NWWS-RS is a self-hosted NOAA Weather Wire Service (NWWS-OI) platform developed by Fahrenheit Research and distributed as a single static binary. The software connects to the National Weather Service's lowest-latency public text-product feed, delivering warnings seconds after a Weather Forecast Office issues them, typically well ahead of the public CAP and REST mirrors. Its strict parser handles every bulletin component, including WMO headers, AWIPS/PIL identifiers, UGC codes, VTEC and HVTEC tags, message segments, warning tags, polygons, and storm motion data. A supervised ingest daemon manages the connection and processing pipeline, while built-in deduplication and archiving organize the incoming products for later retrieval. Parsed data is served back over a local HTTP API, complemented by a live Server-Sent Events stream that enables real-time consumption by dashboards, alerting tools, and other downstream applications. The platform's core is written in Rust, with Python bindings provided for scripting and integration alongside a command-line interface for direct operation; according to the publisher, this architecture makes it 19 times faster than pyIEM. NWWS-RS is currently at version 0.1.1, with two versions released to date. As a self-hosted solution, it gives operators full control over their weather-data infrastructure without reliance on third-party mirrors. The software falls within the weather data processing and alerting category, and its use cases include rapid severe-weather warning dissemination, automated monitoring of NWS text products, research into forecast and warning issuance, and integration of low-latency meteorological feeds into custom applications. By combining strict parsing, deduplication, archival storage, and live streaming in one binary, NWWS-RS consolidates the complete pipeline from raw NWWS-OI feed to structured, queryable, and streamable weather information, making it suitable for developers, emergency managers, and weather enthusiasts who need timely and reliable access to official warnings.
