Weather Warning Woes

Aside from the obvious typo in the title of this photo, this is pretty much the case this week. All sorts of weather people saying all sorts of weather things.  Here's where I have a problem.  One, I'm not such a fan of rain, wind and hurricane like conditions.  Call me crazy, but the possibility of a power outage for more than a few seconds, freaks me the heck out. Two, and most importantly, I have a trip planned to Texas next week and so help me god, if this darn storm messes up my flight, the weather gods are going to owe me some tacos!

What I don't understand about the storm is this.  I know science is slightly unpredictable, but isn't everyone who's everyone in the weather field, looking at the same darn swirling, raining, blowing storm?  How do so many people pick so many outcomes?  I've never really gotten that.  One hacker can break into a single specific computer across the world but a giant storm system stumps hundreds of weather people...WTH?!
