We provide a (U.S.) national map with all of the current severe weather zones (see link below). This map is updated in real time - as soon as Weather Underground receives updates from National Weather Service (NWS), this map and local radar overlays are updated.
Severe weather zones can be displayed as a layer on top of the local radar display. Look for a light blue bar containing links near the top of the local radar display.
- If the severe weather overlay is hidden, a link named "Show Severe" will appear -- click "Show Severe" to show the zone layer
- If the severe weather overlay is visible, a link named "No Severe" will appear -- click "No Severe" to hide the zone layer
