Improvements in technology for severe weather monitoring and public warning have steadily increased the average advance warning time for the onset of hazardous weather. Weather information is now available through a wide variety of sources.
Even so, recently in a local jurisdiction, after a tornado struck a local mall, residents that were interviewed by the media stated that they "had no idea," and were "caught unaware" though advisories had been broadcast throughout the day and a tornado watch had been in effect for hours before.
