The warning covers north-central Jefferson Parish and southwestern Orleans Parish, not every block in New Orleans or the whole of Jefferson Parish. It is one product, FFWLIX, with one clock. The live alert is a new Flash Flood Warning. A Flood Advisory from the same office was already in effect for a wider area that includes these parishes. This page is only the Flash Flood Warning.
