How StormSync VT/OI has performed during real-world severe weather events. Updated as events occur.
The Storm Prediction Center issued a Moderate risk for portions of the Midwest including Indiana and Illinois. This outbreak was also notable for the issuance of the first-ever CIG2 risk under SPC's updated outlook system. Multiple tornado warnings were issued across the affected region throughout the event.
A Tornado Emergency was issued for the City of Knox. StormSync caught and displayed it correctly — rank 115, correct pink color coding, overlay notification fired — ahead of weather broadcasters and community monitors. The first live Tornado Emergency ever processed by the app.
The NWWS-OI connection remained stable throughout the event. All tornado warnings, severe thunderstorm warnings, and associated products were received and displayed in real time with no missed alerts or dropped connections.
All tornado sub-types were correctly identified and color-coded throughout the outbreak. Severity rankings sorted correctly across simultaneous active warnings.
When an existing tornado warning was upgraded during the event, the upgraded product was not reflected as an updated card in the UI. The warning remained visible but the upgrade action was not shown. Known issue — being addressed in v0.0.21 or v0.0.3.
For a v0.0.2 early beta, performance during this event was strong. Core functionality — real-time feed, VTEC parsing, tier detection, overlay notifications — all worked correctly under live outbreak conditions. The upgrade display issue is the only notable gap and is already tracked for the next release.
