US Hail & Storm Damage Reports (NWS + NOAA Radar Hail)

Get every hail, damaging-wind and tornado report in the US for any date range, state, or radius around your service area, as clean JSON, CSV or Excel. Each run can also add NOAA NEXRAD radar hail footprints, which catch hail that nobody phoned in, and county-by-day roll-ups.

Built for roofing and exterior contractors, storm-restoration and paintless-dent-repair crews, public adjusters, insurers, storm-marketing agencies, and AI agents.

What you get

Record type	Source	What's in it
storm_report	Official NWS Local Storm Reports, the ground-truth reports from spotters, law enforcement, the public and NWS offices, served by the Iowa Environmental Mesonet (Iowa State University)	Time (UTC), state, county, place ("2 N Garland"), lat/lon, hail size (inches + "golf ball" label), wind mph, NWS severe flag, measured/estimated, who reported it, the NWS remark ("roof blown off a barn"), the NWS product link, and a map link
radar_hail_cell (optional)	NOAA NEXRAD Level-III hail signatures via the NCEI Severe Weather Data Inventory	Grid cell (~7 mi) per day with max radar-estimated hail size, severe-hail probability, number of detections, first/last time, and radar sites
county_summary (optional)	Roll-up of the reports returned	Per county per day: report counts, max hail, max wind, first/last time, sample places

All data is US-government or university public-domain weather data. No personal data, no logins, no proxies.

Example uses

• "Every hail ≥ 1 inch in Texas and Oklahoma in the last 3 days" → a daily scheduled run for canvassing routes
• "Anything severe within 40 miles of my shop last night" → a center point plus radius
• Insurance or claims checks: "was there hail at this location on this date?"
• Feed an AI agent or CRM with fresh storm counties every morning

Input

Field	Default	Notes
states	all	2-letter codes, e.g. ["TX","OK"]
lastDays	3	Used when startDate is empty
startDate / endDate	—	YYYY-MM-DD (UTC), end inclusive, max 31 days per run
eventCategories	hail, wind, tornado	Also flood, winter, marine, other
minHailInches	0	1.0 = quarter size (NWS severe threshold)
minWindMph	0	Wind-damage reports without a speed are kept
severeOnly	false	Hail ≥ 1", wind ≥ 58 mph or wind damage, or a tornado
centerLat / centerLon / radiusMiles	— / — / 25	Radius filter; adds distanceMiles
includeRadarHail	false	Needs states or a center point
minRadarHailInches / minRadarSevereProb / radarGridDegrees	1.0 / 50 / 0.1	Radar thresholds
includeCountySummary	true
sortBy	newest	newest, largestHail, nearest. Ground reports always come before radar cells
maxItems	50	Cap on storm records (ground + radar)

Pricing

Pay per event: you pay per storm record saved and per county summary saved, plus a tiny Apify start fee. There is no monthly contract. Set a max cost per run in Apify Console, and the Actor stops cleanly when it is reached. See the price on this page's pricing tab.

Good to know

• Preliminary data. Local Storm Reports are preliminary and NWS can correct them later. Times are UTC.
• Radar hail is an estimate. NEXRAD maximum hail size comes from an algorithm and often runs larger than what reaches the ground. Use it to find likely footprints and confirm with ground reports.
• Radar cells are scoped with approximate state bounding boxes, so cells near a state line can belong to the neighbouring state. Ground reports carry their exact state.
• Coverage depends on who reported: rural hail can be missing from ground reports but present on radar.
• Not for life-safety use. For active warnings, use weather.gov.
