    1) I didn't think about that, good point. When I talk about how people receive warnings, I meant how they get the warning that prompted them to go into the shelter in the first place. I'll have to think about that in the future, though.

    2) When a tornado warning is issued and there is no tornado as a result, that is considered a false alarm. I asked one of my meteorology professors what he thought I should ask, and he suggested the false alarm/without warning questions. There's a known percentage of tornado warnings that are false alarms, and there's a known percentage of tornadoes that form without any sort of warning from the NWS. I designed that question on a scale from 1 to 10 to see if people get close to that percent (for instance...1 would be 10%, 9 would be 90%).

    3) Yes, sometimes tornadoes can occur without warning or detection. Low-topped convection occurs sometimes where the whole thunderstorm happens below the radar's beam, and goes undetected. This happened in Charlotte a few weeks ago...there was an EF-2 tornado on the east side of Charlotte NC that went undetected because the radar beam is 7,000 feet above the city, and the tornado's rotation occurred below 7,000 feet. Sometimes in situations such as squall lines or tropical systems making landfall, the tornado can happen so fast that it actually happens in between radar sweeps, so the radar never would have detected it anyway. It's improved drastically over the last few decades, but there's always room for improvement.
