Well, there are different ways that people define "newsworthiness," but since this storm is by measure (882 mb) the most powerful hurricane to form in the Atlantic basin since records have been kept, I would say that the hurricane is newsworthy.
In light of the fact that two other destructive hurricanes also developed overnight from tropical storms into Category 5 hurricanes, causing death and destruction, it is worth noting.
It is noteworthy that this is the twelfth Atlantic hurricane for the season, meaning that this season is tied with one other for the most hurricanes in one season.
Personally, I'd rather have the information available to me, and make my choices based on it, rather than be completely unaware of a potential natural disaster. Some people might choose to ignore the reports, chalking it up to fear-mongering, some people might go over the top and start building a bomb shelter. And some of us fall in between, somewhere. But at least, since the information is available, you have a choice to do something with it, or nothing at all. Without that information, you're pretty much defaulted to doing nothing since you have no idea that there's a problem (like the poor folks in Galveston and Key West prior to technology which forecasts hurricanes).
Just my 2c.
