fromDate/toDate, YYYY-MM-DD). With no filter, returns the most recent declarations nationwide. Returns the total matching count plus records (one per designated county/area) with the declaration string, disaster number, title, incident type, declaration + incident begin/end + closeout dates, designated area, county FIPS, FEMA region, and the assistance programs authorized (Individuals & Households, Individual Assistance, Public Assistance, Hazard Mitigation). Free, public-domain (OpenFEMA). Distinct from gov.risk-index (modeled future risk) and gov.nfip-claims (realized flood losses): this is the official federal-response record — for disaster-response logistics, eligibility checks, insurance, and emergency-management workflows.
