This weekend I tweeted my concern about the potential impacts of Hurricane Florence later this week. Some guy chastised me for fear-mongering. I dismissed that as just typical Twitter posturing. I have spent my entire career as a meteorologist, at NASA and now as a University of Georgia professor, trying to combat weather hype and "social media-rology." If I say that I am worried about a storm with that level of aggressiveness, it looks to be a serious situation. I just told my family to alert people they know about Florence. Here are three reasons why I am so concerned.
