Weld County within Colorado. Dots: HailTornadoFloodWind event locations in the kept record. Boundaries: US Census Bureau.

NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 29 Sep 2026; NFIP claims as of 8 Sep 2026.

Weld County, Colorado, has 1,912 weather events in the NCEI Storm Events record since 1950, most of them hail.

That is 48.0 events per 100 square miles, in line with the Colorado figure of 49.4, and 56.2 per 10,000 residents against 88.1 statewide.

49 events fall in the 12 months to 30 Jun 2026. NCEI attributes 5 deaths and 102 injuries to events in the county, with property damage estimated at $401M and crop damage at $35M.

FEMA has designated the county in 16 federal disaster declarations since 1953; the most recent is Covid-19 Pandemic (major disaster, 28 Mar 2020).

National Flood Insurance Program policyholders in the county filed 194 claims since 1978, of which 145 were paid, totalling $5.7M (about $39K per paid claim). FEMA counts 325 residential flood policies in force.

FEMA's National Risk Index rates the county's overall risk as "Relatively Moderate" and its expected annual loss as "Relatively Moderate" ($105M a year across 18 hazards).

Recorded events in Weld County by decade and hazard group. HailTornadoFloodWindLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 964 events in the 20 years to 2025 against 672 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
