U.S. severe weather API

Historical, live, and forecast severe weather intelligence.

API-first severe weather intelligence for developers and enterprise teams working with property, claims, risk, and operations data. Pro teams can turn evidence into polished, verifiable PDF reports from the same platform.

Product

Peril data for past, present, and future.

Query any location in the U.S. for historical evidence, live signals, and forecast guidance across severe-weather workflows.

Hail

Radar-derived hail, storm reports, and warning context.

Heavy rain

Rainfall estimates and flood-related context near a property.

Damaging wind

Wind reports, observations, and severe-storm evidence.

Tornado context

Tornado reports, warnings, outlooks, and rotation guidance.

Pro reports

Customer-ready weather evidence, not raw data exports.

Build a single-date report from the same observed evidence used by the API. Preview candidate events, choose the perils that belong in the final packet, and generate a polished PDF with a source-backed snapshot.

Built for handoff

Generate a polished evidence packet that reads clearly for customers, adjusters, and internal reviewers.

Evidence stays traceable

Each PDF is backed by a stored snapshot and supporting source context.

Tuned to the event

Customize each report by location, event date, search radius, and the perils that matter for the review.

Radar MRMS

Hail, rain, and rotation raster artifacts.

Reports SPC

Hail, wind, and tornado report context.

Reports NWS Local Storm Reports

Ground reports and event narratives.

Records NOAA Storm Events

Official historical severe-weather records.

Warnings NWS Warnings

Warning polygons and peril context.

Forecast Forecast models

Forward-looking severe-weather guidance.

Providers

Multiple weather feeds refined and simplified into one.

Storm Evidence normalizes radar, reports, warnings, records, and forecast products so your team can ingest one consistent API instead of stitching together raw feeds.

Use cases

For weather-backed decisions.

Claims triage

Prioritize reviews with property-level hail, wind, rain, and tornado context.

Property risk

Enrich assets with historical and forecast weather exposure.

Restoration workflows

Qualify storm activity before outreach, inspections, and dispatch.

Operations

Validate weather disruption near facilities, routes, and field teams.

Plans

Pricing plans that fit every use case.
