Data sources and attribution
WeatherWRX builds its forecasts, alerts, and map layers from named public forecast models, government warning authorities, and licensed data services rather than an undisclosed blended source. This page lists every provider we use, what it supplies, and the license and attribution that apply. Data exported from WeatherWRX (calendar feeds, spreadsheets, and API responses) references this page as its source register.
