Wx Horizon continuously monitors all incoming data, notifying you instantly via SMS, email, or voice mail when conditions become hazardous anywhere on your network.
"Alabama gets a surprising amount of very diverse weather conditions, and some of it is impossible to predict. Wx Horizon pulls all the data we need from the TempCast and GroundCast sensors to give us the ground truth plus really accurate near-term forecasting in one place. We can be a lot more efficient and accurate in maintaining the road network, and it’s cost-effective which is important."
