 Using the customized settings in the WarnGen GUI, WarnGen translates the information into a text product that is displayed in a text window on the Text Display. The auto-generated text contains the storm speed and direction, the counties and cities affected by the warning/advisory, the valid times of the product, the warning/advisory body text (including any optional bullets selected in the GUI), and additional code to help our partners to efficiently process and disseminate the warning/advisory. The locked parts of the text are highlighted in blue and most of your text should not need to be edited if you configured your WarnGen window correctly.
