Hail Map & Storm Damage Reports: Roofing Leads (NWS)

Get fresh hail, wind damage, tornado and flood reports from the US National Weather Service, minutes after they are filed. Filter by state, hail size and date. Rank the counties hit hardest. Or paste a list of addresses and get a hail and storm history for each one.

No API key. No login. No proxy. The data is public domain.

Built for:

• Roofing and exterior contractors who need to know where hail fell last night, not 90 days later.
• Paintless dent repair (PDR) and auto hail teams chasing hail swaths.
• Public adjusters, insurance and claims teams who need to check "was there hail near this address, and when?"
• Storm restoration marketers planning door knocking, mailers and ads by county.
• Real estate, property managers and inspectors checking storm exposure of a property.
• AI agents and MCP clients that need a simple "storm history for this address" tool.

Why this Actor

Most storm data tools on the Store read the NOAA Storm Events Database. That database is great for research, but it is published months after the storm. Contractors and adjusters need the reports from today and yesterday.

This Actor reads the NWS Local Storm Reports (LSR) feed, the same reports the NWS issues during and right after a storm (spotters, emergency managers, law enforcement, mPING, weather stations). It is updated in near real time and goes back more than 10 years.

	This Actor	Typical NOAA Storm Events scrapers
Delay after a storm	Minutes	About 75 to 120 days
Hail size in inches + common name (Quarter, Golf ball...)	Yes	Partly
Counties ranked by damage	Yes	No
Storm history for an address	Yes (free US Census geocoder built in)	No
API key or proxy needed	No	Varies

Three modes

1. Storm reports

One row per report. Example: every hail report of 1 inch or bigger in Texas and Oklahoma in the last 24 hours.

{
  "mode": "reports",
  "states": ["TX", "OK"],
  "eventTypes": ["hail"],
  "minHailInches": 1,
  "lookbackHours": 24
}

Example row (real report):

{
  "eventType": "HAIL",
  "timeUtc": "2026-05-19T03:37:00.000Z",
  "hailSizeInches": 1.75,
  "hailSizeName": "Golf ball",
  "windMph": null,
  "place": "4 NE Milan",
  "county": "Sumner",
  "state": "KS",
  "latitude": 37.32,
  "longitude": -97.64,
  "magnitudeQualifier": "Estimated",
  "reportSource": "Public",
  "remark": "Report from mPING: Golf Ball (1.75 in.).",
  "nwsOffice": "ICT",
  "mapUrl": "https://www.openstreetmap.org/?mlat=37.32&mlon=-97.64#map=12/37.32/-97.64"
}

2. Hardest-hit counties

One row per county, ranked by a 0 to 100 severity score (big hail and tornadoes count the most). Great for deciding where to send crews or spend ad money.

{
  "mode": "areas",
  "states": ["TX", "OK", "KS"],
  "startDate": "2026-05-01",
  "endDate": "2026-05-31"
}

Example row (real data, May 2026):

{
  "county": "Sherman",
  "state": "KS",
  "severityScore": 81,
  "reportCount": 44,
  "hailReports": 34,
  "maxHailInches": 2.75,
  "maxHailName": "Baseball",
  "windDamageReports": 1,
  "windGustReports": 7,
  "maxWindMph": 82,
  "tornadoReports": 1,
  "firstReportUtc": "2026-05-16T22:29:00.000Z",
  "lastReportUtc": "2026-05-29T23:39:00.000Z",
  "topPlaces": ["Goodland", "13 NNW Ruleton"]
}

3. Address storm history

Paste US addresses (or lat,lon). For each one you get the hail, wind and tornado reports within your radius, the biggest hail and its date, and the closest reports.

