⚠ VORTEX uses real atmospheric data from Open-Meteo (model blend) and NWS alerts. Tornado probability is calculated using SPC's Significant Tornado Parameter formula and related indices. This is a research/situational-awareness tool — NOT an official NWS forecast. Always follow NWS, SPC, and local emergency management guidance for life-safety decisions.
