Not a lot of coverage of Maria on U.S. news channels.
I think the reason isn't (or isn't only) "it's not hitting the U.S. so who cares?" It's that there's not much actual information to convey. Current status of the storm, where it's headed, where the range of the uncertainty is, what kind of damage it could maybe cause (with plenty of hedging due to the forecast track uncertainties).
When it's headed for the U.S. they can fill hour after hour with boilerplate preparation warnings, footage of gas lines and sold-out stores, live video ("well, it was live the first of the 97 times we showed it") of rain falling into a puddle and a sidewalk cafe umbrella being knocked over by the mild winds a safe distance away from the storm, and so forth. Experts can come on and have interviews like:
"Jake, I was just on the phone with a local resident who says he's going to ride out the storm doing a handstand on the top of a billboard with cats glued to his torso. Is that a good plan, in your opinion?"
"No it's not, Marcia, and here's why..."
But when their vans and reporters aren't there, the people affected aren't tuned in to their network to hear their warnings, and footage of the actual damage won't be available for days, they're pretty much reduced to a three minute segment once per hourly cycle.
They have to figure out how to get politicians to come on and argue about where the storm should have gone instead and whose fault it is that it didn't.
