Product Description

The meticulously designed Tempest Weather System leverages powerful machine learning and state of the art modeling capabilities to provide the most precise, local forecast available. WeatherFlow's proprietary AI and data science techniques leverage machine learning to process weather data from your backyard, comparing it against trusted data sources. The result is a more accurate local forecast that only gets better over time. The sensor device has no moving parts, is completely wireless, easy to install, and instant access to your weather data via free iOS and Android apps.
