Fingal County Council is using MapAlerter since 2013 to issue alerts for all parts of the county. By signing up, you can select a mapped location in the county to ensure you only receive alerts that are locally relevant. For example, if you live in Swords then you will only get road alerts for this part of Fingal and you will not get alerts for any faraway places.
You also have the choice to add a Home and Work location so you can get alerts for both places along with commute alerts for any road issues between both places. For example, if you live in Balbriggan and work in Rush then you will receive alerts for both of these places along with any road alerts issued along the connecting route (R127, Skerries, R128, etc.).
