The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ![Chris The Dev](https://raw.githubusercontent.com/chriswakefield87/appstore-screenshot-translator/main/assets/actor-banner.png) ## NOAA Weather Data Scraper & Normalizer Fetch, normalize, and enrich weather data from NOAA's National Weather Service API — completely free, no API key required. ### What It Does This actor pulls live weather alerts and detailed point forecasts from the NWS public API and transforms raw data into clean, enriched, and analysis-ready output. #### Key Features - **Weather Alerts** — Active watches, warnings, and advisories for any US state - **Point Forecasts** — 7-day detailed forecasts for any lat/lon coordinates - **Smart Normalization** — Maps 80+ raw NOAA event types into 18 standardized categories - **Risk Scoring** — Composite severity × urgency × certainty score (1-64 scale) with CRITICAL/HIGH/MODERATE/LOW labels - **Unit Conversion** — Fahrenheit→Celsius, mph→kph, mph→m/s built in - **Clean Output** — Human-readable summary tables + structured JSON + machine-readable stats ### Input Parameters | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | `searchType` | select | ✅ | `alerts` | `alerts`, `forecast`, or `alerts_and_forecast` | | `stateCode` | select | — | All states | Filter alerts by US state (e.g. CA, TX, FL) | | `latitude` | string | forecast only | — | Latitude for point forecast (e.g. `40.7128`) | | `longitude` | string | forecast only | — | Longitude for point forecast (e.g. `-74.006`) | | `maxResults` | integer | — | `50` | Maximum results (1–500) | | `severityFilter` | select | — | All | Filter alerts by severity: Extreme, Severe, Moderate, Minor | ### Example Input ```json { "searchType": "alerts_and_forecast", "stateCode": "CA", "latitude": "37.7749", "longitude": "-122.4194", "maxResults": 25, "severityFilter": "Severe" } ```` ### Example Output #### Summary Table (KVS OUTPUT) ``` ==================================================================================================== NOAA WEATHER ALERTS — NORMALIZED SUMMARY ==================================================================================================== Total alerts: 8 Categories: Heat:3, Fire Weather:2, Flood:1, Wind:1, Marine:1 Risk levels: HIGH:3, MODERATE:3, CRITICAL:2 # Event Cat Sev Urg Risk Risk Label Area ─── ────────────────────────────── ────────────── ────────── ────────── ──── ────────── ───────────────────────── 0 Excessive Heat Warning Heat Severe Expected 36 CRITICAL San Francisco Bay Area 1 Heat Advisory Heat Moderate Expected 18 HIGH Central California 2 Red Flag Warning Fire Weather Severe Expected 36 CRITICAL North Bay Mountains ``` #### Structured JSON (Dataset) ```json { "id": "urn:oid:2.49.0.1.840.0.abc123", "event": "Excessive Heat Warning", "eventCategory": "Heat", "headline": "Excessive Heat Warning issued for Bay Area", "severity": {"label": "Severe", "score": 3}, "urgency": {"label": "Expected", "score": 3}, "certainty": {"label": "Likely", "score": 3}, "riskScore": 27, "riskLabel": "HIGH", "effective": "2026-07-15T12:00:00Z", "expires": "2026-07-18T00:00:00Z", "areaDescription": "San Francisco Bay Area" } ``` #### Forecast (Dataset with unit conversions) ```json { "name": "Monday", "temperature": 92, "temperatureC": 33.3, "windSpeed": "10 to 15 mph", "windSpeedKph": 24.1, "windSpeedMs": 6.7, "shortForecast": "Sunny and hot" } ``` ### Use Cases - **Insurance & Risk** — Monitor severe weather events for claims forecasting - **Agriculture** — Track freeze/frost warnings and heat advisories for crop planning - **Logistics & Transportation** — Route around weather hazards - **Emergency Management** — Aggregate alerts by severity and risk score - **Weather Apps & Dashboards** — Power consumer-facing weather products - **Research & Analysis** — Historical weather pattern studies ### Data Source All data from the [NOAA National Weather Service API](https://www.weather.gov/documentation/services-web-api) — a free, public, no-key-required REST API. Data is updated in real-time. ### Pricing Pay per result — $2.00 per 1,000 results. Each weather alert or forecast period counts as one result. *** Built by [Chris The Dev](https://apify.com/wakey7dev) • July 2026 # Actor input Schema ## `searchType` (type: `string`): Choose what type of weather data to fetch.
