Even days after 4/27 damage reports and injuries/fatalities were subject to a LOT of rumors. I'm sure you remember. There was quite a bit said about the Tuscaloosa/Pleasant Grove tornado that didn't end up being true, and it was really insane that people made up those rumors to begin with because the damage was so horrific on its own. Power was still out, lots of cell towers were down. It took 5 or 6 days for us to get power back, and cell service was bad for a few months because a tower got cut in half in Tuscaloosa Co (I live right on the Jeffco/Tuscaloosa line)
I bet you remember some of the Tuscaloosa rumors quite well.
In a way, these things are similar to mass shootings. Early reports frequently include miscommunications, mischaracterizations, exaggerations, rumor, etc. Some of it is unintentional and in other cases people enjoy spreading shock rumors. Obviously, I know that's clearly not the case with your report as I saw the same one tweeted by Spann and I know you aren't that type of person.
As you said, tomorrow will bring a lot of clarity. Especially with aerial views, but we all know back in 2011 social media was in its infancy compared to today. I expect a lot of pictures will filter out as cell towers unclog, people get out to undamaged areas, etc. In fact, a lot of times the number of pictures coming out and how quickly can be an extremely rough gauge for how bad the infrastructure damage is if it's a populated area. May not be the case here because of spring break.
