Weather

freeliveanalytics

From raw conditions to predictive intelligence. weatherdata (free) carries air/track temp, humidity, pressure, wind, and rainfall; the weather.rain_onset / weather.rain_cleared events fire on rainfall transitions. The Analytics-tier weather.* feeds add forecast-driven strategy signals — when the field splits wet vs. dry, when a compound crossover is imminent, and per-driver tyre-mismatch alerts.
