Road Weather Information
The NRA has a network of 54 weather monitoring stations and road sensors located on National Roads. These stations are part of an Ice Detection and Prediction System for the prediction and detection of ice formation on national roads during the winter months. Linked directly by modem, the meteorological information from the weather stations and road sensors is relayed to Met Eireann. The data is then used to give forecasts on ice locations on the network. The forecasts are automatically relayed to the relevant local authority and provide a valuable management tool to aid authorities with their road salting and snow ploughing programmes.
The web-pages below provide the actual readings from the road sensors as opposed to the forecasts. The information provided includes Road Surface Temperature, Air Temperature, Wind Speed, Wind Direction and the Road State i.e. whether there is ice, frost, snow, wet or whether the road has been treated.
The web-pages update automatically at 10 minutes past the hour to display the most recent readings from the road sensors usually taken on the hour.