{
  "mode": "locations",
  "locations": ["455 N Main St, Wichita, KS 67202", "32.7767,-96.7970"],
  "radiusMiles": 5,
  "historyDays": 1095,
  "minHailInches": 1
}

Example row (real report):

{
  "input": "455 N Main St, Wichita, KS 67202",
  "matchedAddress": "455 N MAIN ST, WICHITA, KS, 67202",
  "stormFound": true,
  "hailReportsNearby": 18,
  "maxHailInches": 2.75,
  "maxHailName": "Baseball",
  "maxHailDateUtc": "2025-09-04T00:40:00.000Z",
  "maxHailDistanceMiles": 2.14,
  "windDamageReportsNearby": 18,
  "stormDays": 19,
  "nearestReportMiles": 0.49,
  "nearbyReports": [ { "timeUtc": "2025-06-17T22:08:00.000Z", "eventType": "TSTM WND DMG", "distanceMiles": 0.49, "place": "1 ESE Downtown Wichita", "remark": "Several powerlines down throughout the metro." } ]
}

Addresses that cannot be found come back as a row with an error message, and you are not charged for them.

Example costs: 500 hail reports = $1.00. 50 counties = $0.50. 100 addresses = $3.00.

What it costs for your business

Storm counts change a lot by season and region, so the table shows the cost for a given number of rows. Use maxResults or a max cost per run to cap spend.

When something else is a better fit

• You only want yesterday's reports on a map and do not need filters or exports. The NWS Storm Prediction Center posts free daily storm report pages and CSV files at spc.noaa.gov/climo/reports.
• You need a hail swath map (where hail fell between reports). This Actor gives you report points, not swaths. Radar based hail map services cover that.
• You need research grade, final storm records. Use the NOAA Storm Events Database. It comes out months later but it is the official record.

Use it from AI agents (MCP)

This Actor works well as a tool for Claude, ChatGPT, Cursor and other MCP clients through the Apify MCP server. Good prompts:

• "Which counties in Texas got hail bigger than 1.5 inches in the last 48 hours?"
• "Check the hail history for these 20 addresses over the last 3 years."
• "Was there wind damage within 5 miles of 32.78,-96.80 in May 2026?"

Inputs are simple, outputs are flat JSON, and failed lookups are free, so agents can call it safely.

Schedule it

Run it every morning with lookbackHours: 24 and send the dataset to Google Sheets, Slack, email, Zapier or Make with Apify integrations. You get a daily storm list for your service area.

Data source and legal notes

• Storm reports: NWS Local Storm Reports, served by the Iowa Environmental Mesonet at Iowa State University. The IEM states its data is public domain. Credit to the IEM is appreciated and is included in every run summary.
• Address lookup: the free public US Census Bureau Geocoder. US addresses only.
• The Actor only uses official public data endpoints. No login, no scraping of private pages, no personal data. The addresses you send are only used for the lookup.
• This Actor is independent. It is not made by or endorsed by NOAA, the NWS, Iowa State University or the US Census Bureau.

Limits and honest notes

• Local Storm Reports are preliminary. They are what people saw and measured. They are not official damage surveys and some storms are never reported. Use them as a strong signal, not as proof of damage.
• Reports are points, not hail swath maps. A report 4 miles away means hail was seen 4 miles away. Bigger radius = more reports, less certainty.
• US and territories only.
• Whole-US runs are limited to 93 days so responses stay fast. Pick states for longer periods.

How to find where hail hit yesterday

Pick your states, set a minimum hail size (for example 1 inch) and a lookback of 24 or 48 hours. You get every hail report with size, time, city, county and coordinates, ready to drop on a map or into your CRM for next-morning door knocking.

How to check hail history for an address

Switch to address mode and paste US addresses. For each one you get the biggest hail nearby, the date, the distance and the nearest storm reports. Useful for roof inspections, insurance claims and real estate checks.

How to get roofing leads from storm data

Use the hardest-hit counties mode to rank counties by a 0 to 100 severity score, then target those ZIP codes with door knocking, mailers or ads. Schedule the Actor daily to get new hail swaths as soon as the NWS posts them.

FAQ

How fresh is the data? New NWS reports usually show up within minutes of being issued.

How far back can I go? More than 10 years with states selected. Address mode up to 10 years.

Why is a hail size like 1.75? NWS reports hail in inches. We add the common name (1.00 Quarter, 1.75 Golf ball, 2.75 Baseball).

Can I get homeowner names or phone numbers? No. This Actor does not collect personal data.

Times are in UTC? Yes. Storms in the evening in the US often show up with the next day's UTC date.
