How this service works
Hail, damaging wind and tornado history for a US street address or lat/lon. Every NOAA Storm Prediction Center storm report within a radius (1-50 miles, default 10) over a lookback window (default 20 years, back to 1955): counts, hail days, largest hail, strongest wind, tornado ratings and track distance, a year-by-year table, and each event with distance and direction.
Output
A JSON object containing: a query echo (lat, lon, radius, years), a period block (start/end dates), a summary section with hail stats (days, reports, largest size, closest event, reports by size threshold), wind stats (days, reports, strongest mph and date, reports above 75 mph), and tornado stats (count, EF rating breakdown, injuries, fatalities, strongest rating and date); a year-by-year array of annual counts; and an array of individual storm events each with date, type, size/speed, distance in miles, and compass direction. eventsTruncated flag indicates if the event list was capped.
Example use cases
Home purchase risk assessment
“Before I make an offer on 456 Elm Street, Norman, OK, can you pull the full severe weather history within 10 miles? I want to know how many tornadoes, the worst hail size, and strongest wind gusts recorded there over the past 20 years.”
Insurance underwriting location check
“I need a severe weather risk summary for lat 35.3395, lon -97.4867 — give me hail days per year, largest hail, tornado count and ratings, and strongest wind speed within 15 miles over the last 25 years.”
Year-by-year storm trend analysis
“Can you get me the year-by-year breakdown of hail, wind, and tornado events within 5 miles of 1600 Pennsylvania Ave NW, Washington DC over the last 10 years so I can see if storms are getting worse over time?”
Technical details
Endpoint
GEThttps://x402-service-production-e242.up.railway.app/severe-weather-history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed historical severe weather data (hail, wind, tornadoes) for a specific US location from NOAA's official Storm Prediction Center records, especially for property risk assessment, insurance underwriting, real estate due diligence, or climate trend analysis. It covers data back to 1955 and returns both summary statistics and individual event records with precise distance and direction — more granular than general weather risk scores.
Side effects
- Invalid or unresolvable address returns an error or empty result
- Lat/lon outside the contiguous US may return no data
- Radius outside 1–50 miles range may be rejected or clamped
- Lookback years beyond available historical data (pre-1955) may be silently truncated
- Payment failure (non-402-compliant client) results in a 402 Payment Required response
- Network timeout from Railway hosting under high load
