@chswx LDM Parser

(test suite in progress, don't read much into this yet!)

A series of scripts to ingest and relay NWS watch/warning/advisory products via Unidata’s LDM. Will eventually expand to forecast and METAR processing as well; baby steps for now, though.

What’s done

• VTEC (Valid Time Extent Code) awareness
• Rudimentary Twitter support
• Relays for most common hazardous weather advisories

What’s in the works

• A variety of bug fixes to VTEC support
• Support for watch probabilities (WWUS40)
• Support for additional output endpoints
• Storm-based warnings via PostGIS polygon queries
• Tornado/flash flood emergency detection
• Impact-based warnings (TORNADO…HAIL…WIND tags)
• Moving to a totally pub/sub architecture
• Awareness of conditions via METAR ingest
• Awareness of forecast updates

Pie in the sky stuff

• Configurable UI
• Portable installation

Licensing, warranty, etc.

Licensing TBD. Code is pretty lousy and should not be used for life and death applications. No warranty implied. Use at your own risk.

Many Thanks

Many thanks to @blairblends, @edarc and @UpdraftNetworks for infrastructure and seeding the initial code for this project.
