🌪️ NOAA Weather Alerts Intelligence — real-time severe-weather alerts with AI risk scoring

Extract real-time weather alerts from NOAA's National Weather Service — tornado, hurricane, flood, severe thunderstorm and winter-storm warnings across every US state — as clean, structured data with an AI risk score (0–100) on every alert. Get severity, urgency, certainty, affected areas, timing and official instructions in one row, so insurers, emergency teams, logistics and operations can act on the most critical threats first. Export to JSON/CSV/Excel, run on a schedule, call via API, or connect to Make, Zapier or n8n.

🌪️ What is the NOAA Weather Alerts Intelligence Scraper?

It turns the live feed from NOAA's official api.weather.gov into a structured, scored dataset. Filter by severity, urgency, certainty, event type, US state, region, NOAA zone or a single lat/long point, and the actor returns every matching alert with its full text, affected areas, effective and expiry times, and a 0–100 risk score that ranks the most dangerous, most imminent events first. The data is free US government data — no API key and no login required.

What data does it extract?

• Event & headline (event, headline) plus the full description, instruction and recommended response
• Severity, urgency and certainty (severity, urgency, certainty) — the core threat dimensions
• Status, message type and category (status, message_type, category)
• Affected area (area_description, affected_zones) and geocodes (same_codes, ugc_codes)
• Timing: sent, effective, onset, expires, ends
• Source (sender, web) and a unique alert_id
• Geometry (geometry_type, coordinates) for mapping
• AI risk score (0–100) (risk_score) combining severity, event criticality, urgency and time-to-onset

⬇️ Input

Every field is optional — leave them empty to pull all active alerts, or narrow down:

Field	Description
severity	Filter by Extreme, Severe, Moderate and/or Minor
urgency	Filter by Immediate, Expected and/or Future
certainty	Filter by Observed, Likely, Possible and/or Unlikely
eventType	Specific events, e.g. Tornado Warning, Flood Warning
state	US state codes, e.g. CA, TX, NY
point	A latitude,longitude point, e.g. 39.7456,-97.0892
zone	A specific NOAA zone ID, e.g. CAZ006
region	Marine/region code (Alaska, Atlantic, Great Lakes, Gulf, Pacific, Pacific Islands)
activeOnly	Only currently active alerts (default true)
status / messageType	Filter by actual/exercise/test and alert/update/cancel
maxResults	Cap the run (1–1000, default 100)
includeRiskScore	Calculate the 0–100 AI risk score (default true)

💡 Use cases

• 🏢 Insurance & risk assessment: track Extreme and Severe events by state to flag exposure, trigger claims workflows and price weather risk.
• 🚨 Emergency management & safety: monitor Immediate, Observed tornado and flash-flood warnings and route the highest risk scores to responders first.
• 🚚 Logistics & operations: anticipate hurricane, blizzard and ice-storm disruption along routes and reroute before alerts hit.
• 🏗️ Construction, agriculture & events: watch heat, wind, frost and storm advisories to protect crews, crops and outdoor schedules.

🧮 How the risk score works

A transparent 0–100 score combining severity (Extreme/Severe/Moderate/Minor), event-type criticality (a Tornado or Flash Flood Warning scores far above a Frost Advisory), an urgency multiplier (Immediate is weighted up, Future down) and time to onset (sooner is riskier). The result lets you sort by risk_score and act on the most dangerous, most imminent alerts before anything else.

❓ FAQ

How do I get NOAA weather alerts? Set optional filters for severity, event type, state or location, then Run. You get every matching alert with full text, affected areas, timing and an AI risk score.

Do I need an API key? No. It reads free public data from NOAA's National Weather Service (api.weather.gov) — no key, no account, no login.

Where does the data come from? Directly from NOAA / the US National Weather Service official alerts API, the same source that powers government weather warnings.

What events does it cover? All NWS alert types — tornado, hurricane, tsunami and flash flood warnings, severe thunderstorms, blizzards, ice and winter storms, plus heat, wind, frost, fog and marine advisories.

Can I monitor a specific area? Yes — filter by state codes, a NOAA zone ID, a region, or a precise point (latitude,longitude) to watch exactly where you operate.

What is the risk score? A 0–100 ranking built from severity, event criticality, urgency and time-to-onset, so the most dangerous and imminent alerts rise to the top. Set includeRiskScore to false to skip it.

Can I get only currently active alerts? Yes — activeOnly defaults to true. You can also filter status (actual/exercise/test) and messageType (alert/update/cancel).

How many alerts can it return? Up to your maxResults cap (max 1000 per run).

Can I run it on a schedule or via API? Yes — schedule frequent runs in Apify (e.g. every few minutes during severe weather), call it via the API/SDK, or connect it to Make, Zapier or n8n for instant notifications.

Is this legal? Yes — NOAA weather alert data is public US government data. Use it responsibly and follow applicable terms; it is not a substitute for official emergency guidance.
