Why does the alert crawler appear only some of the time when there are National Weather Service alerts?


Depending on the affiliate, the Desktop Satellite may process alerts from several NWS offices. These offices may cover counties that are outside of the affiliate's area of interest.

All the alerts are decoded and displayed in the NWS tab of the Weather Center window. If the alert contains any counties that are in the area of interest of the affiliate then an alert crawler will also be triggered.
