Better safe than sorry I suppose, and most people are stupid, and won't listen unless it's right under their nose.
That is the main reason I storm chase. Research has shown that people are close to 80% more likely to take shelter if they have visual proof a tornado is happening. So that is why I try to get out there and get pictures/video to send in to the NWS and media outlets.
Also, I'm not sure if all of you know, but there are different levels of tornado warnings that are issued based on certain criteria. These are standard across all NWS offices so doesn't matter where you live. Here is the verbiage you look for:
Severe thunderstorm capable of producing a tornado. Lowest confidence warning. Simply means that strong low level rotation has been detected on radar. No confirmation a tornado exists either from a chaser or radar signature. One could still be on the ground but hasn't been seen or too far from a radar site for it to detect debris.
Severe thunderstorm producing a tornado. This level warning is usually issued when there has been no visual confirmation, but radar has detected a debris signature indicating a tornado is on the ground producing damage and lofting debris into the air high enough for the radar to see it.
Confirmed tornado. Can be used interchangeably with the previous warning level, but one that has been confirmed visually will get this level warning,
PDS (Particularly Dangerous Situation) or Tornado Emergency. Highest level warning. This is a tornado that is confirmed either by radar or visually and is affecting, or about to affect a populated area. If it is not affecting a population center it will never get this level warning. Doesn't matter how big or violent it is.
