This application lists out Flash Flood, Marine, Severe Thunderstorm, and Tornado Warnings issued by the National Weather Service for a given year. The listing includes metadata tags included in the initial warning or followup statements. IMPORTANT: Not all offices include these tags in their warnings! For convience, this application lists out warnings back to 2002 eventhough these tags did not start until recent years. You should be able to copy/paste these tables into Microsoft Excel prior to making the table sortable!
