Getting started with Wx Horizon is as easy as 1-2-3. Sign up for Wx Horizon Pro, select your virtual road weather forecast points, and install your Cast devices, and you're ready to start making data-driven decisions.
Sign Up for Wx Horizon
Choose your virtual road weather forecast points. These are the points on your network where more data would benefit decision-making, but you may not be ready to install sensors.
Install your GroundCast sensors at locations that matter most to you. Choose locations that are representative of the surrounding area and where weather events are challenging to manage. Your sensors feature a wireless design, built-in cloud connectivity, and at least 3 years battery, so you’re ready for the worst the winter throws your way.
Onboard + Observe
When first signing in to your Wx Horizon account after install, you will quickly be onboarded to complete a brief onboarding. Once completed, your dashboard will begin to populate with observations and integrated forecast data from each of your Cast locations. Now you’re are ready to start making data-driven decisions.
"We get almost 50 inches of snow plus thawing every winter, and that creates hazardous driving conditions. Vaisala's insight and onboard tools let us target treatments faster and meet our levels of service."
