Tempest Weather System
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 - guaranteed. No moving parts, completely wireless, simple installation, with instant online access to weather data via free iOS and Android apps.
While general weather apps abound, the Tempest app is different. It feeds real-time observed weather data from your backyard into a machine learning system to dramatically improve forecast accuracy where it matters most – your home.
